10-19-06 - Version 3.1.14

    - Fixed BUG#20479 - Updatable result set throws ClassCastException
	  when there is row data and moveToInsertRow() is called.
	  
	- Fixed BUG#20485 - Updatable result set that contains
	  a BIT column fails when server-side prepared statements are used.
	  
	- Fixed BUG#16987 - Memory leak with profileSQL=true.
	
	- Fixed BUG#19726 - Connection fails to localhost when using 
	  timeout and IPv6 is configured.
	  
	- Fixed BUG#16791 - NullPointerException in MysqlDataSourceFactory
	  due to Reference containing RefAddrs with null content.
	  
	- Fixed BUG#20306 - ResultSet.getShort() for UNSIGNED TINYINT
	  returns incorrect values when using server-side prepared statements.
	  
	- Fixed BUG#20687 - Can't pool server-side prepared statements, exception
	  raised when re-using them.
	  
	- Fixed BUG#21062 - ResultSet.getSomeInteger() doesn't work for BIT(>1).
	
	- Fixed BUG#18880 - ResultSet.getFloatFromString() can't retrieve
	  values near Float.MIN/MAX_VALUE.
	  
	- Fixed BUG#20888 - escape of quotes in client-side prepared 
	  statements parsing not respected. Patch covers more than bug report, 
	  including NO_BACKSLASH_ESCAPES being set, and stacked quote characters
	  forms of escaping (i.e. '' or "").
	  
	- Fixed BUG#19993 - ReplicationDriver does not always round-robin load
	  balance depending on URL used for slaves list.
	
	- Fixed calling toString() on ResultSetMetaData for driver-generated
	  (i.e. from DatabaseMetaData method calls, or from getGeneratedKeys())
	  result sets would raise a NullPointerException.
	  
	- Fixed Bug#21207 - Driver throws NPE when tracing prepared statements that
	  have been closed (in asSQL()).
	  
	- Removed logger autodectection altogether, must now specify logger 
	  explitly if you want to use a logger other than one that logs
	  to STDERR.
	  
	- Fixed BUG#22290 - Driver issues truncation on write exception when
	  it shouldn't (due to sending big decimal incorrectly to server with
	  server-side prepared statement).
	  
	- Driver now sends numeric 1 or 0 for client-prepared statement
	  setBoolean() calls instead of '1' or '0'.
	  
	- Fixed bug where driver would not advance to next host if 
	  roundRobinLoadBalance=true and the last host in the list is down.

	- Fixed BUG#18258 - DatabaseMetaData.getTables(), columns() with bad
	  catalog parameter threw exception rather than return empty result
	  set (as required by spec).
	
	- Check and store value for continueBatchOnError property in constructor
      of Statements, rather than when executing batches, so that Connections
      closed out from underneath statements don't cause NullPointerExceptions
      when it's required to check this property.
      
    - Fixed bug when calling stored functions, where parameters weren't 
      numbered correctly (first parameter is now the return value, subsequent
      parameters if specified start at index "2").
      
	- Fixed BUG#21814 - time values outside valid range silently wrap.
	
05-26-06 - Version 3.1.13

    - Fixed BUG#15464 - INOUT parameter does not store IN value.
    
    - Fixed BUG#14609 - Exception thrown for new decimal type when 
      using updatable result sets.
      
    - Fixed BUG#15544, no "dos" character set in MySQL > 4.1.0
    
    - Fixed BUG#15383 - PreparedStatement.setObject() serializes 
      BigInteger as object, rather than sending as numeric value 
      (and is thus not complementary to .getObject() on an UNSIGNED 
      LONG type).
      
    - Fixed BUG#11874 - ResultSet.getShort() for UNSIGNED TINYINT
      returned wrong values. 
      
    - Fixed BUG#15676 - lib-nodist directory missing from  
      package breaks out-of-box build
      
    - Fixed BUG#15854 - DBMD.getColumns() returns wrong type for BIT.
    
    - Fixed BUG#14938 - Unable to initialize character set mapping tables. 
      Removed reliance on .properties files to hold this information, as it
      turns out to be too problematic to code around class loader hierarchies
      that change depending on how an application is deployed. Moved information
      back into the CharsetMapping class.
      
    - Fixed BUG#16841 - updatable result set doesn't return AUTO_INCREMENT 
      values for insertRow() when multiple column primary keys are used. (the
      driver was checking for the existence of single-column primary keys and
      an autoincrement value > 0 instead of a straightforward isAutoIncrement() 
      check).
      
    - Fixed BUG#17099 - Statement.getGeneratedKeys() throws NullPointerException 
      when no query has been processed.
      
    - Fixed BUG#13469 - Driver tries to call methods that don't exist on older and
      newer versions of Log4j. The fix is not trying to auto-detect presense of log4j, 
      too many different incompatible versions out there in the wild to do this reliably.
      
      If you relied on autodetection before, you will need to add 
      "logger=com.mysql.jdbc.log.Log4JLogger" to your JDBC URL to enable Log4J usage,
      or alternatively use the new "CommonsLogger" class to take care of this.
      
    - Added support for Apache Commons logging, use "com.mysql.jdbc.log.CommonsLogger"
      as the value for the "logger" configuration property.
      
    - LogFactory now prepends "com.mysql.jdbc.log" to log class name if it can't be
      found as-specified. This allows you to use "short names" for the built-in log
      factories, for example "logger=CommonsLogger" instead of 
      "logger=com.mysql.jdbc.log.CommonsLogger".
      
    - Fixed BUG#15570 - ReplicationConnection incorrectly copies state,
	  doesn't transfer connection context correctly when transitioning between 
	  the same read-only states.
	  
	- Fixed BUG#18041 - Server-side prepared statements don't cause 
	  truncation exceptions to be thrown when truncation happens.
	  
	- Added performance feature, re-writing of batched executes for
	  Statement.executeBatch() (for all DML statements) and 
	  PreparedStatement.executeBatch() (for INSERTs with VALUE clauses 
	  only). Enable by using "rewriteBatchedStatements=true" in your JDBC URL.
	  
	- Fixed BUG#17898 - registerOutParameter not working when some 
	  parameters pre-populated. Still waiting for feedback from JDBC experts
	  group to determine what correct parameter count from getMetaData() 
	  should be, however.
	  
	- Fixed BUG#17587 - clearParameters() on a closed prepared statement
	  causes NPE.
	  
	- Map "latin1" on MySQL server to CP1252 for MySQL > 4.1.0.
	
	- Added additional accessor and mutator methods on ConnectionProperties
	  so that DataSource users can use same naming as regular URL properties.
	  
	- Fixed BUG#18740 - Data truncation and getWarnings() only returns last 
	  warning in set.
	  
	- Improved performance of retrieving BigDecimal, Time, Timestamp and Date
	  values from server-side prepared statements by creating fewer short-lived
	  instances of Strings when the native type is not an exact match for
	  the requested type. Fixes BUG#18496 for BigDecimals.
	  
	- Fixed BUG#18554 - Aliased column names where length of name > 251 
	  are corrupted.
	  
	- Fixed BUG#17450 - ResultSet.wasNull() not always reset
	  correctly for booleans when done via conversion for server-side
	  prepared statements.
	  
	- Fixed BUG#16277 - Invalid classname returned for 
	  RSMD.getColumnClassName() for BIGINT type.
	
	- Fixed case where driver wasn't reading server status correctly when 
	  fetching server-side prepared statement rows, which in some cases 
	  could cause warning counts to be off, or multiple result sets to not 
	  be read off the wire.
	  
	- Driver now aware of fix for BIT type metadata that went into 
	  MySQL-5.0.21 for server not reporting length consistently (bug 
	  number 13601).
	  
	- Fixed BUG#19615, PreparedStatement.setObject(int, Object, int)
	  doesn't respect scale of BigDecimals.
	  
	- Fixed BUG#19282 - ResultSet.wasNull() returns incorrect value 
	  when extracting native string from server-side prepared statement 
	  generated result set.
	  
	- Fixed BUG#19568 - ResultSet.getSomeNumeric() didn't work for the
	  BIT type.
	  
	- Fixed BUG#19724 - Updatable result set fails when server is in ANSI
	  sql_mode.

11-30-05 - Version 3.1.12

    - Fixed client-side prepared statement bug with embedded ? inside
      quoted identifiers (it was recognized as a placeholder, when it
      was not).
      
    - Don't allow executeBatch() for CallableStatements with registered
      OUT/INOUT parameters (JDBC compliance).
      
    - Fall back to platform-encoding for URLDecoder.decode() when
      parsing driver URL properties if the platform doesn't have a 
      two-argument version of this method.
      
    - Fixed BUG#14562 - Java type conversion may be incorrect for 
      mediumint.
      
    - Added configuration property "useGmtMillisForDatetimes" which
      when set to true causes ResultSet.getDate(), .getTimestamp() to
      return correct millis-since GMT when .getTime() is called on 
      the return value (currently default is "false" for legacy
      behavior).

    - Fixed DatabaseMetaData.stores*Identifiers():
    
        * if lower_case_table_names=0 (on server):
        
            storesLowerCaseIdentifiers() returns false
            storesLowerCaseQuotedIdentifiers() returns false
            storesMixedCaseIdentifiers() returns true
            storesMixedCaseQuotedIdentifiers() returns true
            storesUpperCaseIdentifiers() returns false
            storesUpperCaseQuotedIdentifiers() returns true 
                
        * if lower_case_table_names=1 (on server):
        
            storesLowerCaseIdentifiers() returns true
            storesLowerCaseQuotedIdentifiers() returns true
            storesMixedCaseIdentifiers() returns false
            storesMixedCaseQuotedIdentifiers() returns false
            storesUpperCaseIdentifiers() returns false
            storesUpperCaseQuotedIdentifiers() returns true 
 
    - Fixed BUG#14815 - DatabaseMetaData.getColumns() doesn't
      return TABLE_NAME correctly.
      
    - Fixed BUG#14909 - escape processor replaces quote character 
      in quoted string with string delimiter.
      
    - Fixed BUG#12975 - OpenOffice expects 
      DBMD.supportsIntegrityEnhancementFacility() to return "true" 
      if foreign keys are supported by the datasource, even though 
      this method also covers support for check constraints,
	  which MySQL _doesn't_ have. Setting the configuration property
	  "overrideSupportsIntegrityEnhancementFacility" to "true" causes
	  the driver to return "true" for this method.
	  
	- Added "com.mysql.jdbc.testsuite.url.default" system property to
	  set default JDBC url for testsuite (to speed up bug resolution
	  when I'm working in Eclipse).
	  
	- Fixed BUG#14938 - Unable to initialize character set mapping 
	  tables (due to J2EE classloader differences).
	  
	- Fixed BUG#14972 - Deadlock while closing server-side prepared
	  statements from multiple threads sharing one connection.
	  
	- Fixed BUG#12230 -	logSlowQueries should give better info.
	
	- Fixed BUG#13775 - Extraneous sleep on autoReconnect.
	
	- Fixed BUG#15024 - Driver incorrectly closes streams passed as 
	  arguments to PreparedStatements. Reverts to legacy behavior by
	  setting the JDBC configuration property "autoClosePStmtStreams"
	  to "true" (also included in the 3-0-Compat configuration "bundle").
	  
	- Fixed BUG#13048 - maxQuerySizeToLog is not respected. Added logging of
	  bound values for execute() phase of server-side prepared statements
	  when profileSQL=true as well.
	  
	- Fixed BUG#15065 - Usage advisor complains about unreferenced 
	  columns, even though they've been referenced.
	  
	- Don't increase timeout for failover/reconnect (BUG#6577)
	
	- Process escape tokens in Connection.prepareStatement(...), fix
	  for BUG#15141. You can disable this behavior by setting 
	  the JDBC URL configuration property "processEscapeCodesForPrepStmts"
	  to "false".
	  
	- Fixed BUG#13255 - Reconnect during middle of executeBatch() 
	  should not occur if autoReconnect is enabled.
      
10-07-05 - Version 3.1.11

    - Fixed BUG#11629 - Spurious "!" on console when character
      encoding is "utf8".
      
    - Fixed statements generated for testcases missing ";" for
      "plain" statements.
      
