- Thanks to Hartmut Holzgraefe for reporting a memory leak when using the InnoDB memcached API and replication. Bug #70757.
- Thanks to Justin Swanhart for reporting that InnoDB reported an incorrect operating system error code when it failed to initialize. Bug #70867.
- Thanks to Yoshinori Matsunobu who reported that MySQL 5.6's persistent InnoDB statistics caused stalls due to latch contention. Bug #70768.
