Timestamp key column data needed _binary stripped for UpdatableResultSet.refreshRow(). (Bug#7686)

Timestamps converted incorrectly to strings with server-side prepared statements and updatable result sets. (Bug#7715)

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).

Infinite recursion when „falling back“ to master in failover configuration. (Bug#7952)

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.

Emulated locators corrupt binary data when using server-side prepared statements. (Bug#8096)

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. You can disable this by passing emulateUnsupportedPstmts=false in your JDBC URL. (Bug#4718)

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 time zone 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 (that is, applications that don't close Statement objects when they should).

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

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

PreparedStatements not creating streaming result sets. (Bug#8487)

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

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. (Bug#8424)

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.
