I've been trying to get versions of WoW from before v0.5.3 for ages now, contacting various devs involved with WoW at that time, to no avail. There's a few videos of the ECTS 2001 reveal of WoW that show a much earlier form of the game, likely pre-alpha, possibly without any version numbering system in use. There's also v0.6, which I've had no luck in finding, which bridged the gap between the Dec. 2003 alpha leak and the early public betas. There's patch notes available, so I know such a version and client existed, but whether or not it's still on the internet remains to be seen.
I must say thanks to everyone that's collaborating these patches - in the past, I have explored the WotLK F&F files using 3.3.5, but it's certainly nice to see the files being shared in a user-friendly sort of way.
