This is primarily a bugfix release due to changes in Distributed that caused failures in Dask-MPI.

2021.11.0

Improvements for this release:

• We reinstated the --scheduler-port option on the CLI! Yay! Thanks to @jacobtomlinson! (PR #73)
• We added the ability to pass in your own MPI Comm when creating a Dask cluster. That's awesome! Thanks to @joezuntz! (PR #75)
• We fixed a bug related to the --local-directory CLI option which was annoyingly preventing all of our other PRs from passing and therefore being merged. Ugh! Thanks to @kmpaul! (PR #77)
• We also fixed another behavioral issue related to the scheduler_ip argument to the Worker CLI. Thanks to @jacobtomlinson! (PR #79)
• Dask-MPI's documentation is now using the newest and awesomest documentation theme! Yay! Thanks to @jacobtomlinson! (PR #80)
• And finally, we are getting around to modernizing our release process! We've added the automated PyPI release action to Dask-MPI's GitHub workflows! Thanks to @kmpaul and @jacobtomlinson! (PR #81)

Enjoy and thanks for using and contributing to Dask-MPI!
