GDevelop, the open source beginner friendly 2D game engine, just released beta 70. We recently mentioned GDevelop in our Codeless Game Engines article and have previously covered it in depth in this video.
There are no formal release notes, just this tweet:
The star feature of this release is certainly the ability to create custom behaviors using the build in event system, in addition to the existing JavaScript method. Details on creating custom behaviors is available here. GDevelop is available for Mac, Windows and Linux and can be downloaded here.
