Game developers might want to begin to look closer at this one! The free and open source Godot Engine is about to have the biggest update ever with 4.0 that now has a first Release Candidate. Since it's such a massive overhaul it would be close to impossible to list everything that has changed since Godot 3.x!
Just a small slice of what's actually new includes: Vulkan support, sky shaders, a big upgrade to their GDScript language, upgraded .NET for C# scripting, big improvements to importing and exporting assets, lots of improvements to accessibility within the game engine editor, AMD Fidelity FX Super Resolution (FSR) support, a volumetric fog effect was added, a new global illumination system, an improved and refreshed physics system and the list just keeps on going for quite some time.
Right now their focus is set firmly on fixing up issues and making sure it's truly release ready, so no more new features will be pulled in until Godot 4.1.
Hopefully the 4.0 release, and then 4.1 after will keep pulling more people over to this FOSS game engine, rather than getting stuck with proprietary lock-in from Unreal, Unity, Game Maker and other popular game engines.
