Based on MySQL 5.6.36, including all the bug fixes in it, Percona Server 5.6.34-79.1 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 5.6.36-82.1 milestone at Launchpad.
Please note that RHEL 5, CentOS 5 and Ubuntu versions 12.04 and older are not supported in future releases of Percona Server and no further packages are added for these distributions.
Percona Server can now be built with support of OpenSSL 1.1.
Percona Server is now available on Debian 9 (stretch). The support only covers the amd64 architecture.
TokuDB enables to kill a query that is awaiting an FT locktree lock.
Row counts in TokuDB could be lost intermittently after restarts. Bug fixed #2.
In TokuDB, two races in the fractal tree lock manager could significantly affect transactional throughput for some applications that used a small number of concurrent transactions. These races manifested as transactions unnecessarily waiting for an available lock. Bug fixed #3.
TokuDB could assert when opening a dictionary with no useful information to error log. Bug fixed #23.
TokuDB could assert for various reasons deserializing nodes with no useful error output. Bug fixed #24.
Percona Server could crash when running a query over a partitioned table that uses an index to read a range of rows if this range was not covered by any existing partition. Bug fixed #1657941 (upstream #76418).
With two client connections to a server (debug server build), the server could crash after one of the clients set the global option userstat and flushed the client statistics (FLUSH CLIENT_STATISTICS) and then both clients were closed. Bug fixed #1661488.
TokuDB did not pass cmake flags on to snappy cmake. Bug fixed #41. The progress status for partitioned TokuDB table ALTERs was misleading. Bug fixed #42.
When a client application connecting to the Aurora cluster end point using SSL (–ssl-verify-server-cert or --ssl-mode=VERIFY_IDENTITY option), wildcard and SAN enabled SSL certificates were ignored. See also Compatibility Matrix. Note that the --ssl-verify-server-cert option is deprecated in Percona Server 5.7. Bug fixed #1673656 (upstream #68052).
Killing a stored procedure execution could result in an assert failure on a debug server build. Bug fixed #1689736 (upstream #86260).
It was not possible to build Percona Server on Debian 9 (stretch) due to issues with OpenSSL 1.1. Bug fixed #1702903 (upstream #83814).
The SET STATEMENT … FOR statement changed the global instead of the session value of a variable if the statement occurred immediately after the SET GLOBAL or SHOW GLOBAL STATUS command. Bug fixed #1385352.
[*]The synchronization between the LRU manager and page cleaner threads was not done at shutdown. Bug fixed #1689552.
Other bugs fixed: #6, #44, #65, #1160986, #1676740, #1689989, #1689998, #1690012, #1699788, and #1684601 (upstream #86016).
