## Bugs Fixed


* Setting the `none` value for slow_query_log_use_global_control
generates an error. Bugs fixed [#5813](https://jira.percona.com/browse/PS-5813).


* If [pam_krb5](https://docs.oracle.com/cd/E88353_01/html/E37853/pam-krb5-7.html) allows the
user to change their password, and the password expired, a new password may
cause a server exit. Bug fixed [#6023](https://jira.percona.com/browse/PS-6023).


* An incorrect assertion was triggered if any temporary tables should be logged
to binlog. This event may cause a server exit. Bug fixed [#5181](https://jira.percona.com/browse/PS-5181).


* The Handler failed to trigger on Error 1049, SQLSTATE 42000, or plain
sqlexception. Bug fixed [#6094](https://jira.percona.com/browse/PS-6094). (Upstream [#97682](http://bugs.mysql.com/bug.php?id=97682))


* When executing `SHOW GLOBAL STATUS`, the variables may return incorrect
values. Bug fixed [#5966](https://jira.percona.com/browse/PS-5966).


* The memory storage engine detected an incorrect `full` condition even
though the space contained reusable memory chunks released by deleted
records and the space could be reused. Bug fixed [#1469](https://jira.percona.com/browse/PS-1469).
