Hi everyone! I released an online tool to provide a range of compatible Unity versions for a given API. Very similar to what Sabresaurus did (https://sabresaurus.com/unity-api-versioner/). Unfortunately, this service is not maintained anymore. https://ngtools.tech/uv/ With a UI rather simple: A lot of good stuff in there! Searching through the whole codebase: See the derived Types : Unlike Sabresaurus, NG Unity Versioner handles internal API as well! Enjoy!
