Fixed compiler warnings (a lot of hidden variables detected by the Forte compiler)
Added a lot of 'version_xxx' strings to 'show variables'
Prevent copying of TMP_TABLE_PARAM (This caused core dump bug on Solaris)
Fixed problem with printing sub selects to debug log
Fix the OS error 2 reported by Miguel and Mark in Windows crash recovery: a * had been forgotten from the path in directory scanning
ha_innodb.cc:
Set default directory in fil0fil.c right if we are running the Embedded Server Library, where the default dir of the process is not necessarily the MySQL datadir
Merge with ibbackup; bug fix: .ibd files were extended 2 x the required amount; InnoDB does not create the small file inno_arch_log... any more at database creation
Check that writes to data files always happen in to addresses divisible by 16 kB, and the chunk size is also divisible by 16 kB; a user reported 2 corrupt pages from Linux-2.4.20 where an index page seemed displaced

Multiple tablespaces for InnoDB
sql_table.cc:
Tell explicitly that InnoDB should retrieve all columns in CHECKSUM TABLE
sql_update.cc, sql_select.cc, my_base.h:
More descriptive flag name HA_EXTRA_RETRIEVE_ALL_COLS
Merge
trx0trx.c:
Print more info about a trx in SHOW INNODB status; try to find the bug reported by Plaxo
buf0buf.c:
Check that page log sequence numbers are not in the future
log0recv.c, log0log.c:
Fixed a bug: if you used big BLOBs, and your log files were relatively small, InnoDB could in a big BLOB operation temporarily write over the log produced AFTER the latest checkpoint. If InnoDB would crash at that moment, then the crash recovery would fail, because InnoDB would not be able to scan the log even up to the latest checkpoint. Starting from this version, InnoDB tries to ensure the latest checkpoint is young enough. If that is not possible, InnoDB prints a warning to the .err log
Merge InnoDB-4.0.14: SAVEPOINT now implemented; InnoDB now accepts also column prefix keys; crashing bug in ON UPDATE CASCADE fixed; page checksum formula fixed
Release all event semaphores at shutdown also in Windows
srv0start.c, srv0srv.c:
make test sometimes failed because lock timeout thread exited without decrementing the InnoDB thread counter
The problem yesterday in ERROR_LOCK_VIOLATION was not InnoDB Hot Backup, but some file system backup tool: add to file writes 100 retries with 1 second waits
Merge InnoDB-4.0.5: new isolation levels READ COMMITTED and READ UNCOMMITTED now supported, selective deadlock resolution
mysqld.cc:
Change MySQL default isolation level to REPEATABLE READ; note that InnoDB has always had that default, and BDB and MyISAM always run at SERIALIZABLE level anyway
Change srv_flush_log_at_trx_commit to ulint, note that ibool is defined as ulint, so this is purely formal change
os0file.c:
Start using unbuffered i/o again in Windows because sequential read using normal i/o was 4 times slower in XP
Put 'last millisecond' test to make sure page checksum errors do not result from memory corruption in InnoDB
os0thread.c, configure.in:
Make sure stack size in InnoDB threads in AIX is at least 32 kB
