Game Maker 4.0

Game Maker Version 4.0 was released in July 2001, after Mark Overmars, creator of Game Maker, has decided that he had to redo Game Maker. He rewrote it completely from scratch, using all what he has learned over the years. The interface was completely changed. The new version was also not compatible with the old version. The new red color of the icon (instead of the blue) symbolised that.

Changes
There is no list of changes avialable between Game Maker 4.0 and Game Maker 3.3, since 4.0 is a complete rewrite, with hundreds of changes that are difficult to count.
