So basically on Thursday a new version of Boll has been released, that being 2.1.1, and from what I know there's another patch that's coming up, but it's now the default version, and it's highly recommended to use 2.1.1 for any upcoming speedruns as it widely changes both the base levels and character gameplay. If you don't know you can get the most recent version at the Boll Deluxe itch.io page. You can also check out Boll's Discord Server for more info on any patches or updates that may pop up.
