- Updated build script (`addons/godot_xterm/native/build.sh`). Git submodules will now be initialized if they haven't already. Moved nix-shell related stuff to a seperate shell.nix file so the same build command can be used on all Linux based OSes.
- Asciicast importer plugin. Enables the import of .cast ([asciicast files v2](https://github.com/asciinema/asciinema/blob/master/doc/asciicast-v2.md)) that can be made using the [asciinema](https://asciinema.org/) terminal session recorder. See the [asciicast scene](/examples/asciicast) for example usage.
