Inc the version

  Added missing 'Q' for -Q option

  Better error message if we hit the max process size in FreeBSD

  Add better error message if access rights are wrong

  Fix typo

  Improve error messages which may occur in installation

  Remove erroneous warning of a duplicate key when the key in a UNIQUE secondary index contains a NULL

into donna.mysql.fi:/home/heikki/mysqlm

  Make InnoDB startup option samples easier to understand, recommend not setting log files too big, because recovery slow

  Eliminate a gcc compiler bug in inlining

  Make os_file_flush to ignore the error we get from a raw device in fsync

  Changed default of file_io_threads to 4 and lock_wait_timeout to 50 seconds
  Added a missing break: if not specified, innodb_fast_shutdown got the same value as ..flush_log_at_trx commit

  Print progress info of the applying log records to the database phase in recovery
srv0srv.c:
  Do buffer pool flush and checkpoints more often to make recovery faster

  Increase table comment print size to 500 bytes to be able to print more foreign key constraint infos
ha_innobase.h:
  Change max key len back to 500 bytes because MySQL interpreter cannot handle more

  Allow foreign keys refer between fixed and var length strings

  Lower max key len to 3500 bytes because a secondary index record must also contain the primary key value

  Make sure no memory overrun of key buffer in range estimation

  Allow equal key values in a unique secondary index if the key value contains an SQL NULL

  Add warnings to recovery in some cases where log file might be corrupt and consequently recovery can be trusted less than normally

instead of DO RELEASE_LOCK()

  Add better instructions on how to specify innodb_data_file_path etc.

  Cleanup

  Do less statistics calculations for tables
dict0mem.h, row0mysql.c:
  Make calculation of new statistics less frequent, because the statistics in 3.23.44 involves many random disk reads

  Do not automatically calculate new statistics when a temporary table is used by MySQL in a query. The fact that some ORDER BY queries were slow may have been explained by this unnecessary statistics calculation.
