Contrary to some beginner's rumours, Gamestudio upgrades are of course always 100% compatible to their predecessors. We guarantee that all previously properly working projects will still work as before. All possible incompatibilites are mentioned in the update sheet.
BUT: The behavior can be different when there already was something wrong in the script before.
I start to think you really belief this.
But if you take a look at the
bug list you have to realize that updating the engine must end in broken projects in some cases.
