Percona is glad to announce the release of Percona Server 5.5.27-29.0 on October 11th, 2012 (Downloads are available here and from the Percona Software Repositories).
Based on MySQL 5.5.27, including all the bug fixes in it, Percona Server 5.5.27-29.0 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 5.5.27-29.0 milestone at Launchpad.
Percona Server now supports XtraDB changed page tracking. This feature will be used for implementing faster incremental backups that use this information to avoid full data scans.
Number of binlog files can be restricted when using Percona Server with the new max_binlog_files option.
Fixed server assertion error related to buffer pool, only visible in debug builds. Bug fixed #905334 (Stewart Smith).

The binlog shouldn’t be rotated while it contains XA transactions in the PREPARED state. Bug fixed #1036040 (Stewart Smith).
Flashcache support resulted in confusing messages in the error log on Percona Server startup even when flashcache was not used. This was fixed by adding new boolean option –flashcache. When set to 0 (default), flashcache checks are disabled and when set to 1 checks are enabled. Error message has been made more verbose, it now includes the error number and system error message as well. Bug fixed #747032 (Sergei Glushchenko).
Custom server builds would crash when compiled with a non-default maximum number of indexes per table. Upstream MySQL bugs: #54127, #61178, #61179 and #61180. Bug fixed #1042517 (Sergei Glushchenko).
