http://lwjgl.org/forum/index.php?topic=2703Most remarkable are the support for Solaris (x86 only) and the option to attach the Display to an AWT Canvas without using the AWTGLCanvas. However, i haven't tried these new features yet. The current release of jPCT
won't work with this release of LWJGL, because some stuff that jPCT is using has moved from lwjgl.jar to lwjgl_util.jar.
The next release of jPCT will solely use the LWJGL 2.0 branch and drop support for the 1.x branch. If you want to play around with jPCT and LWJGL 2.0rc2 now, please let me know. I might release a beta that supports 2.0rc2 if there is some demand.
