This is the final dev snapshot for 4.2, signaling the end of the feature development cycle, and the start of the beta phase. We spent the past couple of weeks wrapping up many of the big feature PRs which had been in development for the past few weeks and months. We still have a handful that the production team is keeping tabs on, but we’ll soon declare the full feature freeze for 4.2 and get ready for the first beta snapshot. But don’t wait for the beta to try what’s new in 4.2 – there are tons of amazing new features in this dev snapshot which require testing and user feedback, so we can iron out the main issues before the stable release. Here’s a selection of some of the biggest changes since our previous 4.2 dev 5 build, ahead of a more complete list below: The rendering contributors have outdone themselves this cycle, and a lot of their work has been merged for this snapshot: AMD’s FSR 2.2 has been implemented as a new upscaling option in the project settings. Have fun testing it and let us know how it goes :) An optional ANGLE-backed OpenGL renderer was added for macOS and Windows (GH-72831). ANGLE is a compatibility layer for OpenGL on top of Metal and Direct3D 11, which allows us to work around the deprecated and unmaintained OpenGL drivers on macOS, and similarly outdated OpenGL drivers on Windows for some older integrated chipsets. This should increase the portability of Godot games on lower end devices. Talking about the OpenGL Compatibility renderer, one of its main missing features, 3D shadows, has now been implemented (GH-77496)! For lightmapping, we replaced the extremely bulky and slow OIDN denoiser with a lightweight and much faster JNLM denoiser compute shader (GH-81659). Differences in denoising quality are likely to show up with the JNLM approach, sometimes for better or worse. While it lacks an AI component, it can leverage the albedo and normal information to fix errors that were impossible to address with OIDN. Please try it out and let us know if you’re happy with the results. If there’s demand for it, we might re-introduce OIDN as an option, using it as a standalone command line tool instead of building it together with Godot. With the built-in OIDN removed, editor binaries are now approximately 4-5 MB smaller. A lot more bug fixes to lightmapping quality and consistency, such as GH-61910, GH-81545, GH-81872, GH-81951, and GH-82533. We also forward-ported the OpenXR foveated rendering support from Godot 3.x (GH-80881). Glow behavior has been optimized to be closer to the high quality mode we had in Godot 3.x (GH-82353). On the animation front, AnimationPlayer and AnimationTree APIs have been partially unified via a common AnimationMixer base class, solving a number of issues in the process (GH-80813). The C# integration received a number of improvements, both in the bindings (GH-81101, GH-81783), language interoperability (GH-67304), backward compatibility (GH-80527), and editor UX (GH-80260). The GDExtension team has been wrapping up their feature work, notably with the long awaited support for hot reloading extensions in the editor (GH-80284), as well as an option to include the class reference in the extension API JSON (GH-82331).