    - Fixed BUG#11663 - Incorrect generation of testcase scripts 
      for server-side prepared statements.
      
    - Fixed regression caused by fix for BUG#11552 that caused driver
      to return incorrect values for unsigned integers when those 
      integers where within the range of the positive signed type.
    
    - Moved source code to svn repo.
    
    - Fixed BUG#11797 - Escape tokenizer doesn't respect stacked single quotes
	  for escapes.
	  
	- GEOMETRY type not recognized when using server-side prepared statements.
    
    - Fixed BUG#11879 -- ReplicationConnection won't switch to slave, throws 
      "Catalog can't be null" exception.
      
    - Fixed BUG#12218, properties shared between master and slave with 
      replication connection.
      
    - Fixed BUG#10630, Statement.getWarnings() fails with NPE if statement 
      has been closed.
      
    - Only get char[] from SQL in PreparedStatement.ParseInfo() when needed.
    
    - Fixed BUG#12104 - Geometry types not handled with server-side prepared 
      statements.
      
    - Fixed BUG#11614 - StringUtils.getBytes() doesn't work when using 
      multibyte character encodings and a length in  _characters_ is 
      specified.
      
    - Fixed BUG#11798 - Pstmt.setObject(...., Types.BOOLEAN) throws exception.
    
    - Fixed BUG#11976 - maxPerformance.properties mis-spells 
	  "elideSetAutoCommits".
	  
	- Fixed BUG#11575 -- DBMD.storesLower/Mixed/UpperIdentifiers()
	  reports incorrect values for servers deployed on Windows.
	  
	- Fixed BUG#11190 - ResultSet.moveToCurrentRow() fails to work when 
	  preceeded by a call to ResultSet.moveToInsertRow().
	  
	- Fixed BUG#11115, VARBINARY data corrupted when using server-side
	  prepared statements and .setBytes().
	
	- Fixed BUG#12229 - explainSlowQueries hangs with server-side
	  prepared statements.
	  
	- Fixed BUG#11498 - Escape processor didn't honor strings demarcated
	  with double quotes.
	  
	- Lifted restriction of changing streaming parameters with server-side
	  prepared statements. As long as _all_ streaming parameters were set
	  before execution, .clearParameters() does not have to be called. 
	  (due to limitation of client/server protocol, prepared statements
	   can not reset _individual_ stream data on the server side).
	   
	- Reworked Field class, *Buffer, and MysqlIO to be aware of field
	  lengths > Integer.MAX_VALUE.
	  
	- Updated DBMD.supportsCorrelatedQueries() to return true for versions > 
	  4.1, supportsGroupByUnrelated() to return true and 
	  getResultSetHoldability() to return HOLD_CURSORS_OVER_COMMIT.
	  
	- Fixed BUG#12541 - Handling of catalog argument in 
	  DatabaseMetaData.getIndexInfo(), which also means changes to the following
	  methods in DatabaseMetaData:
	  
	    - getBestRowIdentifier()
	    - getColumns()
	    - getCrossReference()
	    - getExportedKeys()
	    - getImportedKeys()
	    - getIndexInfo()
	    - getPrimaryKeys()
	    - getProcedures() (and thus indirectly getProcedureColumns())
	    - getTables()
	  
	  The "catalog" argument in all of these methods now behaves in the following
	  way:
	  
	    - Specifying NULL means that catalog will not be used to filter the
	      results (thus all databases will be searched), unless you've
	      set "nullCatalogMeansCurrent=true" in your JDBC URL properties.
	      
	    - Specifying "" means "current" catalog, even though this isn't quite
	      JDBC spec compliant, it's there for legacy users.
	      
	    - Specifying a catalog works as stated in the API docs.
	    
	- Made Connection.clientPrepare() available from "wrapped" connections
	  in the jdbc2.optional package (connections built by 
	  ConnectionPoolDataSource instances).
      
    - Added Connection.isMasterConnection() for clients to be able to determine
      if a multi-host master/slave connection is connected to the first host
      in the list.
      
    - Fixed BUG#12753 - Tokenizer for "=" in URL properties was causing
      sessionVariables=.... to be parameterized incorrectly.

    - Fixed BUG#11781, foreign key information that is quoted is 
      parsed incorrectly when DatabaseMetaData methods use that
      information.
      
    - The "sendBlobChunkSize" property is now clamped to "max_allowed_packet"
      with consideration of stream buffer size and packet headers to avoid
      PacketTooBigExceptions when "max_allowed_packet" is similar in size
      to the default "sendBlobChunkSize" which is 1M.
      
    - CallableStatement.clearParameters() now clears resources associated
      with INOUT/OUTPUT parameters as well as INPUT parameters.
      
    - Fixed BUG#12417 - Connection.prepareCall() is database name 
      case-sensitive (on Windows systems).
      
    - Fixed BUG#12752 - Cp1251 incorrectly mapped to win1251 for 
      servers newer than 4.0.x.
      
    - Fixed BUG#12970 - java.sql.Types.OTHER returned for 
	  BINARY and VARBINARY columns when using 
	  DatabaseMetaData.getColumns(). 
	  
	- ServerPreparedStatement.getBinding() now checks if the statement
	  is closed before attempting to reference the list of parameter
	  bindings, to avoid throwing a NullPointerException.
      
    - Fixed BUG#13277 - ResultSetMetaData from 
      Statement.getGeneratedKeys() caused NullPointerExceptions to be
      thrown whenever a method that required a connection reference
      was called.
      
    - Backport of Field class, ResultSetMetaData.getColumnClassName(),
      and ResultSet.getObject(int) changes from 5.0 branch to fix
      behavior surrounding VARCHAR BINARY/VARBINARY and related
      types.
      
    - Fixed NullPointerException when converting "catalog" parameter
      in many DatabaseMetaDataMethods to byte[]s (for the result set)
      when the parameter is null. ("null" isn't technically allowed
      by the JDBC specification, but we've historically allowed it).
      
    - Backport of VAR[BINARY|CHAR] [BINARY] types detection from 
      5.0 branch.
    
    - Read response in MysqlIO.sendFileToServer(), even if the 
      local file can't be opened, otherwise next query issued
      will fail, because it's reading the response to the empty
      LOAD DATA INFILE packet sent to the server.
      
    - Workaround for BUG#13374 - ResultSet.getStatement() 
	  on closed result set returns NULL (as per JDBC 4.0 spec,
	  but not backwards-compatible). Set the connection property
	  "retainStatementAfterResultSetClose" to "true" to be able
	  to retrieve a ResultSet's statement after the ResultSet has
	  been closed via .getStatement() (the default is "false", to
	  be JDBC-compliant and to reduce the chance that code using
	  JDBC leaks Statement instances).
      
    - Fixed BUG#13453 - URL configuration parameters don't allow
      '&' or '=' in their values. The JDBC driver now parses 
      configuration parameters as if they are encoded using the 
      application/x-www-form-urlencoded format as specified
      by java.net.URLDecoder - 
      http://java.sun.com/j2se/1.5.0/docs/api/java/net/URLDecoder.html
      
      If the '%' character is present in a configuration property,
      it must now be represented as %25, which is the encoded form
      of '%' when using application/x-www-form-urlencoded encoding.
      
    - The configuration property "sessionVariables" now allows you to
      specify variables that start with the "@" sign.
      
    - Fixed BUG#13043 - when 'gatherPerfMetrics' is enabled for 
      servers older than 4.1.0, a NullPointerException is thrown from 
      the constructor of ResultSet if the query doesn't use any tables.
      
06-23-05 - Version 3.1.10-stable

	- Fixed connecting without a database specified raised an exception
	  in MysqlIO.changeDatabaseTo().
	  
	- Initial implemention of ParameterMetadata for 
	  PreparedStatement.getParameterMetadata(). Only works fully
	  for CallableStatements, as current server-side prepared statements
	  return every parameter as a VARCHAR type.
	  
	- Fixed BUG#11552 - Server-side prepared statements return incorrect
	  values for unsigned TINYINT, SMALLINT, INT and Long.
	  
	- Fixed BUG#11540 - Incorrect year conversion in setDate(..) for 
	  system that use B.E. year in default locale.
	  
06-22-05 - Version 3.1.9-stable
	
	- Overhaul of character set configuration, everything now
	  lives in a properties file.
	  
	- Driver now correctly uses CP932 if available on the server
	  for Windows-31J, CP932 and MS932 java encoding names, 
	  otherwise it resorts to SJIS, which is only a close 
	  approximation. Currently only MySQL-5.0.3 and newer (and
	  MySQL-4.1.12 or .13, depending on when the character set
	  gets backported) can reliably support any variant of CP932.
	  
	- Fixed BUG#9064 - com.mysql.jdbc.PreparedStatement.ParseInfo 
	  does unnecessary call to toCharArray().
	  
	- Fixed Bug#10144 - Memory leak in ServerPreparedStatement if 
	  serverPrepare() fails.
	  
	- Actually write manifest file to correct place so it ends up
	  in the binary jar file.
	  
	- Added "createDatabaseIfNotExist" property (default is "false"),
	  which will cause the driver to ask the server to create the 
	  database specified in the URL if it doesn't exist. You must have
	  the appropriate privileges for database creation for this to
	  work.
	  
	- Fixed BUG#10156 - Unsigned SMALLINT treated as signed for ResultSet.getInt(),
	  fixed all cases for UNSIGNED integer values and server-side prepared statements,
	  as well as ResultSet.getObject() for UNSIGNED TINYINT.
	  
	- Fixed BUG#10155, double quotes not recognized when parsing 
	  client-side prepared statements.
	  
	- Made enableStreamingResults() visible on 
	  com.mysql.jdbc.jdbc2.optional.StatementWrapper.
	  
	- Made ServerPreparedStatement.asSql() work correctly so auto-explain
	  functionality would work with server-side prepared statements.
	  
	- Made JDBC2-compliant wrappers public in order to allow access to
	  vendor extensions.
	  
	- Cleaned up logging of profiler events, moved code to dump a profiler
	  event as a string to com.mysql.jdbc.log.LogUtils so that third
	  parties can use it.
	  
	- DatabaseMetaData.supportsMultipleOpenResults() now returns true. The
	  driver has supported this for some time, DBMD just missed that fact.
	  
	- Fixed BUG#10310 - Driver doesn't support {?=CALL(...)} for calling
	  stored functions. This involved adding support for function retrieval
	  to DatabaseMetaData.getProcedures() and getProcedureColumns() as well.
	  
	- Fixed BUG#10485, SQLException thrown when retrieving YEAR(2) 
	  with ResultSet.getString(). The driver will now always treat YEAR types
	  as java.sql.Dates and return the correct values for getString(). 
	  Alternatively, the "yearIsDateType" connection property can be set to
	  "false" and the values will be treated as SHORTs.
	  
	- The datatype returned for TINYINT(1) columns when "tinyInt1isBit=true" 
	  (the default) can be switched between Types.BOOLEAN and Types.BIT
	  using the new configuration property "transformedBitIsBoolean", which
	  defaults to "false". If set to "false" (the default), 
	  DatabaseMetaData.getColumns() and ResultSetMetaData.getColumnType() 
	  will return Types.BOOLEAN for TINYINT(1) columns. If "true", 
	  Types.BOOLEAN will be returned instead. Irregardless of this configuration
	  property, if "tinyInt1isBit" is enabled, columns with the type TINYINT(1)
	  will be returned as java.lang.Boolean instances from 
	  ResultSet.getObject(..), and ResultSetMetaData.getColumnClassName()
	  will return "java.lang.Boolean".
	 
	- Fixed BUG#10496 - SQLException is thrown when using property 
	  "characterSetResults" with cp932 or eucjpms.
	  
	- Reorganized directory layout, sources now in "src" folder,
	  don't pollute parent directory when building, now output goes
	  to "./build", distribution goes to "./dist".
	  
	- Added support/bug hunting feature that generates .sql test
	  scripts to STDERR when "autoGenerateTestcaseScript" is set
	  to "true".
	  
	- Fixed BUG#10850 - 0-length streams not sent to server when
	  using server-side prepared statements.
	
	- Setting "cachePrepStmts=true" now causes the Connection to also 
	  cache the check the driver performs to determine if a prepared 
	  statement can be server-side or not, as well as caches server-side
	  prepared statements for the lifetime of a connection. As before,
	  the "prepStmtCacheSize" parameter controls the size of these
	  caches.
	  
