igwn-segments 2.1.0 Changes: - Remove the fallback code to import the Python implementation if importing the C implementation fails. It would be a bug and a performance regression if the import ever failed. - Modernize the test suite and port most of the tests to pytest. - Use ruff to automatically format all of the code. - Build binary wheels for Linux aarch64.
