Based on MySQL 5.6.24, including all the bug fixes in it, Percona Server 5.6.24-72.2 is the current GA release in the Percona Server 5.6 series. All of Percona‘s software is open-source and free, all the details of the release can be found in the 5.6.24-72.2 milestone at Launchpad.
A server binary as distributed in binary tarballs could fail to load on different systems due to an unsatisfied
libssl.so.6dynamic library dependency. This was fixed by replacing the single binary tarball with multiple tarballs depending on the OpenSSL library available in the distribution: 1) ssl100 - for all Debian/Ubuntu versions except Squeeze/Lucid (
libssl.so.1.0.0 => /usr/lib/x86_64-linux-gnu/libssl.so.1.0.0 (0x00007f2e389a5000)); 2) ssl098 - only for Debian Squeeze and Ubuntu Lucid (
libssl.so.0.9.8 => /usr/lib/libssl.so.0.9.8 (0x00007f9b30db6000)); 3) ssl101 - for CentOS 6 and CentOS 7 (
libssl.so.10 => /usr/lib64/libssl.so.10 (0x00007facbe8c4000)); 4) ssl098e - to be used only for CentOS 5 (
libssl.so.6 => /lib64/libssl.so.6 (0x00002aed5b64d000)). Bug fixed #1172916.
A string literal containing an invalid UTF-8 sequence could be treated as falsely equal to a UTF-8 column value with no invalid sequences. This could cause invalid query results. Bug fixed #1247218 by a fix ported from MariaDB (MDEV-7649).
.debbinaries were built without fast mutexes. Bug fixed #1433980.
audit_log_filewould point to random memory area if the Audit Log Plugin was not loaded into server, and then installed with
INSTALL PLUGIN, and
audit_log_filesetting. Bug fixed #1437505.
A specific trigger execution on the master server could cause a slave assertion error under row-based replication. The trigger would satisfy the following conditions: 1) it sets a savepoint; 2) it declares a condition handler which releases this savepoint; 3) the trigger execution passes through the condition handler. Bug fixed #1438990 (upstream #76727).
Percona Server client packages were built with with
Readline. This was causing history file produced by the client no longer easy to read. Further, a client built with
EditLinecould display incorrectly on PuTTY SSH client after its window resize. Bugs fixed #1266386, #1296192 and #1332822 (upstream #63130, upstream #72108 and #69991).
Unlocking a table while holding the backup binlog lock would cause an implicit erroneous backup lock release, and a subsequent server crash or hang at the later explicit backup lock release request. Bug fixed #1371827.
Initializing slave threads or executing
CHANGE MASTER TOstatement would crash a debug build if autocommit was disabled and at least one of slave info tables were configured as tables. Bug fixed #1393682.
