What is the difference between 2.0 and any of the other versions?

2.2 Is the best version for every category besides unrestricted Any% (The one with WRs less than a minute long) as it's more stable and doesn't really have occasional frame skips, which 2.0 has been accused of having. Version 2.0 plays almost entirely identical to 2.2, though this version doesn't have text storage patched out. If you want to run Any% with version 2.0, there is a "glitchrunners beta" under betas that you can opt in on steam. For the other categories, you're better off using the latest version.
