-
Changed documentation string of
--with-unix-socket-path to avoid
confusion.
-
Added ODBC and ANSI SQL style
LEFT OUTER JOIN.
-
The following are new reserved words:
LEFT, NATURAL,
USING.
-
The client library now uses the value of the environment variable
MYSQL_HOST as the default host if it's defined.
-
SELECT column, SUM(expr) now returns NULL for column when
there are matching rows.
-
Fixed problem with comparing binary strings and
BLOBs with ASCII
characters over 127.
-
Fixed lock problem: when freeing a read lock on a table with multiple
read locks, a thread waiting for a write lock would have been given the lock.
This shouldn't affect data integrity, but could possibly make
mysqld
restart if one thread was reading data that another thread modified.
-
LIMIT offset,count didn't work in INSERT ... SELECT.
-
Optimized key block caching. This will be quicker than the old algorithm when
using bigger key caches.
