- Now MyRocks Storage Engine has General Availability status.
- Binary log encryption has been implemented and can be now switched on using the
variable, introduced in the previous release, but undocumented, allows to log information about all lock wait timeout errors.
- Intermediary slave with Blackhole storage engine couldn’t record updates from master to its own binary log in case master has the
binlog_rows_query_log_eventsoption enabled. Bug fixed #1722789 (upstream #88057).
- Help command in the mysql command line client provided a link to an older version of the Percona Server manual. Bug fixed #1708073.
- A regression in the
mysqld_safescript forced it to print an extra error when stopping the MySQL service. Bug fixed #1738742.
- Blackhole storage engine was incompatible with a newer length limit of the InnoDB index key prefixes. Bug fixed #1733049 (upstream #53588).
- Heartbeats received by slave were reacted with
mysql.slave_master_infotable sync on each of them even with
sync_master_infoset to zero, causing a huge increase in write load. Bug fixed #1708033 (upstream #85158).
- The replication writebatch functionality has been removed from Percona Server 5.7 due to unsafety of the current implementation.
