This release is in the 1.13.0.x line, but it itself uses libGDX 1.12.1, and projects generated with it can use 1.13.0 or 1.12.1 (which is currently the default), as well as the typical range of other versions. Why? WHYYYY??? Antivirus false positives started appearing for LWJGL 3.3.4 a little while ago, and libGDX 1.13.0 uses LWJGL 3.3.4, so Liftoff started getting flagged as a result. This also would have made projects using libGDX 1.13.0 become flagged by antivirus programs, which nobody wants! However, libGDX 1.12.1 is not affected, since it (usually) uses LWJGL 3.3.3 . Some earlier versions of Liftoff were also affected by this because they used the newer (nicer) file dialog library in LWJGL 3.3.4, and that forced a dependency on all of 3.3.4 . Ugh. So now we have to use the file dialog library NFD at version 3.3.1, because 3.3.2 and 3.3.3 were both broken in different ways. But, the jar release now gets through at least VirusTotal just fine: https://www.virustotal.com/gui/file/073834634c0400b0f897720925c2732e13bd8ee83300bc6a64be74143ace6deb?nocache=1
The native executables get through VirusTotal almost fine; Fortinet has a false positive that it doesn't name and nothing else finds anything suspicious. Fortinet finds a lot of false positives, it looks like.
Feature-wise, this release is very similar to 1.13.0.0 . Many third-party extensions have been updated, and Construo is 1.4.3 here now. Of course, the main feature is "this can be downloaded now, without antivirus software complaining."
I guess we gotta go back in time!
