CONGRATULATIONS, AND REJOICE, ADVENTURER LIBGDX! YOU HAVE GAINED 1 LEVEL. ROLL FOR HEALTH POINTS.
Yes, libGDX 1.12.0 is finally out! And about a day after that released, here's gdx-liftoff's release to coincide with it! I had to scramble to fix various mostly-small breaking changes that affected gdx-liftoff itself, and now you can experience the same rush of seething fury delighted excitement that I did! Expect many libraries to be potentially broken in the short-term, especially those that use scene2d.ui . As these libraries receive updates, many will be no-longer-broken soon. But, this libGDX version isn't all breaking changes! There's also plenty of new features and fixes, as shown by how many people were using and testing the 1.11.1-SNAPSHOT version before the release. One bug snuck through to the 1.12.0 release, but is already fixed by the custom GWT 2.10.0 backend I also maintain; if you use gdx-liftoff, you won't ever notice it. (It affected Tiled maps on GWT.)
This release is just a JAR; it includes the functionality that previously needed .bat files inside the JAR now. It should work without needing -XstartOnFirstThread on Mac. It should also work for Windows users with chars in their usernames that aren't only A-Z, a-z or 0-9. These are issues that Liftoff addresses in LWJGL3 for itself, and also for new LWJGL3 projects by adding a StartupHelper class and using it in the LWJGL3 launcher.
FARE THEE WELL, TRAVELER LIBGDX. MAY FORTUNE SMILE UPON YOUR NEWBORN PROJECTS.
