+  unaffected)
+* Fixes aroung hypothesis parameters
+* Officially support Python 3.11 and 3.12
+* Small updates to test suite to make it work with 3.11 and 3.12 and new

+* Dropped the internal `_rwlock` module as it's unused
+* Added mutation testing to CI, lots of speed-ups to the test suite
+  to make it happen
+* Removal of unnecessary `six.b` literals (Alexandre Detiste)
+
+Deprecations:
+* `int_to_string`, `string_to_int`, and `digest_integer` from `ecdsa.ecdsa`
