This release only includes two, count 'em, two features! But one is quite important for any users on Linux, so if you're running everybody's favorite penguin-mascot OS, this release is for you! Linux was using Vis-UI as a fallback file picker because there had been numerous problems with both Tiny File Dialogs and Native File Dialogs on that OS. But, until I forked Vis-UI yesterday to update it, it wasn't working correctly with libGDX 1.14.1, and would crash at runtime if the fallback file picker was actually used. I've submitted a PR to Vis-UI, but merging it isn't needed for gdx-liftoff to be able to use the changes, thanks to the mighty JitPack!
The only other change is marking the Bullet extension for 3D physics as not ready on TeaVM, because it isn't working at this point.
As usual, there is the cross-platform JAR, three platform-specific JARs in case the cross-platform one isn't working, and two platform-specific native executables for users who don't have an easily-available JDK. You only need one of these! The cross-platform JAR, gdx-liftoff-1.14.1.1.jar, is probably the best option for most users.
Enjoy!
