## New Features
### astropy.constants
* Added CODATA 2022 support in astropy.constants.
* This update affects the following constants while the rest are
unchanged from CODATA 2018:
- m_p (Proton mass)
- m_n (Neutron mass)
- m_e (Electron mass)
- u (Atomic mass)
- eps0 (Vacuum electric permittivity)
- Ryd (Rydberg constant)
- a0 (Bohr radius)
- muB (Bohr magneton)
- alpha (Fine-structure constant)
- mu0 (Vacuum magnetic permeability)
- sigma_T (Thomson scattering cross-section) [#18118]
### astropy.coordinates
* Allow np.concatenate, np.stack and similar numpy functions to
be applied on representations and differentials.
* They can also be applied to coordinate frames and SkyCoord,
though with the same limitation as for setting elements of
frames and coordinates: all frame attributes have to be scalars
(or arrays with only identical elements). [#18193]
* The results of match_coordinates_3d(), match_coordinates_sky(),
search_around_3d() and search_around_sky() and the
corresponding SkyCoord methods now have named attributes.
[#18459]
### astropy.cosmology
* The trait astropy.cosmology.traits.CurvatureComponent has been

## New Features
### astropy.coordinates
* search_around_sky and search_around_3D now accept
separations/distlimits broadcastable to the same shape as
coords1. [#17824]
### astropy.io.ascii
* Add functionality to read and write to a Table from the TDAT
format as part of the Unified File Read/Write Interface.
[#16780]
* io.ascii now supports on-the-fly decompression of
LZW-compressed files (typically “.Z” extension) via the
optional package uncompresspy. [#17960]
### astropy.io.fits
* Astropy can now not only read but also write headers that have
HIERARCH keys with long values, by allowing the use of CONTINUE
cards for those (as was already the case for regular FITS
keys). [#17748]
* Add strip_spaces option to Table.read to strip trailing
whitespaces in string columns. This will be activated by
default in the next major release. [#17777]
* io.fits now supports on-the-fly decompression of LZW-compressed
files (typically “.Z” extension) via the optional package
uncompresspy. [#17960]
* io.fits now supports on-the-fly decompression of
LZMA-compressed files (typically “.xz” extension) if the lzma
module is provided by the Python installation. [#17968]
### astropy.io.misc
* Add a fast Table CSV reader that uses the PyArrow read_csv()
function. This can be significantly faster and more
OBS-URL: https://build.opensuse.org/package/show/devel:languages:python:numeric/python-astropy?expand=0&rev=150
## API Changes
### astropy.table
* The use of the keyword use_local_files for the js viewer in
astropy.table.Table.show_in_browser is now deprecated.
Starting in Astropy 7.1 this keyword will be ignored and use
of it will issue a warning. The default behavior will be to
use the remote versions of jQuery and DataTables from a CDN.
[#17480]

## Bug Fixes
### astropy.io.fits
* Fix reading zero-width columns such as 0A fields. [#16894]
* Ensure that QTable, like Table, can read zero-length string
columns, and not convert them to length 1 strings. In the
process, avoid a needless copy of all the data for QTable.
[#16898]
### astropy.io.votable
* Fix KeyError when parsing certain VOTables. [#16830]
### astropy.modeling
* Fixed the fit_deriv calculations in the Lorentz1D model.
[#16794]
### astropy.table
* Pretty-printing of Tables now also works in the presence of
zero-length string columns (which sometimes are present in FITS
tables). [#16898]
### astropy.utils
* Fix the return type for np.broadcast_arrays on a single Masked
instance: it now correctly returns a 1-element sequence instead
of a single array, just like would be the case with a regular
array. [#16842]
### astropy.wcs
* Fix a bug where wcs_info_str’s results would look different in
numpy 2 VS numpy 1. [#16586]
## Other Changes and Additions
* The minimum required version of PyArrow is now v7.0.0. [#16785]

* When reading CDS and MRT files, only interpret a line as a
section delimiter if it contains exclusively dashes or equal
signs. This enables rows starting with dashes.
* Fix a spurious exception when reading integer compressed
images with blanks.
* Fixed a crash that occurred for files opened via
fits.open(..., mode='update'), on Windows, and with numpy 2.0
installed. A warning is now emitted in cases most likely to
escalate into undefined behavior (e.g., segfaults), i.e.,
when a closed memory map object is still referenced by
external code. Please report any regression found.
