* Added Python 3.11 support
* Fix the build for PyPy2 ([116](https://github.com/closeio/ciso8601/pull/116))
* Added missing `fromutc` implementation for `FixedOffset` (113). Thanks davidkraljic
* Removed improper ability to call `FixedOffset`'s `dst`, `tzname` and `utcoffset` without arguments
* Fixed: `datetime.tzname` returns a `str` in Python 2.7, not a `unicode`
* Change `METH_VARARGS` to `METH_O`, enhancing performance. ([130](https://github.com/closeio/ciso8601/pull/130))
* Added support for ISO week dates, ([139](https://github.com/closeio/ciso8601/pull/139))
* Added support for ordinal dates, ([140](https://github.com/closeio/ciso8601/pull/140))
