MySQL 3.23.53, the world's most popular Open Source Database, has been released. It is now available in source and binary form for a number of platforms from our download pages at http://www.mysql.com/downloads/ (http://www.mysql.com/downloads/) and mirror sites.

This is a bugfix release for the current product tree.

- From the changelog:

o Fixed crash when SHOW INNODB STATUS was used and skip-innodb was defined.
o Fixed possible memory corruption bug in binary log file handling when slave rotated the logs (only affected 3.23, not 4.0).
o Fixed problem in LOCK TABLES on windows when one connects to a database that contains upper case letters.
o Fixed that --skip-show-databases doesn't reset the --port option.
o Small fix in safe_mysqld for some shells.
o Fixed that FLUSH STATUS doesn't reset Delayed_insert_threads.
o Fixed core dump bug when using the BINARY cast on a NULL value.
o Fixed race condition when someone did a GRANT at the same time a new user logged in or did a USE DATABASE.
o Fixed bug in ALTER TABLE and RENAME TABLE when running with -O lower_case_table_names=1 (typically on windows) when giving the table name in uppercase.
o Fixed that -O lower_case_table_names=1 also converts database names to lower case.
o Fixed unlikely core dump with SELECT ... ORDER BY ... LIMIT.
o Changed AND/OR to report that they can return NULL. This fixes a bug in GROUP BY on AND/OR expressions that return NULL.
o Fixed a bug that OPTIMIZE of locked and modified MyISAM table, reported table corruption.
o Fixed a BDB-related ALTER TABLE bug with dropping a column and shutting down immediately thereafter.
o Fixed problem with configure ... --localstatedir=....
o Fixed problem with UNSIGNED BIGINT on AIX (again).
o Fixed bug in pthread_mutex_trylock() on HPUX 11.0.
o Multithreaded stress tests for InnoDB.

Additional notes regarding the binary packages:

- We've hopefully fixed the problem with spurious load spikes on Linux systems when accessing the Database via TCP/IP. This was caused by the static glibc files we used to link against and should now be resolved.
- For the time being, we had to disable Berkeley DB (BDB) in the Max binaries. If you require BDB support, please stick with 3.23.52 or recompile.
- Due to a hardware failure, our Solaris 2.8 build host is currently down. We will add the missing binary as soon as we have revived the system.
- Our Mac OS X build host has now been updated to Mac OS 10.2 aka "Jaguar" Therefore, this binary will most likely not work on older Mac OS X versions due to library incompatibilities. We will try to resolve this issue for the next release.
