Which version of freedoom do these enemies come from?

I was planning to rework some freedoom sprites, but then I stumbled upon this thread and realized that most of what I planned (making chaingunners gun look like minigun that you are using, lost soul looking more alien-themed etc.) was already in some build:

Does anyone know which version is that? Are these sprites still around somewhere? Why were they even replaced/removed?

These sprites are accurate to the autobuild at that date: so commit 2f78eb3e17bcbad19a0924dec138d0754f20cbb1.

Also GOOD LORD, my eyes were violated by the filter on the sprites in that post.

My eyes are more violated by changes that were made to these enemies. Why turn chaingunner into player recolour? Why deepfry mancubus? Why remove details from zombies weapon and give it ridiculous legs? I thought these were like this from the start. Was it some copyright issues?

Edit: Nevermind, I went through old build from here https://archive.org/details/free-doom-2003-2019 and it turns out these were just reverted back to their beta versions. So they were in fact like this from start - I'm still curious what sort of copyright issues have newer sprites caused.

Edit2: I now realized that all updated sprites are back to new version in daily builds (I downloaded both Freedoom WADs from official Freedoom site). Man that new revenant is cool.

That was quite a ride all to realize that for the past month the only version that I knew and played was with placeholder beta enemies and that my boot-replacing operation was useless.

The latest version is always at: http://freedoom.soulsphere.org/

Updated semi-daily.
