A few days after RC1 a stable release of Godot 3.1.1 came out. From the release candidate differs only a few fixes:
- reverted FreeType to 2.9.1 because 2.10.0 caused regression;
- fixes in animation window;
- fixes in C# support
This release is especially important for mobile and network games. I wrote more about changes when describe RC1.
