Percona Server 5.5.36-34.0

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.

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