A new libGDX release is probably coming soon, so what better time to release a (Final? Maybe?) release of gdx-liftoff that defaults to libGDX 1.13.1 ! There aren't a ton of changes here, but various updates are present that are meant to make users who are "just starting out" have an easier time.
The biggest change is that gdx-liftoff uses ANGLE with LWJGL3, and defaults to using it in new LWJGL3 projects as well. You can remove ANGLE easily enough from new projects (it only needs removing one dependency and one line in Lwjgl3Launcher), but I think it is usually good to keep it simply because it works on more machines without needing fiddling with drivers or compatibility settings. Some users have said games using ANGLE have less stuttering or frame drops on their machines. Because ANGLE uses built-in DirectX on Windows, it doesn't need updated GPU drivers as often. ANGLE also has compatibility improvements with Apple Silicon on Macs. It does make the JAR or compiled EXE larger, but not by much -- a few music files are often much larger than the entire added ANGLE dependency. It also only affects desktop projects using LWJGL3, so Android and iOS apps won't get bloated, and browser-based games won't be any heavier.
Construo has been updated to 2.0.1, which has some improvements... that... I can't remember exactly. I think there were some changes that mostly help releases being published to distribution services like Steam and Itch.io .
Kotlin, Groovy, and Scala defaults have been updated (you may need to deselect and reselect the checkboxes to get the new versions plugged in). Various third-party dependencies have been updated. SquidSquad should finally no longer select an old version of its library (which happened because of a comparison quirk). Internally, any usage of LML, Autumn, and Autumn MVC is gone, which cleans up the Kotlin code quite a bit and gives us less code to maintain.
As usual, use the JAR if you have a JDK ready to go, or one of the zipped executables if you don't know if your JDK will work. If you rely on a JDK installed by your IDE, and don't have another, you may want to install a free OpenJDK version such as BellSoft Liberica, Azul Zulu, or Microsoft's OpenJDK, since that will allow you to run JARs you make without needing your IDE. There are lots of options out there for OpenJDK distributions, though Oracle's are not recommended here due to confusing licensing practices and less-than-helpful installer defaults. Eclipse Adoptium (also called Temurin) is great on Linux and Mac, but has had past issues with its installer on Windows, so if you are using any MSI installer on Windows, there are the earlier-mentioned options that are good first picks. Amazon Corretto has been trouble in the past by not shipping a functionally-equivalent package to other OpenJDK vendors; it may have improved since those days. JetBrains Runtime, or JBR. is a type of JDK (not a JRE, despite the name) that offers better hot-swapping support, so it may be a good choice if you want to do that during debugging (I have no experience with its installer, if there is one, but at least some version of JBR comes with IntelliJ IDEA and maybe also Android Studio).
So, with a new libGDX release hopefully coming soon, this may just be a capstone on the 1.13.1 releases that were labeled as 1.13.5 releases. A new day approaches!
