This is a relatively simple fork of DCSS that brings back removed and experimental playable races.
currently has: Skeleton, High Elf, Sludge Elf, Imp, Lava Orc, Plutonian, and Dorf (similar to HD and MD)
This forum thread has discussion and images that summarize the new races:

The README explains further, and has dead-simple install instructions for Linux:

1.4 stuff:
- imp teleportitis is now blinkitis
- plutonians malmutate a ton less often. they SHOULD only mutate when they accidentally explode from extreme contamination, and there's a small chance to get a good mutation, too.
- lots of fiddly apt tweaks partially based on player feedback and dev testing. maybe need to chill on changing apts so much
- (dev testing? which dev? that's me, I'm "the dev"! that still sounds weird.)
- adopted SKELETONS! from https://github.com/PabloMansanet/crawl/commits/skeleton
- they don't have a home on any servers yet, so Yiufcrawl can take them in for now
- merged in a bunch of stuff from upstream, aka trunk, aka dcss, aka "normal crawl".
- look here for more details https://github.com/yrmvgh/crawl/commits/yiuf
- Spellbooks no longer cost any space in your inventory. You can simply carry all of them around for free! The "spell library" patch by Doesnty.
- A few god-related tweaks from Hellmonk, including simplifying Dithmenos and slowing down the gift-spam of Oka & Trog.
- Removed rings of flight, fire resist, and cold resist. Now rings of fire/ice provide one pip of resistance with no vulnerability. Thanks, Hellmonk!