	- Try to handle OutOfMemoryErrors more gracefully. Although not
	  much can be done, they will in most cases close the connection
	  they happened on so that further operations don't run into 
	  a connection in some unknown state. When an OOM has happened, 
	  any further operations on the connection will fail with a 
	  "Connection closed" exception that will also list the OOM exception
	  as the reason for the implicit connection close event.
	  
	- Don't send COM_RESET_STMT for each execution of a server-side
	  prepared statement if it isn't required.
	  
	- Driver detects if you're running MySQL-5.0.7 or later, and does
	  not scan for "LIMIT ?[,?]" in statements being prepared, as the
	  server supports those types of queries now.
	  
	- Fixed BUG#11115, Varbinary data corrupted when using server-side
	  prepared statements and ResultSet.getBytes().
	  
	- Connection.setCatalog() is now aware of the "useLocalSessionState"
	  configuration property, which when set to true will prevent
	  the driver from sending "USE ..." to the server if the requested
	  catalog is the same as the current catalog.
	  
	- Added the following configuration bundles, use one or many via
	  the "useConfigs" configuration property:
	
	    * maxPerformance -- maximum performance without being reckless
	    * solarisMaxPerformance -- maximum performance for Solaris,
	                               avoids syscalls where it can
	    * 3-0-Compat -- Compatibility with Connector/J 3.0.x functionality
	    
	- Added "maintainTimeStats" configuration property (defaults to "true"),
	  which tells the driver whether or not to keep track of the last query time
	  and the last successful packet sent to the server's time. If set to
	  false, removes two syscalls per query.
	
	- Fixed BUG#11259, autoReconnect ping causes exception on connection 
	  startup.
	  
	- Fixed BUG#11360 Connector/J dumping query into SQLException twice
	
	- Fixed PreparedStatement.setClob() not accepting null as a parameter.
	
	- Fixed BUG#11411 - Production package doesn't include JBoss integration 
	  classes.
	  
	- Removed nonsensical "costly type conversion" warnings when using 
	  usage advisor.

04-14-05 - Version 3.1.8-stable

	- Fixed DatabaseMetaData.getTables() returning views when they were 
	  not asked for as one of the requested table types.
	  
	- Added support for new precision-math DECIMAL type in MySQL >= 5.0.3.
	
	- Fixed ResultSet.getTime() on a NULL value for server-side prepared
	  statements throws NPE.
	  
	- Made Connection.ping() a public method.
	
	- Fixed Bug#8868, DATE_FORMAT() queries returned as BLOBs from getObject().
	
	- ServerPreparedStatements now correctly 'stream' BLOB/CLOB data to the
	  server. You can configure the threshold chunk size using the
	  JDBC URL property 'blobSendChunkSize' (the default is one megabyte).
	  
    - BlobFromLocator now uses correct identifier quoting when generating
      prepared statements.
      
    - Server-side session variables can be preset at connection time by
      passing them as a comma-delimited list for the connection property 
      'sessionVariables'.

	- Fixed regression in ping() for users using autoReconnect=true.
	
	- Fixed BUG#9040 - PreparedStatement.addBatch() doesn't work with server-side 
	  prepared statements and streaming BINARY data.
	  
	- Fixed BUG#8800 - DBMD.supportsMixedCase*Identifiers() returns wrong
	  value on servers running on case-sensitive filesystems.
	
	- Fixed BUG#9206, can not use 'UTF-8' for characterSetResults
      configuration property.
      
    - Fixed BUG#9236, a continuation of BUG#8868, where functions used in queries 
      that should return non-string types when resolved by temporary tables suddenly 
      become opaque binary strings (work-around for server limitation). Also fixed
      fields with type of CHAR(n) CHARACTER SET BINARY to return correct/matching
      classes for RSMD.getColumnClassName() and ResultSet.getObject().
    
    - Fixed BUG#8792 - DBMD.supportsResultSetConcurrency() not returning
	  true for forward-only/read-only result sets (we obviously support this).
	  
	- Fixed BUG#8803, 'DATA_TYPE' column from DBMD.getBestRowIdentifier()
	  causes ArrayIndexOutOfBoundsException when accessed (and in fact, didn't
	  return any value).
	  
	- Check for empty strings ('') when converting char/varchar column data to numbers,
	  throw exception if 'emptyStringsConvertToZero' configuration property is set
	  to 'false' (for backwards-compatibility with 3.0, it is now set to 'true' 
	  by default, but will most likely default to 'false' in 3.2).
	  
	- Fixed BUG#9320 - PreparedStatement.getMetaData() inserts blank row in database 
	  under certain conditions when not using server-side prepared statements.
	  
	- Connection.canHandleAsPreparedStatement() now makes 'best effort' to distinguish
	  LIMIT clauses with placeholders in them from ones without in order to have fewer
	  false positives when generating work-arounds for statements the server cannot 
	  currently handle as server-side prepared statements.
	  
	- Fixed build.xml to not compile log4j logging if log4j not available.
	
	- Added support for the c3p0 connection pool's (http://c3p0.sf.net/) 
	  validation/connection checker interface which uses the lightweight 
	  'COM_PING' call to the server if available. To use it, configure your
	  c3p0 connection pool's 'connectionTesterClassName' property to use
	  'com.mysql.jdbc.integration.c3p0.MysqlConnectionTester'.
	  
	- Better detection of LIMIT inside/outside of quoted strings so that
	  the driver can more correctly determine whether a prepared statement
	  can be prepared on the server or not.
	
	- Fixed BUG#9319 - Stored procedures with same name in 
	  different databases confuse the driver when it tries to determine
	  parameter counts/types.
  
    - Added finalizers to ResultSet and Statement implementations to be JDBC
      spec-compliant, which requires that if not explicitly closed, these 
      resources should be closed upon garbage collection.
      
    - Fixed BUG#9682 - Stored procedures with DECIMAL parameters with
	  storage specifications that contained "," in them would fail.
	  
	- PreparedStatement.setObject(int, Object, int type, int scale) now 
	  uses scale value for BigDecimal instances.
	  
	- Fixed BUG#9704 - Statement.getMoreResults() could throw NPE when
	  existing result set was .close()d.
	  
	- The performance metrics feature now gathers information about
	  number of tables referenced in a SELECT.
	
	- The logging system is now automatically configured. If the value has 
	  been set by the user, via the URL property "logger" or the system 
	  property "com.mysql.jdbc.logger", then use that, otherwise, autodetect 
	  it using the following steps:
	  
    	 Log4j, if it's available,
    	 Then JDK1.4 logging,
    	 Then fallback to our STDERR logging.
    	 
   	- Fixed BUG#9778, DBMD.getTables() shouldn't return tables if views
	  are asked for, even if the database version doesn't support views.
	  
	- Fixed driver not returning 'true' for '-1' when ResultSet.getBoolean()
	  was called on result sets returned from server-side prepared statements.
	  
	- Added a Manifest.MF file with implementation information to the .jar
	  file.
	  
	- More tests in Field.isOpaqueBinary() to distinguish opaque binary (i.e. 
	  fields with type CHAR(n) and CHARACTER SET BINARY) from output of 
	  various scalar and aggregate functions that return strings.
	  
	- Fixed BUG#9917 - Should accept null for catalog (meaning use current) 
	  in DBMD methods, even though it's not JDBC-compliant for legacy's sake.
	  Disable by setting connection property "nullCatalogMeansCurrent" to "false"
	  (which will be the default value in C/J 3.2.x).
	  
	- Fixed BUG#9769 - Should accept null for name patterns in DBMD (meaning "%"), 
	  even though it isn't JDBC compliant, for legacy's sake. Disable by setting
	  connection property "nullNamePatternMatchesAll" to "false" (which will be 
	  the default value in C/J 3.2.x).
	  	 
02-18-05 - Version 3.1.7-stable


    - Fixed BUG#7686, Timestamp key column data needed "_binary'"
      stripped for UpdatableResultSet.refreshRow().

    - Fixed BUG#7715 - Timestamps converted incorrectly to strings
      with Server-side prepared statements and updatable result sets.

    - Detect new sql_mode variable in string form (it used to be 
      integer) and adjust quoting method for strings appropriately.

    - Added 'holdResultsOpenOverStatementClose' property (default is
      false), that keeps result sets open over statement.close() or new
      execution on same statement (suggested by Kevin Burton).

    - Fixed BUG#7952 -- Infinite recursion when 'falling back' to master
      in failover configuration.

    - Disable multi-statements (if enabled) for MySQL-4.1 versions prior
      to version 4.1.10 if the query cache is enabled, as the server
      returns wrong results in this configuration.

    - Fixed duplicated code in configureClientCharset() that prevented
      useOldUTF8Behavior=true from working properly.

    - Removed 'dontUnpackBinaryResults' functionality, the driver now
      always stores results from server-side prepared statements as-is
      from the server and unpacks them on demand.

    - Fixed BUG#8096 where emulated locators corrupt binary data
      when using server-side prepared statements.

    - Fixed synchronization issue with
      ServerPreparedStatement.serverPrepare() that could cause
      deadlocks/crashes if connection was shared between threads.

    - By default, the driver now scans SQL you are preparing via all
      variants of Connection.prepareStatement() to determine if it is a
      supported type of statement to prepare on the server side, and if
      it is not supported by the server, it instead prepares it as a
      client-side emulated prepared statement (BUG#4718). You can
      disable this by passing 'emulateUnsupportedPstmts=false' in your
      JDBC URL.

    - Remove _binary introducer from parameters used as in/out
      parameters in CallableStatement.

    - Always return byte[]s for output parameters registered as *BINARY.

    - Send correct value for 'boolean' "true" to server for
      PreparedStatement.setObject(n, "true", Types.BIT).

    - Fixed bug with Connection not caching statements from
      prepareStatement() when the statement wasn't a server-side
      prepared statement.

    - Choose correct 'direction' to apply time adjustments when both
      client and server are in GMT timezone when using
      ResultSet.get(..., cal) and PreparedStatement.set(...., cal).

    - Added 'dontTrackOpenResources' option (default is false, to be
      JDBC compliant), which helps with memory use for non-well-behaved
      apps (i.e applications which don't close Statements when they
      should).

    - Fixed BUG#8428 - ResultSet.getString() doesn't maintain format
      stored on server, bug fix only enabled when 'noDatetimeStringSync'
      property is set to 'true' (the default is 'false').

    - Fixed NPE in ResultSet.realClose() when using usage advisor and
      result set was already closed.

    - Fixed BUG#8487 - PreparedStatements not creating streaming result
      sets.

    - Don't pass NULL to String.valueOf() in
      ResultSet.getNativeConvertToString(), as it stringifies it (i.e.
      returns "null"), which is not correct for the method in question.

    - Fixed BUG#8484 - ResultSet.getBigDecimal() throws exception
      when rounding would need to occur to set scale. The driver now
      chooses a rounding mode of 'half up' if non-rounding
      BigDecimal.setScale() fails.

    - Added 'useLocalSessionState' configuration property, when set to
      'true' the JDBC driver trusts that the application is well-behaved
      and only sets autocommit and transaction isolation levels using
      the methods provided on java.sql.Connection, and therefore can
      manipulate these values in many cases without incurring
      round-trips to the database server.

    - Added enableStreamingResults() to Statement for connection pool
      implementations that check Statement.setFetchSize() for 
      specification-compliant values. Call Statement.setFetchSize(>=0) 
      to disable the streaming results for that statement.

    - Added support for BIT type in MySQL-5.0.3. The driver will treat
      BIT(1-8) as the JDBC standard BIT type (which maps to
      java.lang.Boolean), as the server does not currently send enough
      information to determine the size of a bitfield when < 9 bits are
      declared. BIT(>9) will be treated as VARBINARY, and will return
      byte[] when getObject() is called.
      
12-23-04 - Version 3.1.6-stable

    - Fixed hang on SocketInputStream.read() with Statement.setMaxRows() and 
      multiple result sets when driver has to truncate result set directly, 
      rather than tacking a 'LIMIT n' on the end of it.
      
    - Fixed BUG#7026 - DBMD.getProcedures() doesn't respect catalog parameter.
    
