Percona Server 5.6.21-70.1 发布，该版本主要是 bug 修复，包括：
A slave replicating in RBR mode would crash, if a table
definition between master and slave differs with an allowed conversion,
and the binary log contains a table map event followed by two row log
events. This bug is an upstream regression introduced by a fix for bug #72610. Bug fixed #1380010. An incorrect source code function attribute would cause MySQL to crash on an InnoDB row write, if compiled with a recent GCC with certain compilation options. Bug fixed #1390695 (upstream #74842). MTR tests for Response Time Distribution were not packaged in binary packages. Bug fixed #1387170. The RPM packages provided for CentOS 5 were built using a debugging information format which is not supported in the gdb version included with CentOS 5.10. Bug fixed #1388972. A
session on a server in mixed mode binlogging would switch to row-based
binlogging whenever a temporary table was created and then queried. This
switch would last until the session end or until all temporary tables
in the session were dropped. This was unnecessarily restrictive and has
been fixed so that only the statements involving temporary tables were
logged in the row-based format whereas the rest of the statements would
continue to use the statement-based logging. Bug fixed #1313901 (upstream #72475).
