LWJGL 2.9.2 has been released today. It adds support for OpenGL 4.5 but it’s mostly a bug fix release. Details here.
This will most likely be the last LWJGL 2 release. Pull requests that are well-written and properly tested will still be accepted and nightly builds will stay alive for the time being. If anyone is interested in taking over maintenance of the project, send me a PM (here or in the LWJGL forum).
Many thanks to everyone that has contributed to the project over the years!
