FLUSH LOGS now rotates relay logs,
and a new variable max_relay_log_size.
Plus a very small bit of code cleaning.

Added MAX_PASSWORD_LENGTH. This increased master-slave passwords to 32 bytes (Bug #766)

Free memory used by replicate_xxx and binglog_xxx options

Fixed problem with localtime -> gmt where some times resulted in
different (but correct) timestamps. Now MySQL should use the smallest
possible timestamp value in this case.  (Bug 316)

  Search first only 10 % of the LRU list for a replaceable block before doing an LRU flush; enable again flushing of close pages also in a flush list (checkpointing) flush
trx0trx.c:
  Add forgotten return value (it was not used anywhere, fortunately)
ha_innodb.h, mysql_priv.h:
  Move declaration of srv_buf_pool_max_modified_pct to ha_innodb.h and enclose it to denote it is a C variable, not C++

Fixed wrong logging of Access denied error (Bug #398)

Fixed handling of lower_case_table_names in SHOW TABLE STATUS, mysql_list_fields() and mysql_table_dump().
This fixes some Errcode 13 errors on Windows when deleting tables.

(On Windows --log-error is enabled by default)

Call pthread_mutex_destroy() on not used mutex.
Changed comments in .h and .c files from // -> /* */
Added detection of mutex on which one didn't call pthread_mutex_destroy()
Fixed bug in create_tmp_field() which causes a memory overrun in queries that uses "ORDER BY constant_expression"
Added optimisation for ORDER BY NULL

Free row buffer cache after each query for MyISAM tables.
Added table join option FORCE INDEX
Fixed core dump bug when connecting with hostname that could not be resolved.

Fixed test suite for HPUX 10.20 and MacOSX

Made keybuff_size longlong (To make show variables work similar on 32
and 64 bit systems)
Fixed some 'not initalized variable errors' in multi-table-update.
Fixed memory leak in multi-table-update.
Now all tests works under valgrind without any errors.

Fixed 'not initialized' memory error.

New (simpler) internal timestamp handling.
More debuging to heap tables.
Small cleanups to multi-table-delete
false -> 0 and true -> 1  (We should use TRUE and FALSE)

Fix for shutdown on Mac OS X

Add support for LIMIT # OFFSET #
Changed lock handling:  Now all locks should be stored in TABLE_LIST instead of passed to functions.
Don't call query_cache_invalidate() twice in some cases
mysql_change_user() now clears states to be equal to close + connect.
Fixed a bug with multi-table-update and multi-table-delete when used with LOCK TABLES
Fixed a bug with replicate-do and UPDATE

Fixed bug in SELECT ... ORDER BY ... LIMIT

Changed usage of LOCK_thread_count -> LOCK_status for statistics variables

More DBUG info for replication
Better error messages from replication
Fixed bug in replication code when connecting to 'localhost' (time was not released properly)
Block ALARM signal on Linux for signal handler thread (Fixes problem with running mysqld with --debug)
Removed warning when setting an AUTO_INCREMENT field to NULL

able delay_key_write as default (as it was in 4.0.2)

Fixed some windows portability problems and removed some compiler warnings
 Cleaned up QUOTE() function and fixed bug in \0 and \Z handling.

Make safe_mysqld a symlink to mysqld_safe in binary distribution
Fixed problem with CTRL-C when using mysqld --bootstrap

Lots of code fixes to the replication code (especially the binary logging and index log file handling)
Fixed bugs in my last changeset that made MySQL hard to compile.
Added mutex around some data that could cause table cache corruptions when using OPTIMIZE TABLE / REPAIR TABLE or automatic repair of MyISAM tables.
Added mutex around some data in the slave start/stop code that could cause THD linked list corruptions
Extended my_chsize() to allow one to specify a filler character.
Extend vio_blocking to return the old state (This made some usage of this function much simpler)
Added testing for some functions that they caller have got the required mutexes before calling the function.
Use setrlimit() to ensure that we can write core file if one specifies --core-file.
Added --slave-compressed-protocol
Made 2 the minimum length for ft_min_word_len
Added variables foreign_key_checks & unique_checks.
