CHECK TABLE
now works for
InnoDB
tables.
A new my.cnf
parameter
innodb_unix_file_flush_method
introduced.
It can be used to tune disk write performance.
An auto-increment column now gets new values past the transaction mechanism. This saves CPU time and eliminates transaction deadlocks in new value assignment.
Several bugfixes, most notably the rollback bug in 3.23.38.
