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.
          com.mysql.jdbc.PreparedStatement.ParseInfo
          does unnecessary call to toCharArray().
          (Bug#9064)
        
          Memory leak in ServerPreparedStatement if
          serverPrepare() fails. (Bug#10144)
        
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.
        
          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. (Bug#10156)
        
Double quotes not recognized when parsing client-side prepared statements. (Bug#10155)
          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.
        
          Driver doesn't support {?=CALL(...)} for
          calling stored functions. This involved adding support for
          function retrieval to
          DatabaseMetaData.getProcedures() and
          getProcedureColumns() as well. (Bug#10310)
        
          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. (Bug#10485)
        
          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. Regardless 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.
        
          SQLException is thrown when using property
          characterSetResults with
          cp932 or eucjpms. (Bug#10496)
        
          Reorganized directory layout. Sources now are 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.
        
0-length streams not sent to server when using server-side prepared statements. (Bug#10850)
          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.
        
          VARBINARY data corrupted when using
          server-side prepared statements and
          ResultSet.getBytes(). (Bug#11115)
        
          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.
        
          autoReconnect ping causes exception on
          connection startup. (Bug#11259)
        
          Connector/J dumping query into SQLException
          twice. (Bug#11360)
        
          Fixed PreparedStatement.setClob() not
          accepting null as a parameter.
        
Production package doesn't include JBoss integration classes. (Bug#11411)
Removed nonsensical „costly type conversion“ warnings when using usage advisor.
