- Drop Python 2 support. We follow the official Python release cycle. Now CI runs for Python 3.6+. For 3.4 and 3.5 everything should still work but consider migration, it shouldn't be hard.
- We've migrated tests on pytest+hypothesis. It helped us to find a lot of bugs.
- Some fixes: a bug in Damerau-Levenshtein, normalization in Smith-Waterman, fix support for some unicode chars in Soundex.
- All classes now accept
externalargument even if they have no known external libs support. - CI and releases are powered by DepHell
