This release makes some big changes. With the release of Blender 4.2, Blender is deprecating addons and replacing them with extensions. Extensions require you to bundle any wheels you use in the zip file, so the build process had to be reworked.
Large parts of Parrot ended up being rewritten, including the core language processing routines. Parrot now uses allosaurus, so it should work with any language and there is no longer a need to install specific language packs.
I was able to test this on Windows, but have not had a chance to try on Linux or Mac. If you use one of those platforms and are running into issues, please file an issue.
The Linux extension was too large to upload. You'll need to build it if you need it.
