Highlights

This release brings performance enhancements to reading Zarr datasets, the ability to use numbagg <https://github.com/numbagg/numbagg>_ for reductions, an expansion in API for rolling_exp, fixes two regressions with datetime decoding, and many other bugfixes and improvements. Groupby reductions will also use numbagg if flox>=0.8.1 and numbagg are both installed.
