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#103).

Don't truncate BLOB or CLOB values 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.

StringUtils.escapeSJISByteStream() not covering all eastern double-byte charsets correctly. (Bug#3511)

Renamed StringUtils.escapeSJISByteStream() to more appropriate escapeEasternUnicodeByteStream().

Not specifying database in URL caused MalformedURL exception. (Bug#3554)

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).

UpdatableResultSet not picking up default values for moveToInsertRow(). (Bug#3557)

Inconsistent reporting of data type. The server still doesn't return all types for *BLOBs *TEXT correctly, so the driver won't return those correctly. (Bug#3570)

DBMD.getSQLStateType() returns incorrect value. (Bug#3520)

Fixed regression in PreparedStatement.setString() and eastern character encodings.

Made StringRegressionTest 4.1-unicode aware.
