Breaking changes

Statistical functions (frequency_analysis, fa, fit, parametric_quantile) are now solely accessible via indices.stats.

New indicators

atmos.degree_days_depassment_date, the day of year when the degree days sum exceeds a threshold.

New features and enhancements

Added unique titles to atmos calculations employing wrapped_partials.
xclim.core.calendar.convert_calendar now accepts a missing argument.
Added xclim.core.calendar.date_range and xclim.core.calendar.date_range_like wrapping pandas' date_range and xarray's cftime_range.
xclim.core.calendar.get_calendar now accepts many different types of data, including datetime object directly.
New module xclim.analog and method xclim.analog.spatial_analogs to compute spatial analogs.
Indicators can now accept dataset in their new ds call argument. Variable arguments (that use the DataArray annotation) can now be given with strings that correspond to variable names in the dataset, and default to their own name.
Clarification to frequency_analysis notebook.
Now officially supporting PEP596 (Python3.9).
New methods xclim.ensembles.change_significance and xclim.ensembles.knutti_sedlacek to qualify climate change agreement among members of an ensemble.

Bug fixes

Fixed bug that prevented the use of xclim.core.missing.MissingBase and subclasses with an indexer and a cftime datetime coordinate.
Fixed issues with metadata handling in statistical indices.
Various small fixes to the documentation (re-establishment of some internally and externally linked documents).

Internal changes

Passing align_on to xclim.core.calendar.convert_calendar without using '360_day' calendars will not raise a warning anymore.
Added formatting utilities for metadata attributes (update_cell_methods, prefix_attrs and unprefix_attrs).
xclim/ensembles.py moved to xclim/ensembles/*.py, splitting stats/creation, reduction and robustness methods.
With the help of the mypy library, added several typing fixes to better identify inputs/outputs, and reduce object type mutations.
Fixed some doctests in ensembles and set_options.
clisops v0.4.0+ is now an optional requirements for non-Windows builds.
New xclim.core.units.str2pint method to convert quantity strings to quantity objects. Main improvement is to make "3 degC days" a valid string that converts to "3 K days".
