The range optimizer is coded, but only 85% tested. It can be enabled with --new, but it crashes core a lot yet...
More portable. Should compile on AIX and alpha-digital. At least the isam library should be relatively 64-bit clean.
New isamchk which can detect and fix more problems.
New options for isamlog.
Using new version of Automake.
Many small portability changes (from the AIX and alpha-digital port) Better checking of pthread(s) library.
czech error messages by <snajdr@pvt.net>.
Decreased size of some buffers to get fewer problems on systems with little memory. Also added more checks to handle ``out of memory'' problems.
mysqladmin: you can now do mysqladmin kill 5,6,7,8 to kill multiple threads.
When the maximum connection limit is reached, one extra connection by a user with the process_acl privilege is granted.
Added -O backlog=# option to mysqld.
Increased maximum packet size from 512K to 1024K for client.
Almost all of the function code is now tested in the internal test suite.
ALTER TABLE now returns warnings from field conversions.
Port changed to 3306 (got it reserved from ISI).
Added a fix for Visual FoxBase so that any schema name from a table specification is automatically removed.
New function ASCII().
Removed function BETWEEN(a,b,c). Use the standard SQL syntax instead: expr BETWEEN expr AND expr.
MySQL no longer has to use an extra temporary table when sorting on functions or SUM() functions.
Fixed bug that you couldn't use tbl_name.field_name in UPDATE.
Fixed SELECT DISTINCT when using 'hidden group'. For example:
mysql> SELECT DISTINCT MOD(some_field,10) FROM test -> GROUP BY some_field;
Note: some_field is normally in the SELECT part. Standard SQL should require it.
