Release notes 

Percona is glad to announce the release of Percona Server for MySQL 5.5.30 -30.1 on March 7, 2013 (Downloads are available here and from the Percona Software Repositories). Based on MySQL 5.5.30, including all the bug fixes in it, Percona Server 5.5.30-30.1 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 5.5.30-30.1 milestone at Launchpad.

Bugs Fixed:

    Minor optimization cleanup by removing unnecessary current_thd calls. Bug fixed #1121794 (Alexey Kopytov).
    Fixed the regression introduced with the fix for bug #1083058 which caused unnecessary mutex re-acquisitions in adaptive flushing. Bug fixed #1117067 (Laurynas Biveinis).
    Percona Server would do unnecessary slow log stats accounting even with the slow log disabled. Bug fixed #1123915 (Alexey Kopytov).
    Optimization cleanup to avoid calls related to extended slow query log stats when this feature is disabled. Bug fixed #1123921 (Alexey Kopytov).
    The static srv_pass_corrupt_table variable could share CPU cache lines with InnoDB row counters, which resulted in high false sharing effect in high-concurrent workloads. Bug fixed #1125259 (Alexey Kopytov).
    Fixed the regression introduced with fix for bug #791030 in Percona Server 5.5.13-20.4 by implementing an optimized version of the same function. Bug fixed #1130655 (Alexey Kopytov).
    Bug fixed #1132350 (Alexey Kopytov).
    Bug fixed #1132351 (Alexey Kopytov).
