hi,
the MySQL server on zedler will be upgraded to MySQL 5.0 some time today or tomorrow morning (within the next 12 hours). the downtime should be minimal; all database will be converted automatically.
MySQL 5.0 adds several new features such as SQL stored procedures and views to MySQL. a summary of changes can be found here:

this upgrade is now complete. the PHP CGI has also been rebuilt against the new MySQL libraries (which are in /opt/mysql50/). please report any problems.
rgds, kate.