* Fixed a bug that caused models returned by non-linear fitters
to have sync_constraints set to False, which caused
constraints accessed through, e.g., Model.fixed to not be in
sync with the fixed attribute of the parameters.
* Fixed a bug that caused CompoundModel.without_units_for_data
to return an incorrectly constructed model when the compound
model contained a * or / operation, and which also caused
fitting to not work correctly with compound models that
contained * or / operations.
* The OGIP parser is now less restrictive with strings that
represent a unit that includes the sqrt function. For
example, u.Unit("sqrt(m)**3", format="ogip") no longer causes
a ValueError.
* Fixed an edge-case bug in overlap_slices where the function
could return an empty slice for non-overlapping slices.
* Fixed a WCSAxes bug when overlaying a frame with default
units that are not degrees.
OBS-URL: https://build.opensuse.org/package/show/devel:languages:python:numeric/python-astropy?expand=0&rev=131
* Let fitsdiff compare files with lower case HIERARCH keywords
* Fix writing a ``HDUList`` to file when numpy 2 is installed and at least
some of the data is represented as dask arrays.
* Fix display of diff reports with numpy 2.
* Ensure that also zero-length tables preserve whether integer data are
signed or unsigned.
* Fix YAML table serialization compatibility with numpy 2.
* Fix bugs in io.votable related to numpy 2's representation of scalars.
* Ensure that return types from ``sigma_clip`` ``cenfunc`` and ``stdfunc``
are np.float64 for scalar values.
* Ensure structured ``MaskedColumn`` are serialized correctly, including
the mask.
* Fix problems converting Pandas Series to ``Table`` with numpy >=2.0.
* Ensure Time in ymdhms format can also be serialized to files as part of a
table if it is masked.
* Ensure Masked versions of ``np.recarray`` will show the correct class
name of ``MaskedRecarray`` in their ``repr``, and that they will be
serialized correctly if part of a table.
* Fix bugs with how masked structured arrays were represented with numpy 2.
* ``MaskedQuantity`` now works properly with ``np.block``.
* Fix a bug where ``WCSAxes`` could be missing negative signs on axis
labels when using matplotlib's ``usetex`` mode.
* Fix compilation with gcc 14, avoid implicit pointer conversions.
- Drop patch 16450.patch, included upstream.
- Remove upper bound on pytest, no longer required.
OBS-URL: https://build.opensuse.org/package/show/devel:languages:python:numeric/python-astropy?expand=0&rev=124
- Update to 6.1.0
## Highlights
* Updated minimum Python version to 3.10
* Order-dependent angular separations now come with warnings
* io.ascii uses 64-integers by default for integer columns
* Changes to semantics of copy= keyword arguments
* Cosmology is now a dataclass()
## New Features
### astropy.coordinates
* BaseCoordinateFrame now has a position_angle() method, which is
the same as the position_angle method of SkyCoord instances.
[#15737]
* By default the SkyCoord and BaseCoordinateFrame separation()
methods now emit a warning if they have to perform a coordinate
transformation that is not a pure rotation to inform the user
that the angular separation can depend on the direction of the
transformation. It is possible to modify this behaviour with
the new optional keyword-only origin_mismatch argument.
Specifying origin_mismatch="ignore" allows any transformation
to succeed without warning, which has been the behaviour so
far. origin_mismatch="error" forbids all transformations that
are not pure rotations. [#16246]
### astropy.io.ascii
* Clearer error message in reading ASCII tables when there is a
mismatch between converter type and column type. [#15991]
### astropy.io.registry
* The module astropy.io.typing has been added to provide type
annotations for I/O-related functionality. [#15916]
### astropy.samp
* SAMP web profile CORS HTTP server implements Private Network
Access proposal. [#16193]
### astropy.table
* Table now has a setdefault() method, analogous to
dict.setdefault(). [#16188]
### astropy.units
* Added a new module astropy.units.typing that provides support
for type annotations related to astropy.units. [#15860]
* Added a new CGS unit Oersted. [#15962]
* Added “surface brightness”, “surface brightness wav”, “photon
surface brightness”, and “photon surface brightness wav” to
recognized physical types. [#16032]
* Added magnetic helicity as a physical type. [#16101]
### astropy.utils
* For gufuncs on Masked instances, add support for the axes
argument. [#16121]
* Masked instances now support the various numpy array set
operations, such as np.unique and np.isin. [#16224]
### astropy.wcs
* Added support for slicing WCS objects containing cpdis or
det2im distortions, which previously were ignored. [#16163]
## API Changes
### astropy.coordinates
* The astropy.coordinates.transformations module has been
refactored into a module. There should be no user-visible
changes, but if you notice any, please open an Issue. [#15895]
* Changed the default value of the copy argument in
astropy.coordinates.representation.CylindricalDifferential.__init__
from False to True, which is the intended behaviour for all
subclasses of
astropy.coordinates.representation.BaseDifferential. [#16198]
### astropy.cosmology
* Cosmology and its subclasses are now frozen dataclass objects.
