This release includes an update to Kotlin 1.8.0 for generated projects, and some long-standing minor issues have been fixed. Notably, when releasing on Android, minimization with ProGuard is enabled by default, so you will need to either configure ProGuard for your Android code or disable minimization in android/build.gradle . If you have any questions about this process, ask @Frosty-J , since he's been pushing for this change for a while. Various "tommyettinger libraries" have had their versions updated in yet another cascade of updates, this time affecting TextraTypist (now on 0.7.6) because one of its dependencies was broken (RegExodus, which should now be at least 0.1.15). In general, this is a very minor release and does nothing you couldn't manually do to an existing project, but it should make brand-new projects a little nicer to work with.
Like the last release, this is distributed as a .zip file; download and extract it first, then run either the .jar directly, or (if that doesn't work and you're on Windows), try running gdx-liftoff-non-a-z-name-1.11.0.7.bat, which has special fixes for the case where a user's username contains a non-A-Z letter or some punctuation. That case seems to break LWJGL3 apps (like Liftoff) unless they account for it carefully. If you're releasing an app or game that uses LWJGL3 as a .jar release, I'd at least consider copying and adapting that .bat file to run your .jar file instead of gdx-liftoff-1.11.0.7.jar ; you should be able to release to more users that way.
