For those who haven't heard yet, ZDoom's scripting branch was merged into the main development trunk following the release of 2.8.1. The gist of it is that major parts of ZDoom were rewritten in order to pave the way for the fabled DoomScript.
What this means is that there's a metric butt-ton of new/rewritten code in development builds of ZDoom, and while the devs have done their best to make the transition as smooth as possible, there are far too many mods out there for the dev crew to test on their own. It's inevitable that there are going to be things that just don't work quite right in newer versions... yet.
The short version: ZDoom needs your help! Here's what you can do to chip in:
- Grab a recent development build of ZDoom
- Fire up your (favorite) mod(s)
- Post bug reports in the Bugs Forum for anything that seems like it's borked in the newer versions that was working just fine in 2.8.1
- That's it. Simple, eh?
It'll be tough for a little while since none of us are used to having this many changes land in a dev build at once, but we'll get through it so long as those bug reports keep rolling in.
Now go forth and report!