[#15484]
* The argument verbose in the function z_at_value is now
keyword-only. [#15855]
### astropy.io.ascii
* The io.ascii Python and C table readers were updated to use a
64-bit integer field by default when reading a column of
integer numeric data. This changes the default behavior on
Windows and potentially 32-bit architectures. Previously on
those platforms, table columns with any long integers which
overflowed the 32-bit integer would be returned as string
columns. The new default behavior is consistent with numpy v2
and pandas. [#16005]
* The parallel fast-reader parser for reading ASCII files has
been removed. Since astropy v4.0.4 requesting this option has
issued a warning that this option is broken and that the serial
parser will be used. The parallel key in the fast_reader
argument for reading ASCII tables is no longer available.
[#16103]
### astropy.table
* show_in_notebook is deprecated and it is recommended to use
dedicated tools in the Jupyter ecosystem to create interactive
plots in notebooks. [#15905]
* A warning is now emitted when Quantity values are inserted into
empty Column objects via Table.insert_row or Table.add_row.
[#16038]
* show_in_browser is deprecated (pending feedback from the
community). Please use astropy/astropy#16067 if you are
actively using the function. [#16068]
* TableColumns.setdefault() and TableColumns.update() methods
(which would typically be called as Table.columns.setdefault()
and Table.columns.update()) have been deprecated because they
can easily corrupt the Table instance the TableColumns instance
is attached to. The Table.setdefault() and Table.update()
methods are safe. [#16154]
### astropy.time
* TIME_FORMATS and TIME_DELTA_FORMATS in astropy.time.formats are
changed from OrderedDict to Python dict. [#15491]
* A FutureWarning is now emitted when mutating Time.location
post-initialization. [#16063]
* Following the removal of np.ndarray.ptp in Numpy v2, Time.ptp
is now deprecated in favor of np.ptp. [#16212]
### astropy.units
* If any iterable such as a list of tuple was input to Quantity,
a check was done to see if they contained only quantities, and,
if so, the quantities were concatenated. This makes sense for
list and tuple, but is not necessarily logical for all
iterables and indeed was broken for those that do not have a
length (such as array_api array instances). Hence, the check
will now be done only for values where it makes sense, i.e.,
instances of list and tuple. [#15752]
* Units now exposes get_converter which returns a function that
will convert a scalar or array from one unit to another. This
can be useful to speed up code that converts many quantities
with the same unit to another one, especially if the quantity
has not many elements, so that the overhead of creating a
conversion function is relatively large. [#16139]
### astropy.utils
* Deprecate importing ErfaError and ErfaWarning from
astropy.utils.exceptions. They should be imported directly from
erfa instead. [#15777]
* introspection.isinstancemethod() and
introspection.find_mod_objs() are deprecated. [#15934]
* astropy.utils.console.terminal_size is now deprecated in favour
of shutil.get_terminal_size from the standard library. [#16045]
* indent() is deprecated. Use textwrap.indent() from Python
standard library instead. [#16223]
* Unmasked Masked scalar instances are now considered hashable,
to match the implicit behaviour of regular arrays, where if an
operation leads to a scalar, a hashable array scalar is
returned. [#16224]
### astropy.visualization
* Renamed the min_cut and max_cut keywords in simple_norm and
fits2bitmap to vmin and vmax. The old names are deprecated.
