BUGS FIXED
Symlinks to libmysqlclient libraries were missing on CentOS 6. Bug fixed #1408500.
RHEL/CentOS 6.6 openssl package (1.0.1e-30.el6_6.9), containing a fix for CVE-2015-4000, changed the DH key sizes to a minimum of 768 bits. This caused an issue for MySQL as it uses 512 bit keys. Fixed by backporting an upstream 5.7 fix that increases the key size to 2048 bits. Bug fixed #1462856 (upstream #77275).
innochecksum would fail to check tablespaces in compressed format. The fix for this bug has been ported from Facebook MySQL 5.1 patch. Bug fixed #1100652 (upstream #66779).
Issuing SHOW BINLOG EVENTS with an invalid starting binlog position would cause a potentially misleading message in the server error log. Bug fixed #1409652 (upstream #75480).
While using max_slowlog_size, the slow query log was rotated every time slow_query_log was enabled, not really checking if the current slow log is indeed bigger than max_slowlog_size or not. Bug fixed #1416582.
If query_response_time_range_base was set as a command line option or in a configuration file, its value would not take effect until the first flush was made. Bug fixed #1453277 (Preston Bennes).
Prepared XA transactions with update undo logs were not properly recovered. Bug fixed #1468301.
Variable log_slow_sp_statements now supports skipping the logging of stored procedures into the slow log entirely with new OFF_NO_CALLS option. Bug fixed #1432846.
