Percona is glad to announce the release of Percona Server for MySQL 5.5.31-30.3 on May 24, 2013 (Downloads are available here and from the Percona Software Repositories). Based on MySQL 5.5.31, including all the bug fixes in it, Percona Server 5.5.31-30.3 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 5.5.31-30.3 milestone at Launchpad.

New Features:

Bugs Fixed:

  • Fix for bug #1131187 introduced a regression that could cause a memory leak if query cache was used together with InnoDB. Bug fixed #1170103.
  • Fixed the RPM packaging regression that was introduced with the fix for bug #710799. This regression caused mysql schema to be missing after the clean RPM installation. Bug fixed #1174426.
  • Fixed the Percona-Server-shared-55 and Percona-XtraDB-Cluster-shared RPM package dependences. Bug fixed #1050654.
  • Fixed the upstream bug #68999 which caused compiling Percona Server to fail on CentOS 5 and Debian squeeze due to older OpenSSL version. Bug fixed #1183610.
  • If a slave was running with its binary log enabled and then restarted with the binary log disabled, Crash-Resistant Replication could overwrite the relay log info log with an incorrect position. Bug fixed #1092593.
  • Fixed the CVE-2012-5615 vulnerability. This vulnerability would allow remote attacker to detect what user accounts exist on the server. This bug fix comes originally from MariaDB (see MDEV-3909). Bug fixed #1171941.
  • Fixed the CVE-2012-5627 vulnerability, where an unprivileged MySQL account owner could perform brute-force password guessing attack on other accounts efficiently. This bug fix comes originally from MariaDB (see MDEV-3915). Bug fixed #1172090.
  • mysql_set_permission was failing on Debian due to missing libdbd-mysql-perl package. Fixed by adding the package dependency. Bug fixed #1003776.
  • Rebuilding Debian source package would fail because dpatch and automake were missing from build-dep. Bug fixed #1023575 (Stephan Adig).
  • Backported the fix for the upstream bug #65077 from the MySQL 5.6 version, which removed MyISAM internal temporary table mutex contention. Bug fixed #1179978.