[#15621]
* If vmin == vmax, the ImageNormalize class now maps the input
data to 0. If vmin > vmax, the ImageNormalize class now raises
a ValueError. [#15622]
## Bug Fixes
### astropy.convolution
* Avoid a segfault when calling astropy.convolution.convolve on
an empty array. An exception is now raised instead. [#15840]
### astropy.coordinates
* Previously passing a SkyCoord instance to the
BaseCoordinateFrame separation() or separation_3d() methods
could produce wrong results, depending on what additional frame
attributes were defined on the SkyCoord, but now SkyCoord input
can be used safely. [#15659]
* Distance now accepts as parallax any angle-like value. This
includes types like Column which have a unit but are not
Quantity subclasses. [#15712]
* The new default for the class method SkyCoord.from_name() is to
look for coordinates first in SIMBAD, then in NED, and then in
VizieR, instead of having no specific order. [#16046]
* Fix Angle.to_string() for angles in degrees represented in
‘hms’ and angles in hours represented in ‘dms’. [#16085]
* Fix a bug where SkyCoord.spherical_offsets_by would crash when
a wrap was needed. [#16241]
* search_around_3d() now always raises a UnitConversionError if
the units of the distances in coord1 and coord2 and the unit of
distlimit do not agree. Previously the error was not raised if
at least one of the coordinates was empty. [#16280]
### astropy.cosmology
* Fixed a bug where the attribute ParametersAttribute.attr_name
could be None instead of a string. [#15882]
### astropy.io.ascii
* Reading of CDS header files with multi-line descriptions where
the continued line started with a number was broken. This is
now fixed. [#15617]
* Ensure that the names of mixin columns are properly propagated
as labels for the MRT format. [#15848]
* Fixed reading IPAC tables for long column type on some
platforms, e.g., Windows. [#16005]
### astropy.io.fits
* Avoid WinError 1455 in opening some large files with memory
mapping on windows. [#15388]
* Fix TDISP parsing for floating numbers. [#16007]
* Fix a crash when calling FITS writeto methods with stdout as
the output stream. [#16008]
* Fix TDISP parsing for floating numbers in formats ES / EN.
[#16015]
* Fix conversion of Table to BinTableHDU with
character_as_bytes=True. [#16358]
* Improved error message when instantiating a fits table with an
ill-formed array. [#16363]
### astropy.io.misc
* Reading an empty table stored in parquet format now creates an
empty table instead of raising an unexpected error. [#16237]
### astropy.io.votable
* When reading a VOTable, if some user-requested columns were not
present then the resulting error message previously listed all
the requested column names. Now only columns that are actually
missing are shown. [#15956]
### astropy.stats
* Fix a spurious warning when calling sigma_clipped_stats on a
MaskedColumn. [#15844]
### astropy.table
* Fix a Table bug when setting items (via slice or index list) in
a bytes type MaskedColumn would cause the column mask to be set
to all False. A common way to trigger this bug was reading a
FITS file with masked string data and then sorting the table.
[#15669]
* Fix slicing logic for Row. Previously, slicing a
astropy.table.row.Row object would incorrectly return a column,
now it correctly returns a list of values from that row.
[#15733]
* Fix a ValueError raised by table.join when fed with large
tables. This would typically happen in situations when the
result joined table would be too large to fit in memory. In
those situations, the error message is now much more clearly
about the necessary memory size. [#15734]
* Fix an unintended exception being raised when attempting to
compare two unequal Table instances. [#15845]
* Ensure that if a Column is initialized with a Quantity it will
use by default a possible name defined on the quantity’s .info.
[#15848]
* Fix a bug where columns with dtype=object wouldn’t be properly
deep-copied using copy.deepcopy. [#15871]
* Fix hasattr(Table, "iloc") raising an exception, preventing use
of tables e.g. with scikit-learn. [#15913]
* Calling Table.group_by on an empty table no longer raises an
exception. [#16093]
* The unit conversion convert_unit_to with MaskedColumn was
broken as it was storing the old unit in a dictionary attached
to underlying np.ma.MaskedArray. This fixes it by overwriting
the old unit after unit conversion. [#16118]
* astropy.table.vstack will no longer modify the input list even
when it contains non-Table objects like astropy.table.Row.