    - Respect bytes-per-character for RSMD.getPrecision().
      
12-02-04 - Version 3.1.5-gamma

	- Fix comparisons made between string constants and dynamic strings that
	  are either toUpperCase()d or toLowerCase()d to use Locale.ENGLISH, as 
	  some locales 'override' case rules for English. Also use 
	  StringUtils.indexOfIgnoreCase() instead of .toUpperCase().indexOf(), 
	  avoids creating a very short-lived transient String instance.
	
	- Fixed BUG#5235 - Server-side prepared statements did not honor
      'zeroDateTimeBehavior' property, and would cause class-cast
      exceptions when using ResultSet.getObject(), as the all-zero string
      was always returned.
      
    - Fixed batched updates with server prepared statements weren't looking if
      the types had changed for a given batched set of parameters compared
      to the previous set, causing the server to return the error 
      'Wrong arguments to mysql_stmt_execute()'.
      
    - Handle case when string representation of timestamp contains trailing '.'
      with no numbers following it.
      
    - Fixed BUG#5706 - Inefficient detection of pre-existing string instances
      in ResultSet.getNativeString().
      
    - Don't throw exceptions for Connection.releaseSavepoint().
    
    - Use a per-session Calendar instance by default when decoding dates
      from ServerPreparedStatements (set to old, less performant behavior by 
      setting property 'dynamicCalendars=true').
      
    - Added experimental configuration property 'dontUnpackBinaryResults', 
      which delays unpacking binary result set values until they're asked for, 
      and only creates object instances for non-numerical values (it is set 
      to 'false' by default). For some usecase/jvm combinations, this is 
      friendlier on the garbage collector.
      
    - Fixed BUG#5729 - UNSIGNED BIGINT unpacked incorrectly from
      server-side prepared statement result sets.
      
    - Fixed BUG#6225 - ServerSidePreparedStatement allocating short-lived
      objects un-necessarily.
      
    - Removed un-wanted new Throwable() in ResultSet constructor due to bad
      merge (caused a new object instance that was never used for every result
      set created) - Found while profiling for BUG#6359.
      
    - Fixed too-early creation of StringBuffer in EscapeProcessor.escapeSQL(),
      also return String when escaping not needed (to avoid unnecssary object
      allocations). Found while profiling for BUG#6359.
      
    - Use null-safe-equals for key comparisons in updatable result sets.
    
    - Fixed BUG#6537, SUM() on Decimal with server-side prepared statement ignores
      scale if zero-padding is needed (this ends up being due to conversion to DOUBLE
      by server, which when converted to a string to parse into BigDecimal, loses all
      'padding' zeros).

    - Use DatabaseMetaData.getIdentifierQuoteString() when building DBMD
      queries.
      
    - Use 1MB packet for sending file for LOAD DATA LOCAL INFILE if that
      is < 'max_allowed_packet' on server.
      
    - Fixed BUG#6399, ResultSetMetaData.getColumnDisplaySize() returns incorrect
      values for multibyte charsets.
      
    - Make auto-deserialization of java.lang.Objects stored in BLOBs 
      configurable via 'autoDeserialize' property (defaults to 'false').
      
    - Re-work Field.isOpaqueBinary() to detect 'CHAR(n) CHARACTER SET BINARY'
      to support fixed-length binary fields for ResultSet.getObject().
      
    - Use our own implementation of buffered input streams to get around 
      blocking behavior of java.io.BufferedInputStream. Disable this with
      'useReadAheadInput=false'.
    
    - Fixed BUG#6348, failing to connect to the server when one of the
      addresses for the given host name is IPV6 (which the server does
      not yet bind on). The driver now loops through _all_ IP addresses
      for a given host, and stops on the first one that accepts() a 
      socket.connect().
      
09-04-04 - Version 3.1.4-beta

    - Fixed BUG#4510 - connector/j 3.1.3 beta does not handle integers 
      correctly (caused by changes to support unsigned reads in
      Buffer.readInt() -> Buffer.readShort()).
    
    - Added support in DatabaseMetaData.getTables() and getTableTypes() 
      for VIEWs which are now available in MySQL server version 5.0.x.
    
    - Fixed BUG#4642 -- ServerPreparedStatement.execute*() sometimes
      threw ArrayIndexOutOfBoundsException when unpacking field metadata.
    
    - Optimized integer number parsing, enable 'old' slower integer parsing 
      using JDK classes via 'useFastIntParsing=false' property.
    
    - Added 'useOnlyServerErrorMessages' property, which causes message text
      in exceptions generated by the server to only contain the text sent by
      the server (as opposed to the SQLState's 'standard' description, followed
      by the server's error message). This property is set to 'true' by default.
    
    - Fixed BUG#4689 - ResultSet.wasNull() does not work for primatives if a 
      previous null was returned.
    
    - Track packet sequence numbers if enablePacketDebug=true, and throw an
      exception if packets received out-of-order.
    
    - Fixed BUG#4482, ResultSet.getObject() returns wrong type for strings
      when using prepared statements.
    
    - Calling MysqlPooledConnection.close() twice (even though an application
      error), caused NPE. Fixed.
    
    - Fixed BUG#5012 -- ServerPreparedStatements dealing with return of 
	  DECIMAL type don't work.
	  
	- Fixed BUG#5032 -- ResultSet.getObject() doesn't return 
      type Boolean for pseudo-bit types from prepared statements on 4.1.x
      (shortcut for avoiding extra type conversion when using binary-encoded
      result sets obscurred test in getObject() for 'pseudo' bit type)
      
    - You can now use URLs in 'LOAD DATA LOCAL INFILE' statements, and the
      driver will use Java's built-in handlers for retreiving the data and
      sending it to the server. This feature is not enabled by default, 
      you must set the 'allowUrlInLocalInfile' connection property to 'true'.
      
    - The driver is more strict about truncation of numerics on 
      ResultSet.get*(), and will throw a SQLException when truncation is
      detected. You can disable this by setting 'jdbcCompliantTruncation' to
      false (it is enabled by default, as this functionality is required
      for JDBC compliance).
      
    - Added three ways to deal with all-zero datetimes when reading them from
      a ResultSet, 'exception' (the default), which throws a SQLException 
      with a SQLState of 'S1009', 'convertToNull', which returns NULL instead of
      the date, and 'round', which rounds the date to the nearest closest value
      which is '0001-01-01'.
      
    - Fixed ServerPreparedStatement to read prepared statement metadata off 
      the wire, even though it's currently a placeholder instead of using
      MysqlIO.clearInputStream() which didn't work at various times because
      data wasn't available to read from the server yet. This fixes sporadic
      errors users were having with ServerPreparedStatements throwing 
      ArrayIndexOutOfBoundExceptions.
     
    - Use com.mysql.jdbc.Message's classloader when loading resource bundle,
      should fix sporadic issues when the caller's classloader can't locate
      the resource bundle.

07-07-04 - Version 3.1.3-beta
	
	- Mangle output parameter names for CallableStatements so they 
	  will not clash with user variable names.
	  
	- Added support for INOUT parameters in CallableStatements.
	
	- Fix for BUG#4119, null bitmask sent for server-side prepared
	  statements was incorrect.
	  
	- Use SQL Standard SQL states by default, unless 'useSqlStateCodes' 
	  property is set to 'false'.
	  
	- Added packet debuging code (see the 'enablePacketDebug' property
	  documentation).
	  
	- Added constants for MySQL error numbers (publicly-accessible,
	  see com.mysql.jdbc.MysqlErrorNumbers), and the ability to
	  generate the mappings of vendor error codes to SQLStates
	  that the driver uses (for documentation purposes).
	  
	- Externalized more messages (on-going effort).
	
	- Fix for BUG#4311 - Error in retrieval of mediumint column with
	  prepared statements and binary protocol.
	  
	- Support new timezone variables in MySQL-4.1.3 when 
	  'useTimezone=true'
	  
	- Support for unsigned numerics as return types from prepared statements.
	  This also causes a change in ResultSet.getObject() for the 'bigint unsigned'
	  type, which used to return BigDecimal instances, it now returns instances
	  of java.lang.BigInteger.
	   
06-09-04 - Version 3.1.2-alpha

	- Fixed stored procedure parameter parsing info when size was
	  specified for a parameter (i.e. char(), varchar()).
	  
	- Enabled callable statement caching via 'cacheCallableStmts'
	  property.
	  
	- Fixed case when no output parameters specified for a 
	  stored procedure caused a bogus query to be issued 
	  to retrieve out parameters, leading to a syntax error
	  from the server.
	  
	- Fixed case when no parameters could cause a NullPointerException
	  in CallableStatement.setOutputParameters().
	  	  
	- Removed wrapping of exceptions in MysqlIO.changeUser().
	
	- Fixed sending of split packets for large queries, enabled nio
	  ability to send large packets as well.
	  
	- Added .toString() functionality to ServerPreparedStatement,
	  which should help if you're trying to debug a query that is
	  a prepared statement (it shows SQL as the server would process).
	  
	- Added 'gatherPerformanceMetrics' property, along with properties
	  to control when/where this info gets logged (see docs for more 
	  info).
	  
	- ServerPreparedStatements weren't actually de-allocating
	  server-side resources when .close() was called.
	  
	- Added 'logSlowQueries' property, along with property 
	  'slowQueriesThresholdMillis' to control when a query should
	  be considered 'slow'.
	  
	- Correctly map output parameters to position given in
	  prepareCall() vs. order implied during registerOutParameter() -
	  fixes BUG#3146.
	  
	- Correctly detect initial character set for servers >= 4.1.0
	
	- Cleaned up detection of server properties. 
	
	- Support placeholder for parameter metadata for server >= 4.1.2
	
	- Fix for BUG#3539 getProcedures() does not return any procedures in 
	  result set
	
	- Fix for BUG#3540 getProcedureColumns() doesn't work with wildcards 
	  for procedure name
	  
	- Fixed BUG#3520 -- DBMD.getSQLStateType() returns incorrect value.
	
	- Added 'connectionCollation' property to cause driver to issue 
	  'set collation_connection=...' query on connection init if default
	  collation for given charset is not appropriate.
	  
	- Fixed DatabaseMetaData.getProcedures() when run on MySQL-5.0.0 (output of
	'show procedure status' changed between 5.0.1 and 5.0.0.
	
	- Fixed BUG#3804 -- getWarnings() returns SQLWarning instead of DataTruncation
	
	- Don't enable server-side prepared statements for server version 5.0.0 or 5.0.1,
	as they aren't compatible with the '4.1.2+' style that the driver uses (the driver
	expects information to come back that isn't there, so it hangs).
	
	  
02-14-04 - Version 3.1.1-alpha

    - Fixed bug with UpdatableResultSets not using client-side
	  prepared statements.
	  
	- Fixed character encoding issues when converting bytes to
	  ASCII when MySQL doesn't provide the character set, and
	  the JVM is set to a multibyte encoding (usually affecting
	  retrieval of numeric values).
	
	- Unpack 'unknown' data types from server prepared statements
	  as Strings.
	  
	- Implemented long data (Blobs, Clobs, InputStreams, Readers)
	  for server prepared statements.
	  
	- Implemented Statement.getWarnings() for MySQL-4.1 and newer
	  (using 'SHOW WARNINGS').

	  in com.mysql.jdbc.Connection.
	  
	- Reduced number of methods called in average query to be more
	  efficient.
	  
	- Prepared Statements will be re-prepared on auto-reconnect. Any errors
	  encountered are postponed until first attempt to re-execute the
	  re-prepared statement.
	  
	- Ensure that warnings are cleared before executing queries
	  on prepared statements, as-per JDBC spec (now that we support
	  warnings).
	 
	- Support 'old' profileSql capitalization in ConnectionProperties.
	  This property is deprecated, you should use 'profileSQL' if possible.
	  
	- Optimized Buffer.readLenByteArray() to return shared empty byte array 
	  when length is 0.
	 
	- Allow contents of PreparedStatement.setBlob() to be retained
	  between calls to .execute*().
	  
	- Deal with 0-length tokens in EscapeProcessor (caused by callable
	  statement escape syntax).
	  
	- Check for closed connection on delete/update/insert row operations in 
	  UpdatableResultSet.

