Godot 4.6 marks a mature, performance-focused release centered on polish and workflow improvements that streamline the entire development process. Check the Godot Official Announcement and the Godot Changelog for more info:

- New Modern editor theme improves readability, focus, and visual clarity.

- Jolt Physics is now the default, production-ready physics engine for new 3D projects.

- Editor docks and panels are now movable, floatable, and fully rearrangeable.

- New modular IK frameworkvfor advanced procedural animation.

- Major SSR overhaul with more realistic reflections and better performance.

- Added LibGodot support to allow embedding Godot into external applications.

- Introduced delta encoding for Patch PCKs to significantly reduce update sizes.

- Direct3D 12 is now the default renderer for new Windows projects, offering better driver stability.

- New joypad foundation for LED control, motion sensors, and haptic feedback.

- Quality-of-life editor updates to streamline scripting, inspector navigation, and overall workflow.

Projects comming from Godot 4.x are almost compatible with Godot 4.6, because this is not a major version (as Godot 3.x to Godot 4.0). For most games and apps made with 4.5 it should be relatively safe to migrate to 4.6, but check the Migration Guide from Godot 4.5 to Godot 4.6 for some breaking changes and the Official Documentation for more info.

Following the release of Godot 4, Godot 3 is maintained as a Long Term Support (LTS) version for a limited period. Support is restricted to critical fixes and occasional backports, while all primary development efforts are now focused on Godot 4.

The Godot Engine is a free and open-source, cross-platform game engine that provides a complete and unified set of tools for creating both 2D and 3D games. It features an intuitive editor, a flexible scene system, and a robust scripting environment, enabling developers to build, test, and deploy games efficiently across multiple platforms!
