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 multi-byte 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).

Default result set type changed to TYPE_FORWARD_ONLY (JDBC compliance).

Centralized setting of result set type and concurrency.

Refactored how connection properties are set and exposed as DriverPropertyInfo as well as Connection and DataSource properties.

Support for NIO. Use useNIO=true on platforms that support NIO.

Support for transaction savepoints (MySQL >= 4.0.14 or 4.1.1).

Support for mysql_change_user(). See the changeUser() method 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.

Fix support for table aliases when checking for all primary keys in UpdatableResultSet.

Removed useFastDates connection property.

Correctly initialize datasource properties from JNDI Refs, including explicitly specified URLs.

DatabaseMetaData now reports supportsStoredProcedures() for MySQL versions >= 5.0.0

Fixed stack overflow in Connection.prepareCall() (bad merge).

Fixed IllegalAccessError to Calendar.getTimeInMillis() in DateTimeValue (for JDK < 1.4).

DatabaseMetaData.getColumns() is not returning correct column ordinal info for non-'%' column name patterns. (Bug#1673)

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 larger than 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.

NULL values for numeric types in binary encoded result sets causing NullPointerExceptions. (Bug#2359)

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.

Fixed charset conversion issue in getTables(). (Bug#2502)

Implemented multiple result sets returned from a statement or stored procedure.

Server-side prepared statements were not returning datatype YEAR correctly. (Bug#2606)

Enabled streaming of result sets from server-side prepared statements.

Class-cast exception when using scrolling result sets and server-side prepared statements. (Bug#2623)

Merged unbuffered input code from 3.0.

Fixed ConnectionProperties that weren't properly exposed via accessors, cleaned up ConnectionProperties code.

NULL fields were not being encoded correctly in all cases in server-side prepared statements. (Bug#2671)

Fixed rare buffer underflow when writing numbers into buffers for sending prepared statement execution requests.

Use DocBook version of docs for shipped versions of drivers.
