ZDoom Community Build
From ZDoom Wiki
ZDoom Community Build (also known as .96x) is ZDoom 2.0.96 source mod which added a lot of new features (mostly in DECORATE). ZDoom 2.1.x incorporates nearly all of its features (the one exception not being able to use Pickup and Use states with any inventory item) so using the unofficial build is no longer recommended. If you continue to do so be aware that you will get no support at all (bug reports will be discarded on sight.)
