Should the #11804 issue be added to this PR as well?

[raulsntos]

Yes. Thanks for letting me know. Included in 519923a.

Heya, could you add a note on godotengine/godot#107679?

I'm not sure how the document is written, but the basic idea is this:

If you use the audio_bus_override feature on Area2D / 3D, AND you use the AudioStreamPlayer default area_mask (just layer 1 ticked), after the update you will need to reset the mask to layer 1 — otherwise, the bus overrides will stop working. If the mask is set to anything except layer 1, it will continue to work as expected.

Thanks, included in 142d191.

These should be included:

• GDScript: Improve evaluation of constant expressions with arrays/dictionaries godot#113228 (cc @dalexeev)
• Fix Jolt integration not converting planes correctly godot#118948 (cc @mihe)

[mihe]

This needs to be included as well, even if the actionable is (unfortunately) just "re-tweak all your soft bodies":

• Jolt SoftBody3D: Make default mass 1 kg and fix stiffness conversion godot#116041

I'll try to draft some section for this and godotengine/godot#118948.

EDIT: Oh, and this as well I guess:

• Add ability for Area3D to detect/influence SoftBody3D with Jolt Physics godot#114198
