An updated version 2.5.0.5 of the PrBoom+ port of the DOOM source code is now available as well as a newer version 2.5.0.6.test. If you are not familiar, here is what it is: "Doom-plus is a patched version of the original DOS exe for Doom2 (version 1.9) with increased limits to reduce the risk of crashes, premature program exits and certain visual problems. This is done without loss of compatibility - in other respects, Doom-plus behaves exactly like the original DOS exe. Dehacked patches can be applied as normal, for instance, and any demo that plays back correctly with Doom2.exe will also play back with Doom-plus." This Change Log has word on what's new.
