Although the vast majority of contributors are busily working on Godot 4, a small problematic group refuse to stop improving Godot 3. Since [Godot 3.6](/article/godot-3-6-finally-released)'s release in September 2024, we have been working hard on the new feature branch, 3.7.
11+
12+
[Jump to the **Downloads** section.](#downloads)
13+
14+
As usual, you can try it live with the [**online version of the Godot editor**](https://editor.godotengine.org/releases/3.7.alpha1/) updated for this release.
15+
16+
Although a number of features are still in preparation, there have already been a number of improvements since 3.6, so consider this a sneak peak at some of the advances that will be available.
17+
18+
### 3D physics interpolation
19+
20+
In tandem with work on Godot 4.5, the 3D physics interpolation has been rewritten from the ground up.
21+
22+
This has enabled us to fix a number of longstanding bugs and usability issues (particularly with non-interpolated tree branches), as well as more accurately representing pivot relationships which should give a smoother result.
23+
24+
### Mutable audio drivers
25+
26+
While most of you will be making games (with near constant audio), those making applications (as well as the Editor itself) can now benefit from mutable audio via hotswapping the audio driver. This can dramatically reduce CPU (audio is one of the biggest CPU demands in the Editor, despite it rarely playing any sounds!).
27+
28+
This is good news especially for those of you using low power PCs, mobile, or developing using a device with a battery such as a laptop. The CPU use in the Editor (in conjunction with "vital updates only" mode) is now approximately 50x less than Godot 4.
29+
30+
Muting behaviour is fully customizable both for the Editor and the Project, with muting on pause, focus loss and when a period of silence is detected (which automatically switches back on when playing a sound). This is also hoped to help with some longstanding bugs preventing laptops from sleeping.
31+
32+
This is a very experimental feature and will definitely benefit from your feedback on different platforms.
33+
34+
### Core
35+
36+
Thanks to work particularly by [lawnjelly](https://github.com/lawnjelly) and [Lukas Tenbrink](https://github.com/Ivorforce), much of core has been heavily optimized, including faster access to `ProjectSettings`, faster object casting, move semantics, and use of faster data structures benefiting 2D and 3D.
37+
38+
### Bug fixes and backports
39+
40+
As always, in addition to feature work, there have been a number of bugs fixed, and backports from Godot 4.x. These are detailed in the notes below. Of course the flow is two way. Godot 4.x has also benefitted from a number of new features forward ported from 3.x.
41+
42+

## Bug reports
209+
210+
As a tester, you are encouraged to [open bug reports](https://github.com/godotengine/godot/issues) if you experience issues with 3.7 alpha 1. Please check first the [existing issues on GitHub](https://github.com/godotengine/godot/issues), using the search function with relevant keywords, to ensure that the bug you experience is not known already.
211+
212+
In particular, any change that would cause a regression in your projects is very important to report (e.g. if something that worked fine in 3.6 or earlier 3.5.x releases no longer works in 3.7 alpha 1).
213+
214+
## Support
215+
216+
Godot is a non-profit, open source game engine developed by hundreds of contributors on their free time, and a handful of part or full-time developers, hired thanks to [donations from the Godot community](/donate). A big thankyou to everyone who has contributed [their time](https://github.com/godotengine/godot/blob/master/AUTHORS.md) or [financial support](https://github.com/godotengine/godot/blob/master/DONORS.md) to the project!
