New Features
Kill Idle Transactions feature has been re-implemented by setting a connection socket read timeout value instead of periodically scanning the internal InnoDB transaction list. This makes the feature applicable to any transactional storage engine, such as TokuDB, and, in future, MyRocks. This re-implementation is also addressing some existing bugs, including server crashes: #1166744, #1179136, #907719, and #1369373.
Bugs Fixed
Logical row counts for TokuDB tables could get inaccurate over time. Bug fixed #1651844 (#732).

Repeated execution of SET STATEMENT ... FOR <SELECT FROM view> could lead to a server crash. Bug fixed #1392375.

CREATE TEMPORARY TABLE would create a transaction in binary log on a read only server. Bug fixed #1539504 (upstream #83003).

If temporary tables from CREATE TABLE ... AS SELECT contained compressed attributes it could lead to server crash. Bug fixed #1633957.

Using Per-query variable statement with subquery temporary tables could cause a memory leak. Bug fixed #1635927.

Fixed new compilation warnings with GCC 6. Bugs fixed #1641612 and #1644183.

A server could crash if a bitmap write I/O error happens in the background log tracking thread while a FLUSH CHANGED_PAGE_BITMAPS is executing concurrently. Bug fixed #1651656.

TokuDB was using wrong function to calculate free space in data files. Bug fixed #1656022 (#1033).

CONCURRENT_CONNECTIONS column in the USER_STATISTICS table was showing incorrect values. Bug fixed #728082.

InnoDB index dives did not detect some of the concurrent tree changes, which could return bogus estimates. Bug fixed #1625151 (upstream #84366).

INFORMATION_SCHEMA.INNODB_CHANGED_PAGES queries would needlessly read potentially incomplete bitmap data past the needed LSN range. Bug fixed #1625466.

Percona Server cmake compiler would always attempt to build RocksDB even if -DWITHOUT_ROCKSDB=1 argument was specified. Bug fixed #1638455.

Adding COMPRESSED attributes to InnoDB special tables fields (like mysql.innodb_index_stats and mysql.innodb_table_stats) could lead to server crashes. Bug fixed #1640810.

Lack of free pages in the buffer pool is not diagnosed with innodb_empty_free_list_algorithm set to backoff (which is the default). Bug fixed #1657026.

mysqld_safe now limits the use of rm and chown to avoid privilege escalation. chown can now be used only for /var/log directory. Bug fixed #1660265. Thanks to Dawid Golunski (https://legalhackers.com).

Renaming a TokuDB table to a non-existent database with tokudb_dir_per_db enabled would lead to a server crash. Bug fixed #1030.

Read Free Replication optimization could not be used for TokuDB partition tables. Bug fixed #1012.
Other bugs fixed: #1486747 (upstream #76872), #1633988, #1638198 (upstream #82823), #1638897, #1646384, #1647530, #1647741, #1651121, #1156772, #1644569, #1644583, #1648389, #1648737, #1650247, #1650256, #1650324, #1650450, #1655587, and #1647723.
