* fix for masked array inputs
* improved performance of the num2date algorithm, in some cases providing
an over 100x speedup
* fix for date2index for select != 'exact' when select='exact' works
* silently change calendar='gregorian' to 'standard' internally,
since 'gregorian' deprecated in CF v1.9
* add "is_leap_year" function
* wheels that work on Apple M1 (arm64) available on pypi.
* added support for "common_year" and "common_years" units for "noleap"
and "365_day" calendars
* check consistency of year arg and has_year_zero kwarg in cftime.datetime
(issue #248). Also assume if has_year_zero not specified it should be True
if year=0. Allow replace method to change has_year_zero. Issue UserWarning
if year set to zero and calendar default is changed from False to True
(so that user is aware the resulting instance will not be CF compliant).
* '360_day' was missing from list of 'idealized' calendars.
* fixed a bug that led to subclasses losing their type identity upon
pickling
* Change default behavior of proleptic_gregorian to has_year_zero=T
(to be consistent with ISO-8601 since CF does not specify the year zero convention
for this calendar). Issue warning when trying to
to create a cftime.datetime instance that is not allowed in CF
* clean-up deprecated calendar specific subclasses
* added string formatting support to `cftime.datetime` objects
(via `cftime.datetime.__format__`)
* add support for astronomical year numbering (including year zero) for
real-world calendars using 'has_year_zero' cftime.datetime kwarg
Default is False for 'real-world' calendars ('julian', 'gregorian'/'standard',
'proleptic_gregorian'). Ignored for idealized calendars like '360_day
