Bug 修复： 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. Percona FT could assert when opening a dictionary with no useful information to an error log. Bug fixed #23. Percona FT could assert for various reasons deserializing nodes with no useful error output. Bug fixed #24. It was not possible to build Percona Server on Debian 9 (stretch) due to issues with OpenSSL 1.1. Bug fixed #1702903 (upstream #83814). Packaging was using the dpkg --verify command which is not available on wheezy/precise. Bug fixed #1694907. Enabling and disabling the slow query log rotation spuriously added the version suffix to the next slow query log file name. Bug fixed #1704056.

When a client application is 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. 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). 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.
