Breaking changes:
* [bytes](https://docs.python.org/3/library/stdtypes.html#bytes) annotation (converter) now re-encodes the corresponding parameter back to bytes
Deprecations:
* The `convert_default` argument to [`value_converter`](https://clize.readthedocs.io/en/stable/api.html#clize.parser.value_converter) is now deprecated. [`Parameter.cli_default`](https://clize.readthedocs.io/en/stable/reference.html#clize.Parameter.cli_default) is the recommended replacement. To help transition, a new `convert_default_filter` option has been added to [`value_converter`](https://clize.readthedocs.io/en/stable/api.html#clize.parser.value_converter), which allows converter authors to filter which values are selected for default conversion, thereby not incurring a deprecation warning for the user.
Updated compatibility:
* Dropped support for Python 2.7, Python 3.5.
* Verified support for Python 3.10+
* Compatibility with Docutils 0.21+
* Improved path support for Windows
Improvements:
* Automatically group identical subcommands as aliases
* Evaluate deferred annotations from [PEP 563](https://www.python.org/dev/peps/pep-0563)
* Basic support for [typing.Annotated](https://docs.python.org/3/library/typing.html#typing.Annotated)
* [Parameter.cli_default](https://clize.readthedocs.io/en/stable/reference.html#clize.Parameter.cli_default) allows script writers to specify a default value that will be converted like an argument passed in from the CLI, but not supplied when the function is called from Python.
Process updates:
* Updated Continuous Integration and Delivery to speed up releases and move off of deprecated CI platform.
