Before reporting an issue search the tracker to make sure that it hasn't been reported yet.
Do not add notes that don't supply any new information. In particular, refrain from posting notes like "Please fix", "When is this going to be done?" or "I want this too". If you want to draw attention to a certain ticket, use the support ranking feature instead of posting pointless notes.
Notes that don't contain useful information will be deleted to keep the tickets clean of bloat. This is a bug tracker, not a forum.
When reporting a bug state whether the bug happens only offline, only online or both.
If a bug occurs offline, please test if it also happens in GZDoom.
Please test whether a bug occurs in the latest stable version and in the latest beta build.
Back Ports and Code Submissions
As a general rule, back port requests for new features will be ignored. Excepting for minor features, we usually only back port bug fixes.
Before requesting a feature back port, keep in mind that these back ports slow down major upgrades rather than speeding things up. In other words, if you want to see Zandronum support everything in the latest ZDoom, be patient.
Code submissions/pull requests are accepted, but avoid submitting back ports. The code review process usually takes as long as just doing the back port so it doesn't save us any work.