	- Fixed stack overflow in Connection.prepareCall() (bad merge).
	
	- Fixed IllegalAccessError to Calendar.getTimeInMillis() in DateTimeValue
	  (for JDK < 1.4). 
	  
	- Fix for BUG#1673, where DatabaseMetaData.getColumns() is not
      returning correct column ordinal info for non '%' column name patterns.
      
    - Merged fix of datatype mapping from MySQL type 'FLOAT' to 
      java.sql.Types.REAL from 3.0 branch.
      
    - Detect collation of column for RSMD.isCaseSensitive().
    
    - Fixed sending of queries > 16M.
    
    - Added named and indexed input/output parameter support to CallableStatement.
      MySQL-5.0.x or newer.
      
    - Fixed NullPointerException in ServerPreparedStatement.setTimestamp(),
      as well as year and month descrepencies in 
      ServerPreparedStatement.setTimestamp(), setDate().
      
    - Added ability to have multiple database/JVM targets for compliance
      and regression/unit tests in build.xml.
      
    - Fixed NPE and year/month bad conversions when accessing some 
      datetime functionality in ServerPreparedStatements and their 
      resultant result sets.
      
    - Display where/why a connection was implicitly closed (to
      aid debugging).
      
    - CommunicationsException implemented, that tries to determine
      why communications was lost with a server, and displays
      possible reasons when .getMessage() is called.
      
    - Fixed BUG#2359, NULL values for numeric types in binary
      encoded result sets causing NullPointerExceptions.
      
    - Implemented Connection.prepareCall(), and DatabaseMetaData.
      getProcedures() and getProcedureColumns().
      
    - Reset 'long binary' parameters in ServerPreparedStatement when
      clearParameters() is called, by sending COM_RESET_STMT to the 
      server.
      
    - Merged prepared statement caching, and .getMetaData() support
      from 3.0 branch.
    
    - Fixed off-by-1900 error in some cases for 
      years in TimeUtil.fastDate/TimeCreate() when unpacking results
      from server-side prepared statements.

02-18-03 - Version 3.1.0-alpha

    - Added 'requireSSL' property.
    
    - Added 'useServerPrepStmts' property (default 'false'). The
      driver will use server-side prepared statements when the
      server version supports them (4.1 and newer) when this
      property is set to 'true'. It is currently set to 'false' 
      by default until all bind/fetch functionality has been 
      implemented. Currently only DML prepared statements are
      implemented for 4.1 server-side prepared statements.
  
    - Track open Statements, close all when Connection.close()
      is called (JDBC compliance).

06-22-05 - Version 3.0.17-ga
    
    - Fixed BUG#5874, Timestamp/Time conversion goes in the wrong 'direction' 
      when useTimeZone='true' and server timezone differs from client timezone.
	
	- Fixed BUG#7081, DatabaseMetaData.getIndexInfo() ignoring 'unique' 
	  parameter.
	
	- Support new protocol type 'MYSQL_TYPE_VARCHAR'.
	
	- Added 'useOldUTF8Behavoior' configuration property, which causes
	  JDBC driver to act like it did with MySQL-4.0.x and earlier when
	  the character encoding is 'utf-8' when connected to MySQL-4.1 or 
	  newer.
	
	- Fixed BUG#7316 - Statements created from a pooled connection were
	  returning physical connection instead of logical connection when
	  getConnection() was called.
	  
	- Fixed BUG#7033 - PreparedStatements don't encode Big5 (and other 
	  multibyte) character sets correctly in static SQL strings.
	  
	- Fixed BUG#6966, connections starting up failed-over (due to down master)
      never retry master.
      
    - Fixed BUG#7061, PreparedStatement.fixDecimalExponent() adding extra 
      '+', making number unparseable by MySQL server.

    - Fixed BUG#7686, Timestamp key column data needed "_binary'" stripped for 
      UpdatableResultSet.refreshRow().
    
    - Backported SQLState codes mapping from Connector/J 3.1, enable with
      'useSqlStateCodes=true' as a connection property, it defaults to
      'false' in this release, so that we don't break legacy applications (it
      defaults to 'true' starting with Connector/J 3.1).
      
    - Fixed BUG#7601, PreparedStatement.fixDecimalExponent() adding extra 
      '+', making number unparseable by MySQL server.
      
    - Escape sequence {fn convert(..., type)} now supports ODBC-style types
      that are prepended by 'SQL_'.
    
    - Fixed duplicated code in configureClientCharset() that prevented
      useOldUTF8Behavior=true from working properly.
    
    - Handle streaming result sets with > 2 billion rows properly by fixing
      wraparound of row number counter.
    
    - Fixed BUG#7607 - MS932, SHIFT_JIS and Windows_31J not recog. as 
      aliases for sjis.
    
    - Fixed BUG#6549 (while fixing #7607), adding 'CP943' to aliases for
      sjis.
    
    - Fixed BUG#8064, which requires hex escaping of binary data when using
      multibyte charsets with prepared statements.
      
    - Fixed BUG#8812, NON_UNIQUE column from DBMD.getIndexInfo() returned 
      inverted value.
      
    - Workaround for server BUG#9098 - default values of CURRENT_* for 
      DATE/TIME/TIMESTAMP/TIMESTAMP columns can't be distinguished from
      'string' values, so UpdatableResultSet.moveToInsertRow() generates
      bad SQL for inserting default values.
      
    - Fixed BUG#8629 - 'EUCKR' charset is sent as 'SET NAMES euc_kr' which
      MySQL-4.1 and newer doesn't understand.
      
    - DatabaseMetaData.supportsSelectForUpdate() returns correct value based
      on server version.
      
    - Use hex escapes for PreparedStatement.setBytes() for double-byte charsets
      including 'aliases' Windows-31J, CP934, MS932.
      
    - Added support for the "EUC_JP_Solaris" character encoding, which maps
      to a MySQL encoding of "eucjpms" (backported from 3.1 branch). This only
      works on servers that support eucjpms, namely 5.0.3 or later.

11-15-04 - Version 3.0.16-ga

	- Re-issue character set configuration commands when re-using pooled
	  connections and/or Connection.changeUser() when connected to MySQL-4.1
	  or newer.
	  
	- Fixed ResultSetMetaData.isReadOnly() to detect non-writable columns
	  when connected to MySQL-4.1 or newer, based on existence of 'original'
	  table and column names.
	  
	- Fixed BUG#5664, ResultSet.updateByte() when on insert row
      throws ArrayOutOfBoundsException.
      
    - Fixed DatabaseMetaData.getTypes() returning incorrect (i.e. non-negative)
      scale for the 'NUMERIC' type.
      
    - Fixed BUG#6198, off-by-one bug in Buffer.readString(string).
    
    - Made TINYINT(1) -> BIT/Boolean conversion configurable via 'tinyInt1isBit'
      property (default 'true' to be JDBC compliant out of the box).
      
    - Only set 'character_set_results' during connection establishment if
      server version >= 4.1.1.
      
    - Fixed regression where useUnbufferedInput was defaulting to 'false'.
    
    - Fixed BUG#6231, ResultSet.getTimestamp() on a column with TIME in it
      fails.
      
09-04-04 - Version 3.0.15-ga

	- Fixed BUG#4010 - StringUtils.escapeEasternUnicodeByteStream is still
	  broken for GBK
	  
	- Fixed BUG#4334 - Failover for autoReconnect not using port #'s for any
	  hosts, and not retrying all hosts. (WARN: This required a change to 
	  the SocketFactory connect() method signature, which is now
	  
	    public Socket connect(String host, int portNumber, Properties props),
	  
	  therefore any third-party socket factories will have to be changed
	  to support this signature.
	  
	- Logical connections created by MysqlConnectionPoolDataSource will
	  now issue a rollback() when they are closed and sent back to the pool.
	  If your application server/connection pool already does this for you, you 
	  can set the 'rollbackOnPooledClose' property to false to avoid the
	  overhead of an extra rollback().
	 
	- Removed redundant calls to checkRowPos() in ResultSet.
	
	- Fixed BUG#4742, 'DOUBLE' mapped twice in DBMD.getTypeInfo().

	- Added FLOSS license exemption.
	
	- Fixed BUG#4808, calling .close() twice on a PooledConnection causes NPE.
	
	- Fixed BUG#4138 and BUG#4860, DBMD.getColumns() returns incorrect JDBC 
	  type for unsigned columns. This affects type mappings for all numeric 
	  types in the RSMD.getColumnType() and RSMD.getColumnTypeNames() methods 
	  as well, to ensure that 'like' types from DBMD.getColumns() match up 
	  with what RSMD.getColumnType() and getColumnTypeNames() return.
	  
	- 'Production' - 'GA' in naming scheme of distributions.
	
	- Fix for BUG#4880, RSMD.getPrecision() returning 0 for non-numeric types
	  (should return max length in chars for non-binary types, max length
	  in bytes for binary types). This fix also fixes mapping of 
	  RSMD.getColumnType() and RSMD.getColumnTypeName() for the BLOB types based
	  on the length sent from the server (the server doesn't distinguish between
	  TINYBLOB, BLOB, MEDIUMBLOB or LONGBLOB at the network protocol level).
	  
	- Fixed BUG#5022 - ResultSet should release Field[] instance in .close().
	       
    - Fixed BUG#5069 -- ResultSet.getMetaData() should not return 
	  incorrectly-initialized metadata if the result set has been closed, but 
	  should instead throw a SQLException. Also fixed for getRow() and 
	  getWarnings() and traversal methods by calling checkClosed() before
	  operating on instance-level fields that are nullified during .close().
	  
	- Parse new timezone variables from 4.1.x servers.
	
	- Use _binary introducer for PreparedStatement.setBytes() and 
	  set*Stream() when connected to MySQL-4.1.x or newer to avoid 
	  misinterpretation during character conversion.
	  
05-28-04 - Version 3.0.14-production

	- Fixed URL parsing error
	
05-27-04 - Version 3.0.13-production

	- Fixed BUG#3848 - Using a MySQLDatasource without server name fails
	
	- Fixed BUG#3920 - "No Database Selected" when using 
	  MysqlConnectionPoolDataSource.
	  
	- Fixed BUG#3873 - PreparedStatement.getGeneratedKeys() method returns only 
	  1 result for batched insertions
	  
05-18-04 - Version 3.0.12-production

	- Add unsigned attribute to DatabaseMetaData.getColumns() output
	  in the TYPE_NAME column.
	  
	- Added 'failOverReadOnly' property, to allow end-user to configure
	  state of connection (read-only/writable) when failed over.
	  
	- Backported 'change user' and 'reset server state' functionality
      from 3.1 branch, to allow clients of MysqlConnectionPoolDataSource
      to reset server state on getConnection() on a pooled connection.
      
    - Don't escape SJIS/GBK/BIG5 when using MySQL-4.1 or newer.
    
    - Allow 'url' parameter for MysqlDataSource and MysqlConnectionPool
      DataSource so that passing of other properties is possible from
      inside appservers.
      
    - Map duplicate key and foreign key errors to SQLState of
      '23000'.
      
    - Backport documentation tooling from 3.1 branch.
    
    - Return creating statement for ResultSets created by
      getGeneratedKeys() (BUG#2957)
      
    - Allow java.util.Date to be sent in as parameter to
      PreparedStatement.setObject(), converting it to a Timestamp
      to maintain full precision (BUG#3103).
      
    - Don't truncate BLOBs/CLOBs when using setBytes() and/or
      setBinary/CharacterStream() (BUG#2670).
      
    - Dynamically configure character set mappings for field-level
      character sets on MySQL-4.1.0 and newer using 'SHOW COLLATION'
      when connecting.
      
    - Map 'binary' character set to 'US-ASCII' to support DATETIME
      charset recognition for servers >= 4.1.2
      
    - Use 'SET character_set_results" during initialization to allow any 
      charset to be returned to the driver for result sets.
      
    - Use charsetnr returned during connect to encode queries before
      issuing 'SET NAMES' on MySQL >= 4.1.0.
      
    - Add helper methods to ResultSetMetaData (getColumnCharacterEncoding()
      and getColumnCharacterSet()) to allow end-users to see what charset
      the driver thinks it should be using for the column.
      
