Aleph One (formerly known as the Marathon Open Source Project) is a free and open-source first-person shooter engine based on the source code of Bungie Studios' Marathon 2: Durandal. The project commenced in early 2000, when Bungie released the code shortly before being acquired by Microsoft and spurred the fan community to further develop it. Since that time, Aleph One has become a successful project in terms of development and community support. Most modern-day and die-hard Marathon enthusiasts use Aleph One due to its enhancements over the original games and the fact that it is playable with today's platforms. Its name is taken from the second infinite cardinal number in transfinite arithmetic and references Marathon Infinity, the final game in the Marathon Trilogy.

Aleph One 0.23 is now available Highlights for this release include a completely new renderer option for Aleph One, written by Clemens Unterkofler and Jeremiah Morris. It supports a modern 3D perspective, parallax bump maps, and bloom. Consequently, you must have some minimal hardware to run it: a Radeon 9500 or GeForce FX5200 or better. To get good frame rates with all features turned on, you will need a modern GPU.

The one big thing about this release is that OS X 10.4 is now a requirement, not the predicted 10.3.9, it's 10.4 or stick to 0.22.
Some net games will be compatible between 0.23 and 0.22, rugby is not though and maps with the new lua functions obviously won't work.

Here's some images of the shaders in-game (Note the corrected perspective)

I dont really notice a big difference with the new shaders enabled, i haven't played in a while though. Also, does the "3D models" option in the graphics settings even do anything?

@pvt. Johnson
The 3D models option does something only if you make it so it does. In other words, the 3D models option doesn't do anything if you haven't put and set up a 3d model in aleph one, and barely any 3d models have been made for it, and they are barely any good. Another reason why 3d models are scarce in Aleph One is because it cuts down on the RAM, especially if there was a 3d model for every object, monster, scenery, and projectile.
