This release includes some minor fixes and ports back some changes/optimizations that i did for the Android version like faster animations for compiled objects and much faster normal calculations. It also includes the latest version of LWJGL that works fine with ATI cards again.

Have fun!
Edit: I've just noticed that the ReflectionHelper in util lacks documentation...sorry for that, i'll add it later.
I've uploaded a new zip that includes the documentation for the ReflectionHelper as well as a fix for calcMinDistance methods in World.
As usual, thanks a lot for maintaining this awesome engine, Egon. By the way, has the mergeAllObjects optimization been included on the current downloadable file (which preceded this release)?
It's part of the beta jar, but not of the official 1.21 release. I also plan to upload a new beta jar today.
Edit: The beta jar has been updated with some small fixes and optimizations.
