+axis coordinates (https://github.com/NCAS-CMS/cf-python/issues/741)
Improve cf.Field.__getitem__ performance by not re-calculating
+axis cyclicity (https://github.com/NCAS-CMS/cf-python/issues/744)
Reduce output CFA netCDF file size by setting the HDF5 chunksizes of +CFA variables to be no larger than required +(https://github.com/NCAS-CMS/cf-python/issues/739)
Allow a halo to be added by cf.Field.indices and
+cf.Field.subspace
+(https://github.com/NCAS-CMS/cf-python/issues/759)
Added spherical regridding to discrete sampling geometry destination +grids (https://github.com/NCAS-CMS/cf-python/issues/716)
Added 3-d spherical regridding to cf.Field.regrids, and the option
+to regrid the vertical axis in logarithmic coordinates to
+cf.Field.regrids and cf.Field.regridc
+(https://github.com/NCAS-CMS/cf-python/issues/715)
New keyword parameter to cf.Field.regrids and cf.Field.regridc:
+return_esmpy_regrid_operator
+(https://github.com/NCAS-CMS/cf-python/issues/766)
New keyword parameters to cf.wi: open_lower and open_upper
+(https://github.com/NCAS-CMS/cf-python/issues/740)
Fix misleading error message when it is not possible to create area
+weights requested from cf.Field.collapse
+(https://github.com/NCAS-CMS/cf-python/issues/731)
Fix bug in cf.read when reading UM files that caused LBPROC value
+131072 (Mean over an ensemble of parallel runs) to be ignored
+(https://github.com/NCAS-CMS/cf-python/issues/737)
Fix bug in cf.aggregate that sometimes put a null transpose
+operation into the Dask graph when one was not needed
+(https://github.com/NCAS-CMS/cf-python/issues/754)
Fix bug in cf.aggregate that caused a failure when property values
+were numpy arrays with two or more elements
+(https://github.com/NCAS-CMS/cf-python/issues/764)
Fix bug in cf.aggregate that didn’t correctly handle the
+“actual_range” CF attribute

Fix bug whereby Field.cyclic is not updated after a
+Field.del_construct operation
+(https://github.com/NCAS-CMS/cf-python/issues/758)
Fix bug that meant cyclic() always returned an empty
+set for domains produced by cf.Field.domain