    - Only set character_set_results for MySQL >= 4.1.0.
    
    - Fixed BUG#3511, StringUtils.escapeSJISByteStream() not covering all
      eastern double-byte charsets correctly.
      
    - Renamed StringUtils.escapeSJISByteStream() to more appropriate
      escapeEasternUnicodeByteStream().
      
    - Fixed BUG#3554 - Not specifying database in URL caused MalformedURL
      exception.
      
    - Auto-convert MySQL encoding names to Java encoding names if used
      for characterEncoding property.
      
    - Added encoding names that are recognized on some JVMs to fix case
      where they were reverse-mapped to MySQL encoding names incorrectly.
      
    - Use junit.textui.TestRunner for all unit tests (to allow them to be
      run from the command line outside of Ant or Eclipse).
      
    - Fixed BUG#3557 - UpdatableResultSet not picking up default values
      for moveToInsertRow().
      
    - Fixed BUG#3570 - inconsistent reporting of column type. The server
      still doesn't return all types for *BLOBs *TEXT correctly, so the
      driver won't return those correctly.
      
    - Fixed BUG#3520 -- DBMD.getSQLStateType() returns incorrect value.
    
    - Fixed regression in PreparedStatement.setString() and eastern character
      encodings.
      
    - Made StringRegressionTest 4.1-unicode aware.

02-19-04 - Version 3.0.11-stable

	- Trigger a 'SET NAMES utf8' when encoding is forced to 'utf8' _or_
	  'utf-8' via the 'characterEncoding' property. Previously, only the
	  Java-style encoding name of 'utf-8' would trigger this.
	  
	- AutoReconnect time was growing faster than exponentially (BUG#2447).
	
	- Fixed failover always going to last host in list (BUG#2578)
	
	- Added 'useUnbufferedInput' parameter, and now use it by default
	  (due to JVM issue 
	  http://developer.java.sun.com/developer/bugParade/bugs/4401235.html)
	  
	- Detect 'on/off' or '1','2','3' form of lower_case_table_names on 
	  server.
	  
	- Return 'java.lang.Integer' for TINYINT and SMALLINT types from
	  ResultSetMetaData.getColumnClassName() (fix for BUG#2852).
	  
	- Return 'java.lang.Double' for FLOAT type from ResultSetMetaData.
	  getColumnClassName() (fix for BUG#2855).
	  
	- Return '[B' instead of java.lang.Object for BINARY, VARBINARY and 
	  LONGVARBINARY types from ResultSetMetaData.getColumnClassName() 
	  (JDBC compliance).
	  
01-13-04 - Version 3.0.10-stable

    - Don't count quoted id's when inside a 'string' in PreparedStatement
      parsing (fix for BUG#1511).
      
    - 'Friendlier' exception message for PacketTooLargeException
       (BUG#1534).

    - Fix for BUG#1775 - DatabaseMetaData.getSystemFunction() returning 
      bad function 'VResultsSion'.
      
    - Fix for BUG#1592 -- cross-database updatable result sets
      are not checked for updatability correctly.
      
    - DatabaseMetaData.getColumns() should return Types.LONGVARCHAR for
      MySQL LONGTEXT type.
      
    - ResultSet.getObject() on TINYINT and SMALLINT columns should return 
      Java type 'Integer' (BUG#1913)
      
    - Added 'alwaysClearStream' connection property, which causes the driver
      to always empty any remaining data on the input stream before
      each query.
      
    - Added more descriptive error message 'Server Configuration Denies 
      Access to DataSource', as well as retrieval of message from server.

      PreparedStatement.setTimestamp().
      
    - Removed static synchronization bottleneck from instance factory 
      method of SingleByteCharsetConverter.

      the 'cachePrepStmts', 'prepStmtCacheSize' and 'prepStmtCacheSqlLimit'
      properties (disabled by default).
      
    - Speed up parsing of PreparedStatements, try to use one-pass whenever
      possible.
      
    - Fixed security exception when used in Applets (applets can't
      read the system property 'file.encoding' which is needed
      for LOAD DATA LOCAL INFILE).

10-07-03 - Version 3.0.9-stable

	- Faster date handling code in ResultSet and PreparedStatement (no longer
	  uses Date methods that synchronize on static calendars).
	
	- Fixed test for end of buffer in Buffer.readString().
	
	- Fixed ResultSet.previous() behavior to move current 
	  position to before result set when on first row
	  of result set (bugs.mysql.com BUG#496)
	
	- Fixed Statement and PreparedStatement issuing bogus queries
	  when setMaxRows() had been used and a LIMIT clause was present
	  in the query.
	
	- Fixed BUG#661 - refreshRow didn't work when primary key values
	  contained values that needed to be escaped (they ended up being
	  doubly-escaped).
	
	- Support InnoDB contraint names when extracting foreign key info
	  in DatabaseMetaData BUG#517 and BUG#664
	  (impl. ideas from Parwinder Sekhon)
	
	- Backported 4.1 protocol changes from 3.1 branch (server-side SQL
	  states, new field info, larger client capability flags, 
	  connect-with-database, etc).
	
	- Fix UpdatableResultSet to return values for getXXX() when on
	  insert row (BUG#675).
	
	- The insertRow in an UpdatableResultSet is now loaded with 
	  the default column values when moveToInsertRow() is called
	  (BUG#688)
	
	- DatabaseMetaData.getColumns() wasn't returning NULL for 
	  default values that are specified as NULL.
	
	- Change default statement type/concurrency to TYPE_FORWARD_ONLY
	  and CONCUR_READ_ONLY (spec compliance).
	
	- Don't try and reset isolation level on reconnect if MySQL doesn't
	  support them.
	
	- Don't wrap SQLExceptions in RowDataDynamic.
	
	- Don't change timestamp TZ twice if useTimezone==true (BUG#774)
	
	- Fixed regression in large split-packet handling (BUG#848).
	
	- Better diagnostic error messages in exceptions for 'streaming'
	  result sets.
	
	- Issue exception on ResultSet.getXXX() on empty result set (wasn't
	  caught in some cases).
	
	- Don't hide messages from exceptions thrown in I/O layers.
	
	- Don't fire connection closed events when closing pooled connections, or
	  on PooledConnection.getConnection() with already open connections (BUG#884).
	
	- Clip +/- INF (to smallest and largest representative values for the type in 
	  MySQL) and NaN (to 0) for setDouble/setFloat(), and issue a warning on the
	  statement when the server does not support +/- INF or NaN.
	  
	- Fix for BUG#879, double-escaping of '\' when charset is SJIS or GBK and '\'
	  appears in non-escaped input.
	  
	- When emptying input stream of unused rows for 'streaming' result sets,
	  have the current thread yield() every 100 rows in order to not monopolize 
	  CPU time.
	  
	- Fixed BUG#1099, DatabaseMetaData.getColumns() getting confused about the
	  keyword 'set' in character columns.
	  
	- Fixed deadlock issue with Statement.setMaxRows().
	
	- Fixed CLOB.truncate(), BUG#1130
	
	- Optimized CLOB.setChracterStream(), BUG#1131
	
	- Made databaseName, portNumber and serverName optional parameters
	  for MysqlDataSourceFactory (BUG#1246)
	  
	- Fix for BUG#1247 -- ResultSet.get/setString mashing char 127
	
	- Backported auth. changes for 4.1.1 and newer from 3.1 branch. 
	
	- Added com.mysql.jdbc.util.BaseBugReport to help creation of testcases
	  for bug reports.
	  
	- Added property to 'clobber' streaming results, by setting the 
	  'clobberStreamingResults' property to 'true' (the default is 'false'). 
	  This will cause a 'streaming' ResultSet to be automatically
	  closed, and any oustanding data still streaming from the server to
	  be discarded if another query is executed before all the data has been
	  read from the server.

    - Fixed StringIndexOutOfBoundsException in PreparedStatement.
      setClob().
      
    - 4.1 Column Metadata fixes
    
    - Remove synchronization from Driver.connect() and 
      Driver.acceptsUrl().
      
    - IOExceptions during a transaction now cause the Connection to 
      be closed.
      
    - Fixed missing conversion for 'YEAR' type in ResultSetMetaData.
      getColumnTypeName().
      
    - Don't pick up indexes that start with 'pri' as primary keys
      for DBMD.getPrimaryKeys().
      
    - Throw SQLExceptions when trying to do operations on a forcefully
      closed Connection (i.e. when a communication link failure occurs).
      
    - You can now toggle profiling on/off using 
      Connection.setProfileSql(boolean).
      
    - Fixed charset issues with database metadata (charset was not
      getting set correctly).
      
    - Updatable ResultSets can now be created for aliased tables/columns

02-18-03 - Version 3.0.6-stable

    - Fixed ResultSetMetaData to return "" when catalog not known.
      Fixes NullPointerExceptions with Sun's CachedRowSet.
      
    - Fixed DBMD.getTypeInfo() and DBMD.getColumns() returning 
      different value for precision in TEXT/BLOB types.
      
    - Allow ignoring of warning for 'non transactional tables' during
      rollback (compliance/usability) by setting 'ignoreNonTxTables'
      property to 'true'.
      
    - Fixed SQLExceptions getting swallowed on initial connect.
    
    - Fixed Statement.setMaxRows() to stop sending 'LIMIT' type queries
      when not needed (performance)
      
    - Clean up Statement query/method mismatch tests (i.e. INSERT not
      allowed with .executeQuery()).
      
    - More checks added in ResultSet traversal method to catch
      when in closed state.
      
    - Fixed ResultSetMetaData.isWritable() to return correct value.
    
    - Add 'window' of different NULL sorting behavior to 
      DBMD.nullsAreSortedAtStart (4.0.2 to 4.0.10, true, otherwise,
      no).
      
    - Implemented Blob.setBytes(). You still need to pass the 
      resultant Blob back into an updatable ResultSet or
      PreparedStatement to persist the changes, as MySQL does
      not support 'locators'.
      
    - Backported 4.1 charset field info changes from Connector/J 3.1
      
01-22-03 - Version 3.0.5-gamma

    - Fixed Buffer.fastSkipLenString() causing ArrayIndexOutOfBounds
      exceptions with some queries when unpacking fields.
      
    - Implemented an empty TypeMap for Connection.getTypeMap() so that
      some third-party apps work with MySQL (IBM WebSphere 5.0 Connection
      pool).
      
    - Added missing LONGTEXT type to DBMD.getColumns().
    
    - Retrieve TX_ISOLATION from database for 
      Connection.getTransactionIsolation() when the MySQL version 
      supports it, instead of an instance variable.
      
    - Quote table names in DatabaseMetaData.getColumns(),
      getPrimaryKeys(), getIndexInfo(), getBestRowIdentifier()
      
    - Greatly reduce memory required for setBinaryStream() in
      PreparedStatements.
      
    - Fixed ResultSet.isBeforeFirst() for empty result sets.
    
    - Added update options for foreign key metadata.
    
      
01-06-03 - Version 3.0.4-gamma

      PreparedStatements for setByte().
      
    - Reduce memory footprint of PreparedStatements by sharing 
      outbound packet with MysqlIO.
      
    - Added 'strictUpdates' property to allow control of amount
      of checking for 'correctness' of updatable result sets. Set this
      to 'false' if you want faster updatable result sets and you know
      that you create them from SELECTs on tables with primary keys and
      that you have selected all primary keys in your query.
      
    - Added support for 4.0.8-style large packets. 
    
    - Fixed PreparedStatement.executeBatch() parameter overwriting.
	  
12-17-02 - Version 3.0.3-dev

    - Implemented Connection.nativeSQL()
    
    - More robust escape tokenizer -- recognize '--' comments, and allow
      nested escape sequences (see testsuite.EscapeProcessingTest)
      
    - DBMD.getImported/ExportedKeys() now handles multiple foreign keys 
      per table.
      
    - Fixed ResultSetMetaData.getPrecision() returning incorrect values 
      for some floating point types.
      
    - Fixed ResultSetMetaData.getColumnTypeName() returning BLOB for 
      TEXT and TEXT for BLOB types.
      
    - Fixed Buffer.isLastDataPacket() for 4.1 and newer servers.
    
