Changes in release 3.23.40
Fixed problem with --low-priority-updates and INSERT's.
Fixed bug in slave thread when under some rare circumstances it could get 22 bytes ahead on the offset in the master
Added slave_wait_timeout for replication.
Fixed problem with UPDATE and BDB tables.
Fixed hard bug in BDB tables when using key parts.
Fixed problem when using the GRANT FILE ON database.* ...; Previously we added the DROP privilege for the database.
Fixed that DELETE FROM table_name ... LIMIT 0 and UPDATE FROM table_name ... LIMIT 0 doesn't delete/update anything.
CHECK TABLE now checks if an auto_increment column contains the value 0.
Sending a SIGHUP to mysqld will now only flush the logs, not reset the replication.
Fixed parser to allow floats of type 1.0e1 (no sign after e).
Option --force to myisamchk now also updates states.
Added option --warnings to mysqld. Now mysqld only prints the error Aborted connection if this option is used.
Fixed problem with SHOW CREATE TABLE when you didn't have a PRIMARY KEY.
Fixed properly the rename of innodb_unix_file_flush_method to innodb_flush_method.
Fixed bug when converting UNSIGNED BIGINT to DOUBLE. This caused a problem when doing comparisons with BIGINT's outside 
of the signed range. Fixed bug in BDB tables when querying empty tables.
Fixed a bug when using COUNT(DISTINCT) with LEFT JOIN and there wasn't any matching rows.
Removed all documentation referring to the GEMINI table type. GEMINI is not released under an Open Source license.
