- Update to version 4.2.1
astropy.cosmology
* Fixed an issue where specializations of the comoving distance
calculation for certain cosmologies could not handle redshift
arrays. [#10980]
astropy.io.fits
* Fix bug where manual fixes to invalid header cards were not
preserved when saving a FITS file. [#11108]
astropy.io.votable
* NumericArray converter now properly broadcasts scalar mask to
array. [#11157]
astropy.table
* Fix bug when initializing a Table subclass that uses
TableAttribute's. If the data were an instance of the table
then attributes provided in the table initialization call
could be ignored. [#11217]
astropy.time
* Change epoch of TimeUnixTAI ("unix_tai") from
1970-01-01T00:00:00 UTC to 1970-01-01T00:00:00 TAI to match
the intended and documented behaviour. This essentially
changes the resulting times by 8.000082 seconds, the initial
offset between TAI and UTC. [#11249]
astropy.units
* Fixed a bug with the quantity_input decorator where allowing
dimensionless inputs for an argument inadvertently disabled
any checking of compatible units for that argument. [#11283]
astropy.utils
* Fix a bug so that np.shape, np.ndim and np.size again work on
classes that use ShapedLikeNDArray, like representations,
frames, sky coordinates, and times. [#11133] (forwarded request 883882 from bnavigator)