    - Added CLIENT_LONG_FLAG to be able to get more column flags 
      (isAutoIncrement() being the most important)
      
    - Because of above, implemented ResultSetMetaData.isAutoIncrement()
      to use Field.isAutoIncrement().
      
    - Honor 'lower_case_table_names' when enabled in the server when
      doing table name comparisons in DatabaseMetaData methods.
      
    - Some MySQL-4.1 protocol support (extended field info from selects)
    
    - Use non-aliased table/column names and database names to fullly 
      qualify tables and columns in UpdatableResultSet (requires 
      MySQL-4.1 or newer)
      
    - Allow user to alter behavior of Statement/
      PreparedStatement.executeBatch() via 'continueBatchOnError' property
      (defaults to 'true').
      
    - Check for connection closed in more Connection methods 
      (createStatement, prepareStatement, setTransactionIsolation,
      setAutoCommit).
      
    - More robust implementation of updatable result sets. Checks that
      _all_ primary keys of the table have been selected.
      
    - 'LOAD DATA LOCAL INFILE ...' now works, if your server is configured
      to allow it. Can be turned off with the 'allowLoadLocalInfile' 
      property (see the README).
      
    - Substitute '?' for unknown character conversions in single-byte
      character sets instead of '\0'.
      
    - NamedPipeSocketFactory now works (only intended for Windows), see
      README for instructions.
	  
11-08-02 - Version 3.0.2-dev

    - Fixed issue when calling Statement.setFetchSize() when using 
      arbitrary values
      
    - Fixed incorrect conversion in ResultSet.getLong()
    
    - Implemented ResultSet.updateBlob().
    
    - Removed duplicate code from UpdatableResultSet (it can be inherited 
      from ResultSet, the extra code for each method to handle updatability
      I thought might someday be necessary has not been needed).
      
    - Fixed "UnsupportedEncodingException" thrown when "forcing" a 
      character encoding via properties.
      
    - Fixed various non-ASCII character encoding issues.
    
    - Added driver property 'useHostsInPrivileges'. Defaults to true. 
      Affects whether or not '@hostname' will be used in 
      DBMD.getColumn/TablePrivileges.
      
    - All DBMD result set columns describing schemas now return NULL
      to be more compliant with the behavior of other JDBC drivers
      for other databases (MySQL does not support schemas).
      
    - Added SSL support. See README for information on how to use it.
    
    - Properly restore connection properties when autoReconnecting
      or failing-over, including autoCommit state, and isolation level.
      
    - Use 'SHOW CREATE TABLE' when possible for determining foreign key
      information for DatabaseMetaData...also allows cascade options for
      DELETE information to be returned
      
    - Escape 0x5c character in strings for the SJIS charset.
    
    - Fixed start position off-by-1 error in Clob.getSubString()

      'shutdown' command to MySQL server...Intended to be used when 'embedding'
      Java and MySQL server together in an end-user application.
      
    - Added 'connectTimeout' parameter that allows users of JDK-1.4 and newer
      to specify a maxium time to wait to establish a connection.
      
    - Failover and autoReconnect only work when the connection is in a 
      autoCommit(false) state, in order to stay transaction safe
      
    - Added 'queriesBeforeRetryMaster' property that specifies how many
      queries to issue when failed over before attempting to reconnect 
      to the master (defaults to 50)
      
    - Fixed DBMD.supportsResultSetConcurrency() so that it returns true
      for ResultSet.TYPE_SCROLL_INSENSITIVE and ResultSet.CONCUR_READ_ONLY or
      ResultSet.CONCUR_UPDATABLE
      
    - Fixed ResultSet.isLast() for empty result sets (should return false).
    
    - PreparedStatement now honors stream lengths in setBinary/Ascii/Character
      Stream() unless you set the connection property 
      'useStreamLengthsInPrepStmts' to 'false'.
      
    - Removed some not-needed temporary object creation by using Strings
      smarter in EscapeProcessor, Connection and DatabaseMetaData classes.
         	
09-21-02 - Version 3.0.1-dev
	
    - Fixed ResultSet.getRow() off-by-one bug.
    
    - Fixed RowDataStatic.getAt() off-by-one bug.
    
    - Added limited Clob functionality (ResultSet.getClob(),
      PreparedStatemtent.setClob(), 
      PreparedStatement.setObject(Clob).
      
    - Added socketTimeout parameter to URL.
    
    - Connection.isClosed() no longer "pings" the server.
    
    - Connection.close() issues rollback() when getAutoCommit() == false
    
    - Added "paranoid" parameter...sanitizes error messages removing
      "sensitive" information from them (i.e. hostnames, ports,
      usernames, etc.), as well as clearing "sensitive" data structures
      when possible.
      
    - Fixed ResultSetMetaData.isSigned() for TINYINT and BIGINT.
    
    - Charsets now automatically detected. Optimized code for single-byte
      character set conversion.
      
    - Implemented ResultSet.getCharacterStream()
    
    - Added "LOCAL TEMPORARY" to table types in DatabaseMetaData.getTableTypes()
    
    - Massive code clean-up to follow Java coding conventions (the time had come)
  
	
07-31-02 - Version 3.0.0-dev

    - !!! LICENSE CHANGE !!! The driver is now GPL. If you need
      non-GPL licenses, please contact me <mark@mysql.com>
      
    - JDBC-3.0 functionality including 
      Statement/PreparedStatement.getGeneratedKeys() and

    - ResultSet.getTimestamp() now works for DATE types (SF bug 559134)
    
    - ResultSet.getDate/Time/Timestamp now recognizes all forms of invalid
      values that have been set to all zeroes by MySQL (SF bug 586058)

    - More code cleanup
    
    - PreparedStatement now releases resources on .close() (SF bug 553268)
    
    - Quoted identifiers not used if server version does not support them. Also,
      if server started with --ansi or --sql-mode=ANSI_QUOTES then '"' will be 
      used as an identifier quote, otherwise '`' will be used.
      
    - ResultSet.getDouble() now uses code built into JDK to be more precise (but slower)
    
    - LogicalHandle.isClosed() calls through to physical connection

    - PreparedStatement.toString() fixed (SF bug 534026)
    
    - ResultSetMetaData.getColumnClassName() now implemented
    
    - Rudimentary version of Statement.getGeneratedKeys() from JDBC-3.0
      now implemented (you need to be using JDK-1.4 for this to work, I
      believe)
	  
    - DBMetaData.getIndexInfo() - bad PAGES fixed (SF BUG 542201)
	
04-07-02 - Version 2.0.12

    - General code cleanup. 
    
    - Added getIdleFor() method to Connection and MysqlLogicalHandle.
    
    - Relaxed synchronization in all classes, should fix 520615 and 520393.
    
    - Added getTable/ColumnPrivileges() to DBMD (fixes 484502).
    
    - Added new types to getTypeInfo(), fixed existing types thanks to
      Al Davis and Kid Kalanon.

      if not updated).
      
    - DataSources - fixed setUrl bug (511614, 525565), 
      wrong datasource class name (532816, 528767)
      
    - Added identifier quoting to all DatabaseMetaData methods
      that need them (should fix 518108)
      
    - Added support for YEAR type (533556)
    
    - ResultSet.insertRow() should now detect auto_increment fields
      in most cases and use that value in the new row. This detection
      will not work in multi-valued keys, however, due to the fact that
      the MySQL protocol does not return this information.
      
    - ResultSet.refreshRow() implemented.
    
    - Fixed testsuite.Traversal afterLast() bug, thanks to Igor Lastric.
	
01-27-02 - Version 2.0.11

    - Fixed missing DELETE_RULE value in 
      DBMD.getImported/ExportedKeys() and getCrossReference().
      
    - Full synchronization of Statement.java.
    
    - More changes to fix "Unexpected end of input stream"
      errors when reading BLOBs. This should be the last fix.
       
01-24-02 - Version 2.0.10

     - Fixed spurious "Unexpected end of input stream" errors in 
       MysqlIO (bug 507456).
       
     - Fixed null-pointer-exceptions when using

     - Ant build was corrupting included jar files, fixed 
       (bug 487669).
       
     - Fixed extra memory allocation in MysqlIO.readPacket() 
       (bug 488663).
       
     - Implementation of DatabaseMetaData.getExported/ImportedKeys() and
       getCrossReference().
       
     - Full synchronization on methods modifying instance and class-shared
       references, driver should be entirely thread-safe now (please
       let me know if you have problems)
       
     - DataSource implementations moved to org.gjt.mm.mysql.jdbc2.optional
       package, and (initial) implementations of PooledConnectionDataSource
       and XADataSource are in place (thanks to Todd Wolff for the 
       implementation and testing of PooledConnectionDataSource with 
       IBM WebSphere 4).
       
     - Added detection of network connection being closed when reading packets
       (thanks to Todd Lizambri).
       
     - Fixed quoting error with escape processor (bug 486265).
     
     - Report batch update support through DatabaseMetaData (bug 495101).

       (bug 491577).
       
     - Removed concatenation support from driver (the '||' operator),
       as older versions of VisualAge seem to be the only thing that
       use it, and it conflicts with the logical '||' operator. You will
       need to start mysqld with the "--ansi" flag to use the '||' 
       operator as concatenation (bug 491680)
       
     - Fixed casting bug in PreparedStatement (bug 488663).
     
11-25-01 - Version 2.0.8

     - Batch updates now supported (thanks to some inspiration 
       from Daniel Rall).
       
     - XADataSource/ConnectionPoolDataSource code (experimental)
     
     - PreparedStatement.setAnyNumericType() now handles positive
       exponents correctly (adds "+" so MySQL can understand it).
       
     - DatabaseMetaData.getPrimaryKeys() and getBestRowIdentifier()
       are now more robust in identifying primary keys (matches 
       regardless of case or abbreviation/full spelling of Primary Key
       in Key_type column).
       
10-24-01 - Version 2.0.7

     - PreparedStatement.setCharacterStream() now implemented
         
     - Fixed dangling socket problem when in high availability

     - Fixed ResultSetMetaData.getPrecision() returning one
       less than actual on newer versions of MySQL.
       
     - ResultSet.getBlob() now returns null if column value
       was null.
       
     - Character sets read from database if useUnicode=true
       and characterEncoding is not set. (thanks to 
       Dmitry Vereshchagin)
       
     - Initial transaction isolation level read from 
       database (if avaialable) (thanks to Dmitry Vereshchagin)
       
     - Fixed DatabaseMetaData.supportsTransactions(), and
       supportsTransactionIsolationLevel() and getTypeInfo()
       SQL_DATETIME_SUB and SQL_DATA_TYPE fields not being
       readable.
        
     - Fixed PreparedStatement generating SQL that would end
       up with syntax errors for some queries.
       
     - Fixed ResultSet.isAfterLast() always returning false.
         
     - Fixed timezone issue in PreparedStatement.setTimestamp()
       (thanks to Erik Olofsson)
         
     - Captialize type names when "captializeTypeNames=true"
       is passed in URL or properties (for WebObjects, thanks
       to Anjo Krank)
         
     - Updatable result sets now correctly handle NULL
       values in fields.
       
     - PreparedStatement.setDouble() now uses full-precision
       doubles (reverting a fix made earlier to truncate them).
       
     - PreparedStatement.setBoolean() will use 1/0 for values
       if your MySQL Version >= 3.21.23.

       set (they will be set to "NULL")

     - DataBaseMetaData.getCrossReference() no longer ArrayIndexOOB

     - getObject() on ResultSet correctly does TINYINT->Byte and
       SMALLINT->Short

12-03-00 - Version 2.0.3

     - Implemented getBigDecimal() without scale component
       for JDBC2.

     - Fixed composite key problem with updateable result sets.

     - Added detection of -/+INF for doubles.

     - Faster ASCII string operations.

     - Fixed incorrect detection of MAX_ALLOWED_PACKET, so sending
       large blobs should work now.

     - Fixed off-by-one error in java.sql.Blob implementation code.

     - Added "ultraDevHack" URL parameter, set to "true" to allow 
       (broken) Macromedia UltraDev to use the driver.

04-06-00 - Version 2.0.1

     - Fixed RSMD.isWritable() returning wrong value. 
       Thanks to Moritz Maass.

     - Cleaned up exception handling when driver connects

     - Columns that are of type TEXT now return as Strings

     - No escape processing is done on PreparedStatements anymore
       per JDBC spec.

