Now if we have a project we don't want to bring forward to a newer version of Blender, have problems with Add-ons that worked in previous versions but not in the newest version, want to follow an old time tutorial without the hassle of looking for keypresses or menu changes in the newer versions or if we want to stick with a certain version of Blender, we can do all that here on Steam.

So at the time this guide was created, roll back version available are 2.77a, 2.78c, 2.79a and 2.79b, 2.80, 2.81a, 2.82a, 2.83LTS (also known as 2.83.0) or if you are just downloading Blender for the first time or decide to opt-out, the most current version on Steam will be installed (which is currently 2.83.1 at the time I created this guide.) The versions available are the last stable release of the particular Version you select and the breaks are where there may be a particular change to Blender that affects the look or feel of Blender. The Blender Release Team here on Steam has given us the ability to roll back versions of Blender to Version 2.77a
