  * Implement user defined aggregations (#1483)
  * Field access works with non-scalar fields (#1484)
- Update to 0.11.0
  * DataFrames now enforce knowing full metadata (columns, dtypes)
    everywhere. Previously we would operate in an ambiguous state
    when functions lost dtype information (such as apply). Now all
    dataframes always know their dtypes and raise errors asking for
    information if they are unable to infer (which they usually
    can). Some internal attributes like _pd and _pd_nonempty have
    been moved.
  * The internals of the distributed scheduler have been refactored
    to transition tasks between explicit states. This improves
    resilience, reasoning about scheduling, plugin operation, and
    logging. It also makes the scheduler code easier to understand
    for newcomers.
  * Breaking Changes
    + The distributed.s3 and distributed.hdfs namespaces are gone.
      Use protocols in normal methods like read_text('s3://...'
    + Dask.array.reshape now errs in some cases where previously
      it would have create a very large number of tasks
