This releasecontains all the bug fixes from latest Percona Server 5.5 release (currentlyPercona Server 5.5.31-30.3). New Features（新特性）:
Percona Server has implemented Log Archiving for XtraDB. Currently this feature implementation is considered ALPHA quality.
Transaction objects are now allocated calling calloc() directly instead of using InnoDB heap allocation. This may improve write performance for high levels of concurrency. Bug fixed #1185686.
Under very rare circumstances, deleting a zero-size bitmap file at the right moment would make server stop with an I/O error if changed page tracking is enabled. Bug fixed #1184517.
Missing path separator between the directory and file name components in a bitmap file name could stop the server starting if the innodb_data_home_dir variable didn’t have the path separator at the end. Bug fixed #1181887.
Changed page tracking used to hold the log system mutex for the log reads needlessly, potentially limiting performance on write-intensive workloads. Bug fixed #1171699.
Server would crash if an INNODB_CHANGED_PAGES query is issued that has an empty LSN range and thus does not need to read any bitmap files. Bug fixed #1184427.
Query to the INNODB_CHANGED_PAGES table would cause server to stop with an I/O error if a bitmap file in the middle of requested LSN range was missing. Bug fixed #1179974.
A warning is now returned if a bitmap file I/O error occurs after an INNODB_CHANGED_PAGES query started returning data to indicate an incomplete result set. Bug fixed #1185040.
Fixed the upstream bug #68970 that, in Percona Server, would cause small tablespaces to expand too fast around 500KB tablespace size. Bug fixed #1169494.
Fixed the RPM package dependencies issues. Bug fixed #1186831.
Reduced the overhead from the Handle Corrupted Tables check as it was missing branch predictor annotations. Bug fixed #1176864.
