Drama in open source land, as a major conflict has caused many developers to leave GZDoom behind to fork it into UZDoom. It seems like going forward most people will end up using UZDoom.

What actually happened? In the official Discord server that covers ZDoom and related projects, an announcement was put up by a moderator noting "Due to a conflict between GZDoom's lead developer/maintainer Graf Zahl, a lot of other developers decided to leave GZDoom and work on a new fork of the engine now known as UZDoom".

They continued to note that "UZDoom is a direct continuation of GZDoom and will inherit all of its features (and add more eventually)" but the point is that it will have "a more stable development structure with healthy collaboration and less power given to individual 'project leads'".

Looking a bit further into it, a bug report on the GZDoom GitHub page titled "Project management" was opened that gave a little more detail noting issues with the lead of GZDoom pushing untested code, using an LLM to write code and hiding "not insignificant changes in commits, which has people worried that you'll randomly rip out features that they rely on". In reply, the project lead simply said "Feel free to fork the project under a" (yes, that really all they said).

A later comment before the bug report was locked points out the specific change in GZDoom that was made with ChatGPT.

Really a shame when such incredible projects go through issues like this. Hopefully the ZDoom / UZDoom will come out healthier and stronger from this with a more community orientated approach to the code.

not involved into gzdoom in any way
Well, just maybe all the people who are involved and did the nuclear option of forking an established thing know a bit more than you do?

I get that you think it's a shame, but at least in FOSS communities, instead of a bunch of firings and a big nose deciding they're gonna 'stay the course' anyway, you get a new fork with new rules/guidelines and the public can decide for themselves what path they like more.

Seeing it in context of how capitalist enterprises normally handle these situations, it no longer feels like a shame to me, it feels like a triumph. FOSStastic!

This whole thing reminds me of the openoffice/libreoffice split all those years ago. I remember at the time going "whoa, this is a huge deal" and not being sure how it would all work out.

Now, a bunch of years later, libreoffice is THE defacto gold standard, it's used and liked (mostly lol) everywhere, and I haven't even heard of openoffice in an eternity. I did just now look it up, but it looks like abandonware. Apparently Apache runs it? But it hasn't been updated in two years.

I've seen some of the drama over the years (well decades), and that unfinished sentence seems like a fitting end to the latest events. I'm sure that the other developers' reactions can only look harsh from the outside.

I want to highlight Kinsie's comment on GitHub as I think it is very accurate:
The recent progress under the more collaborative, team-based practices of late has been magnificent. It'd be a pity to see that get undermined.
