The first maintenance update to the 4.2 feature branch

Godot 4.2.1 is just released, as the first maintenance update to the 4.2 feature branch.

It fixes a number of platform-specific issues, which should make it easier for everyone to upgrade their Godot 4.1 projects, or start new ones in 4.2. https://godotengine.org/article/maintenance-release-godot-4-2-1/

Have fun!
