It is basically a bug fix release to 3.51.03 with the following fixes or improvements:

* Support for handling large tables without caching the entire result set locally in the driver through the option 'Do not cache results'. Now one can force the driver to use non-cache result sets (mysql_use_result instead of mysql_store_result) in order to make the resultset query executes within no time. Note that this can be used only with forward-only cursors.
* Added '--enable-thread-safe' and '--disable-thread-safe' options to configure script, so that driver links directly with thread-safe or non thread-safe client libraries instead of using the explicit symbolic links.
* Fixed SQLTables to not to return any data related to SYSTEM TABLES due to the conflict of database names. This should allow 'WinSQL' and other ODBC tools to show the correct user tables without any duplicates.
* Fixed few core dumps from HP-UX and AIX.
* Fixed the segfault from SQLAllocHandle and SQLFreeHandle on AIX when using the thread-safe client (debug calls).
* Added in the driver to check for pre-connection attributes after the connection instead of returning an error (like AUTOCOMMIT, TXN_ISOLATION). Now if the server doesn't support any requests set prior to the connection, then the connection API SQLConnect / SQLDisconnect will return a warning.
* Portability changes for MySQL 4.0.3 and above, so that the driver compiles through all released versions of MySQL.
* Fix to SQLForeignKeys when the CREATE TABLE had a COMMENT syntax.
* Two new options 'Force use of forward-only cursors' and 'Don't cache results' to help large scale customers.
* Fix to rs.update when server side cursor is used.
* Changes for error handling w.r.t. MySQL 4.3.
* VB Multi-step generated error fixups.
* Improvements to driver logging calls (myodbc.log and myodbc.sql)
* Few misc portability changes to build the driver on various UNIX platforms
* Lot of code cleanup to have better performance:
