Percona is glad to announce the release of Percona Server 5.5.36-34.0 on March 10th, 2014 (Downloads are available here and from the Percona Software Repositories). Based on MySQL 5.5.36, including all the bug fixes in it, Percona Server 5.5.36-34.0 is now the current stable release in the 5.5 series. All of Percona‘s software is open-source and free, all the details of the release can be found in the 5.5.36-34.0 milestone at Launchpad.

New Features:

Debian and Ubuntu packaging has been reworked to meet the packaging standards.

Ability to change database for mysqlbinlog has been ported from Percona Server 5.1

Percona Server has implemented Slow Query Log Rotation and Expiration feature to provide users with better control of slow query log disk space usage.

In order to comply with Linux distribution packaging standards Percona’s version of libmysqlclient has been renamed to libperconaserver. The old name was conflicting with the upstream libmysqlclient. Except for packaging, libmysqlclient and libperconaserverclient of the same version do not have any differences. Users wishing to continue using libmysqlclient will have to install the corresponding package of their distribution, such as mysql-lib for CentOS and libmysqlclient18 for Ubuntu/Debian. Users wishing to build software against libperconaserverclient should install libperconaserverclient-dev package. An old version of Percona-built libmysqlclient will be available for download.

Bugs Fixed:

The XtraDB version number in univ.i was incorrect. Bug fixed #1277383.

Percona Toolkit UDFs were only shipped with RPM packages. Bug fixed #1159625.

Server could crash if it was signaled with SIGHUP early in the server startup. Bug fixed #1249193 (upstream #62311).

Server could crash if XtraDB innodb_dict_size_limit option was set due to incorrect attempts to remove indexes in use from the dictionary cache. Bugs fixed #1250018 and #758788.

Fix for bug #1227581, a buffer pool mutex split regression, was not complete, thus a combination of write workload and tablespace drop could crash the server if InnoDB compression was used. Bug fixed #1269352.

Binary RPM packages couldn’t be built from source tarballs on Fedora 19. Bug fixed #1229598.

Percona Server that was compiled from source package had different server version string from that of binary packages. Bug fixed #1244178.

InnoDB did not handle the cases of asynchronous and synchronous I/O requests completing partially or being interrupted. Bugs fixed #1262500 (upstream #54430), and #1263087 (Andrew Gaul).