     - Fixed many JDBC-2.0 traversal, positioning bugs, especially
       wrt to empty result sets. Thanks to Ron Smits, Nick Brook,
       Cessar Garcia and Carlos Martinez.

     - Fixed some issues with updatability support in ResultSet when
       using multiple primary keys.

02-21-00 - Version 2.0pre5

     - Fixed Bad Handshake problem.

01-10-00 - Version 2.0pre4

     - Fixes to ResultSet for insertRow() - Thanks to
       Cesar Garcia

     - Fix to Driver to recognize JDBC-2.0 by loading a JDBC-2.0
       class, instead of relying on JDK version numbers. Thanks
       to John Baker.

     - Fixed ResultSet to return correct row numbers
     
     - Statement.getUpdateCount() now returns rows matched,
       instead of rows actually updated, which is more SQL-92
       like.

10-29-99 

     - Statement/PreparedStatement.getMoreResults() bug fixed. 
       Thanks to Noel J. Bergman.

     - Added Short as a type to PreparedStatement.setObject().
       Thanks to Jeff Crowder

     - Driver now automagically configures maximum/preferred packet
       sizes by querying server.

     - Autoreconnect code uses fast ping command if server supports
       it.

     - Fixed various bugs wrt. to packet sizing when reading from
       the server and when alloc'ing to write to the server.

08-17-99 - Version 2.0pre

     - Now compiles under JDK-1.2. The driver supports both JDK-1.1
       and JDK-1.2 at the same time through a core set of classes.
       The driver will load the appropriate interface classes at
       runtime by figuring out which JVM version you are using.

     - Fixes for result sets with all nulls in the first row.
       (Pointed out by Tim Endres)

     - Fixes to column numbers in SQLExceptions in ResultSet
       (Thanks to Blas Rodriguez Somoza)

     - The database no longer needs to specified to connect.
       (Thanks to Christian Motschke)

07-04-99 - Version 1.2b

     - Better Documentation (in progress), in doc/mm.doc/book1.html

     - DBMD now allows null for a column name pattern (not in 
       spec), which it changes to '%'.

     - DBMD now has correct types/lengths for getXXX().

     - ResultSet.getDate(), getTime(), and getTimestamp() fixes. 
       (contributed by Alan Wilken)

     - EscapeProcessor now handles \{ \} and { or } inside quotes
       correctly. (thanks to Alik for some ideas on how to fix it)

     - Fixes to properties handling in Connection.
       (contributed by Juho Tikkala)

     - ResultSet.getObject() now returns null for NULL columns
       in the table, rather than bombing out.
       (thanks to Ben Grosman)

     - ResultSet.getObject() now returns Strings for types
       from MySQL that it doesn't know about. (Suggested by
       Chris Perdue)

     - Removed DataInput/Output streams, not needed, 1/2 number
       of method calls per IO operation.

     - Use default character encoding if one is not specified. This
       is a work-around for broken JVMs, because according to spec,
       EVERY JVM must support "ISO8859_1", but they don't.

     - Fixed Connection to use the platform character encoding
       instead of "ISO8859_1" if one isn't explicitly set. This 
       fixes problems people were having loading the character-
       converter classes that didn't always exist (JVM bug).
       (thanks to Fritz Elfert for pointing out this problem)

     - Changed MysqlIO to re-use packets where possible to reduce
       memory usage.

     - Fixed escape-processor bugs pertaining to {} inside
       quotes.

04-14-99 - Version 1.2a

     - Fixed character-set support for non-Javasoft JVMs
       (thanks to many people for pointing it out)

     - Fixed ResultSet.getBoolean() to recognize 'y' & 'n'
       as well as '1' & '0' as boolean flags.
       (thanks to Tim Pizey)

     - Fixed ResultSet.getTimestamp() to give better performance.
       (thanks to Richard Swift)

     - Fixed getByte() for numeric types.
       (thanks to Ray Bellis)

     - Fixed DatabaseMetaData.getTypeInfo() for DATE type.
       (thanks to Paul Johnston)

     - Fixed EscapeProcessor for "fn" calls.
       (thanks to Piyush Shah at locomotive.org)

     - Fixed EscapeProcessor to not do extraneous work if there
       are no escape codes.
       (thanks to Ryan Gustafson)

     - Fixed Driver to parse URLs of the form "jdbc:mysql://host:port"
       (thanks to Richard Lobb)

03-24-99 - Version 1.1i

     - Fixed Timestamps for PreparedStatements
    
     - Fixed null pointer exceptions in RSMD and RS

     - Re-compiled with jikes for valid class files (thanks ms!)

03-08-99 - Version 1.1h

     - Fixed escape processor to deal with un-matched { and }
       (thanks to Craig Coles)
       
     - Fixed escape processor to create more portable (between
       DATETIME and TIMESTAMP types) representations so that
       it will work with BETWEEN clauses.
       (thanks to Craig Longman)
       
     - MysqlIO.quit() now closes the socket connection. Before,
       after many failed connections some OS's would run out
       of file descriptors. (thanks to Michael Brinkman)
       
     - Fixed NullPointerException in Driver.getPropertyInfo.
       (thanks to Dave Potts)
        
     - Fixes to MysqlDefs to allow all *text fields to be
       retrieved as Strings.
       (thanks to Chris at Leverage)
       
     - Fixed setDouble in PreparedStatement for large numbers
       to avoid sending scientific notation to the database.
       (thanks to J.S. Ferguson)
       
     - Fixed getScale() and getPrecision() in RSMD.
       (contrib'd by James Klicman)
       
     - Fixed getObject() when field was DECIMAL or NUMERIC
       (thanks to Bert Hobbs)
       
     - DBMD.getTables() bombed when passed a null table-name
       pattern. Fixed. (thanks to Richard Lobb)
       
     - Added check for "client not authorized" errors during
       connect. (thanks to Hannes Wallnoefer)
       
02-19-99 - Version 1.1g

     - Result set rows are now byte arrays. Blobs and Unicode
       work bidriectonally now. The useUnicode and encoding
       options are implemented now.
       
     - Fixes to PreparedStatement to send binary set by
       setXXXStream to be sent un-touched to the MySQL server.
       
     - Fixes to getDriverPropertyInfo().
       
12-31-98 - Version 1.1f

     - Changed all ResultSet fields to Strings, this should allow
       Unicode to work, but your JVM must be able to convert
       between the character sets. This should also make reading
       data from the server be a bit quicker, because there is now
       no conversion from StringBuffer to String.

     - Changed PreparedStatement.streamToString() to be more
       efficient (code from Uwe Schaefer).

     - URL parsing is more robust (throws SQL exceptions on errors
       rather than NullPointerExceptions)

     - PreparedStatement now can convert Strings to Time/Date values
       via setObject() (code from Robert Currey).

     - IO no longer hangs in Buffer.readInt(), that bug was
       introduced in 1.1d when changing to all byte-arrays for
       result sets. (Pointed out by Samo Login)

11-03-98 - Version 1.1b 

     - Fixes to DatabaseMetaData to allow both IBM VA and J-Builder
       to work. Let me know how it goes. (thanks to Jac Kersing)

     - Fix to ResultSet.getBoolean() for NULL strings 
       (thanks to Barry Lagerweij)

     - Beginning of code cleanup, and formatting. Getting ready
       to branch this off to a parallel JDBC-2.0 source tree.

     - Added "final" modifier to critical sections in MysqlIO and
       Buffer to allow compiler to inline methods for speed.

9-29-98 

     - If object references passed to setXXX() in PreparedStatement are
       null, setNull() is automatically called for you. (Thanks for the
       suggestion goes to Erik Ostrom)

     - setObject() in PreparedStatement will now attempt to write a 
       serialized  representation of the object to the database for
       objects of Types.OTHER and objects of unknown type.

     - Util now has a static method readObject() which given a ResultSet
       and a column index will re-instantiate an object serialized in
       the above manner.

9-02-98 - Vesion 1.1

     - Got rid of "ugly hack" in MysqlIO.nextRow(). Rather than
       catch an exception, Buffer.isLastDataPacket() was fixed.
          
     - Connection.getCatalog() and Connection.setCatalog()
       should work now.

     - Statement.setMaxRows() works, as well as setting
       by property maxRows. Statement.setMaxRows() overrides
       maxRows set via properties or url parameters.

     - Automatic re-connection is available. Because it has
       to "ping" the database before each query, it is
       turned off by default. To use it, pass in "autoReconnect=true"
       in the connection URL. You may also change the number of
       reconnect tries, and the initial timeout value via 
       "maxReconnects=n" (default 3) and "initialTimeout=n" 
       (seconds, default 2) parameters. The timeout is an 
       exponential backoff type of timeout, e.g. if you have initial 
       timeout of 2 seconds, and maxReconnects of 3, then the driver
       will timeout 2 seconds, 4 seconds, then 16 seconds between each
       re-connection attempt.

8-24-98 - Version 1.0 

     - Fixed handling of blob data in Buffer.java
	
     - Fixed bug with authentication packet being
       sized too small.

     - The JDBC Driver is now under the LPGL
	
8-14-98 - 

     - Fixed Buffer.readLenString() to correctly
          read data for BLOBS.
          
     - Fixed PreparedStatement.stringToStream to
          correctly read data for BLOBS.
          
     - Fixed PreparedStatement.setDate() to not
       add a day.
       (above fixes thanks to Vincent Partington)
          
     - Added URL parameter parsing (?user=... etc).
      

8-04-98 - Version 0.9d

     - Big news! New package name. Tim Endres from ICE
       Engineering is starting a new source tree for
       GNU GPL'd Java software. He's graciously given
       me the org.gjt.mm package directory to use, so now 
       the driver is in the org.gjt.mm.mysql package scheme.
       I'm "legal" now. Look for more information on Tim's
       project soon.
          
     - Now using dynamically sized packets to reduce
       memory usage when sending commands to the DB.
          
     - Small fixes to getTypeInfo() for parameters, etc.
          
     - DatabaseMetaData is now fully implemented. Let me
       know if these drivers work with the various IDEs
       out there. I've heard that they're working with
       JBuilder right now.
          
     - Added JavaDoc documentation to the package.
          
     - Package now available in .zip or .tar.gz.
          
7-28-98 - Version 0.9

     - Implemented getTypeInfo(). 
       Connection.rollback() now throws an SQLException
       per the JDBC spec.
          
     - Added PreparedStatement that supports all JDBC API
       methods for PreparedStatement including InputStreams.
       Please check this out and let me know if anything is
       broken.
          
     - Fixed a bug in ResultSet that would break some
       queries that only returned 1 row.
          
     - Fixed bugs in DatabaseMetaData.getTables(), 
       DatabaseMetaData.getColumns() and
       DatabaseMetaData.getCatalogs().
          
     - Added functionality to Statement that allows
       executeUpdate() to store values for IDs that are
       automatically generated for AUTO_INCREMENT fields.
       Basically, after an executeUpdate(), look at the
       SQLWarnings for warnings like "LAST_INSERTED_ID =
       'some number', COMMAND = 'your SQL query'".
          
       If you are using AUTO_INCREMENT fields in your
       tables and are executing a lot of executeUpdate()s
       on one Statement, be sure to clearWarnings() every
       so often to save memory.

7-06-98 - Version 0.8

     - Split MysqlIO and Buffer to separate classes. Some
       ClassLoaders gave an IllegalAccess error for some
       fields in those two classes. Now mm.mysql works in 
       applets and all classloaders.

       Thanks to Joe Ennis <jce@mail.boone.com> for pointing
       out the problem and working on a fix with me.

7-01-98 - Version 0.7

     - Fixed DatabaseMetadata problems in getColumns() and
       bug in switch statement in the Field constructor.

       Thanks to Costin Manolache <costin@tdiinc.com> for 
       pointing these out.

5-21-98 - Version 0.6

     - Incorporated efficiency changes from 
       Richard Swift <Richard.Swift@kanatek.ca> in
       MysqlIO.java and ResultSet.java

     - We're now 15% faster than gwe's driver.

     - Started working on DatabaseMetaData.
          
       The following methods are implemented:
        * getTables() 
        * getTableTypes()
        * getColumns
        * getCatalogs()
