0.11.0 (2021-10-12)

• Testing against python 3.10 in github actions and officially noting support
  for 3.10 in setup.py.
• Testing against python 3.9 in github actions and noting support in
  setup.py.
• Fixed an issue where exceptions raised during execution where the task
  completed before TaskGraph.join() was called would not be raised. Now,
  if a task raises an exception, its exception will always be raised when
  either Task.join() and TaskGraph.join() is called.
• Fixed an issue where tasks with hash_algorithm='sizetimestamp' would,
  under certain conditions, fail to re-execute when they should. This only
  occurred when a graph writing the same amount of , but possibly different,
  data is executed successively, with less than about 1.5 seconds between
  task executions.
• After many years with the Natural Capital Project, Rich Sharp has stepped
  down from the Project and as the maintainer of taskgraph. James
  Douglass is taking his place, and this change is now reflected in
  setup.py.
• Fixes an issue that causes an EOFError or BrokenPipeError to occur
  when the TaskGraph terminates.
• Updated the taskgraph example in the README for the latest API changes
  and to clarify the need for if __name__ == '__main__':
• Fixed an issue that could cause the TaskGraph object to hang if
  duplicate Task objects were created.
• Fixed an issue that was causing TaskGraph to ignore a changed
  hash_algorithm if the TaskGraph was created on one run, was
  deconstructed, then restarted. If the user chose a different hash, TaskGraph
  would use the hash that the target file was originally hashed under rather
  than the new algorithm.
• Removed copy_duplicate_artifact and hardlink_allowed parameters
  and functionality from TaskGraph. This is to address a design error that
  TaskGraph is not well suited for caching file results to avoid
  recomputation. Rather than add additional complexity around the limitations
  of this feature it is being removed to guide a design toward a standalone
  cache library if needed.
