I was actually just wondering, what are the changes in the regularly released alpha versions of MFR?

Is it big changes or fixes? Should I update to them or is it very unstable to do so?

I just can't seem to find a change log or any information anywhere (sorry for my clumsiness) :( so I thought I'd simply ask here.

Oh okay thanks for the info, so since they sometimes add world corruption I'm guessing it's better to stay with the stable version for now? :)

Changes on the alpha builds are whatever was commited in the hour prior to their release - they're built and uploaded automatically.

Sometimes this is a fix for a crash, sometimes it changes code in a way that adds new crashes. There have even been a few that corrupted worlds. Occasionally, there have been no changes to the code whatsoever, and the alpha is exactly identical to the previous released build.
