XAMPP was on the cutting edge with MySQL 4.1. That was a big jump that involved changing tables.
MySQL 5 was released today, and although I'm not pushing for its immediate inclusion, it would be nice to know when XAMPP might move to MySQL 5. It includes some GREAT improvements, to name a few: Views, Triggers, Stored Procedures, a BIT data type, two new storage engines, including the very fast "ARCHIVE" engine, and more.
Any thoughts?
