MySQL 3.23.51 has been released.

MySQL 3.23.51 is now released. This version fixes several bugs and compile issues - see the changelog below for details. Most notably, we have switched back to using gcc 2.95.3 as the compiler for the Linux binaries and we now link against an updated version of the patched glibc.

The packages are available from http://www.mysql.com/downloads/ (http://www.mysql.com/downloads/) and mirror sites.

Changes in release 3.23.51

* Cleaned up NULL handling for default values in DESCRIBE table_name.
* Fixed truncate() to round up negative values to the nearest integer.
* Remove end space from enum values. (This fixed a problem with SHOW CREATE TABLE).
* Fixed bug in CONCAT_WS() that cut the result.
* Changed name of variables Com_show_master_stat to Com_show_master_status and Com_show_slave_stat to Com_show_slave_status.
* Changed handling of gethostbyname() to make the client library threadsafe even if gethostbyname_r doesn't exists.
* Fixed core-dump problem when giving a wrong password string to GRANT.
* Fixed bug in DROP DATABASE with symlinked directory.
* Fixed optimization problem with DATETIME and value outside DATETIME range.
* Removed BDB documentation.
* Fixed mit-pthreads to compile with glibc 2.2 (needed for make dist).

* Fixed the result from IF() is case in-sensitive if the 2 and third arguments are case sensitive.
* Fixed core dump problem on OSF in gethostbyname_r.
* Fixed that underflowed decimal fields is not zero filled.
* If we get an overflow when inserting '+11111' for decimal(5,0) unsigned columns, we will just drop the sign.
* Fixed optimization bug with ISNULL(expression_which_cannot_be_null) and ISNULL(constant_expression).
* Fixed host lookup bug in the glibc library that we used with the 3.23.50 Linux-x86 binaries.