[#16130]
* Update old dataTables.js version. This should not affect the
end user. [#16315]
### astropy.time
* Fix comparing NaN Quantity with TimeDelta object. [#15830]
* Scalar Time instances are now hashable if they are not masked,
also if one uses Masked internally, matching the behaviour
prior to astropy 6.0 (and the current behaviour when masking
using np.ma.MaskedArray). [#16224]
### astropy.units
* Fix rare signature incompatibilities between helper and helped
array functions. Most involve cases where the corresponding
numpy function has had its arguments renamed between numpy
versions. Since all those generally changed the first
arguments, which are typically passed as positional arguments,
this should not affect user code. Affected functions: -
numpy.array_str - numpy.choose - numpy.convolve -
numpy.correlate - numpy.histogram - numpy.histogramdd -
numpy.histogram2d - numpy.isin - numpy.inner - numpy.nanmedian
- numpy.unique - numpy.matrix_rank - numpy.unwrap - numpy.vdot
- numpy.lib.recfunctions.unstructured_to_structured [#15710]
* Fix an issue with unicode string representations of units shown
as superscripts (like degree) when raised to some power. Like
for LaTeX representations, now the superscript unicode
character is replaced by the literal short name before adding
the power. [#15755]
* Fix a missing Sun unit in the list of VOUnits simple_units.
[#15832]
* Fix an unhelpful TypeError when attempting truediv, lshift (<<)
or mul (*) or truediv (/) with a Unit for right operand and a
numpy array with non-numerical dtype for left operand. [#15883]
* Fix write/read roundtrips with empty Table dumped to ECSV.
[#15885]
* Fix a bug where LaTeX formatter would return empty strings for
unity (1) input. [#15923]
* Fix extraneous space in LaTeX repr for Quantity objects with
superscript units (e.g. angles or temperatures in degree
Celsius). [#16043]
* Ensure powers of units are consistently as simple as possible.
So, an integer if possible, otherwise a float, or a fraction if
the float is really close to that. This also ensures the hash
of a unit is unique for any given unit (previously, the same
power could be represented as float, int or fraction, which
made the hash different). [#16058]
* Ensure that find_equivalent_units only returns actual units,
not units that raised to some power match the requested one.
With this fix, (u.m**-3).find_equivalent_units() properly finds
nothing, rather than all units of length. [#16127]
* Using a dimensionless Quantity as an exponent works anew. In
astropy 6.0.1 an exception was erroneously raised. [#16261]
### astropy.utils
* Fix rare signature incompatibilities between helper and helped
array functions. These typically cover corner cases and should
not affect user code. Some arguments weren’t being re-exposed
correctly or at all, depending on numpy’s version. Affected
functions: - numpy.broadcast_arrays - numpy.median -
numpy.quantile - numpy.empty_like - numpy.ones_like -
numpy.zeros_like - numpy.full_like [#16025]
* Fix a bug where astropy.utils.console.Spinner would leak
newlines for messages longer than terminal width. [#16040]
* Update report_diff_values so the diff no longer depends on the
console terminal size. [#16065]
* Fix support in Masked for generalized ufuncs with more than a
single core dimension (such as erfa.rxp). [#16120]
* Masked array instances now deal more properly with structured
dtypes, combining field masks to get element masks for
generalized ufuncs, and allowing .view() any time the mask can
be viewed as well. This allows a larger number of erfa routines
to work with masked data. [#16125]
### astropy.visualization
* WCSAxes will correctly set certain defaults when
wcs.world_axis_physical_types contains custom: prefixes.
[#15626]
* Fix an edge case where quantity_support would produce duplicate
tick labels for small data ranges. [#15841]
* Fix a bug where AngleFormatterLocator and
ScalarFormatterLocator wouldn’t respect matplotlib.rc’s
axes.unicode_minus parameter. [#15902]
* Fixed a bug in CoordinateHelper.grid method to properly handle
draw_grid=False and draw_grid=None, ensuring grid lines are
controlled correctly even when not explicitly called. [#15985]
### astropy.wcs
* Updated bundled WCSLIB version to 8.2.2. This update fixes
character buffer overflows in the comment string for the
longitude and latitude axes triggered by some projections in
wcshdo(), and also the formatting for generic coordinate
systems. For a full list of changes - see
http://www.atnf.csiro.au/people/mcalabre/WCS/CHANGES or
astropy/cextern/wcslib/CHANGES [#15795]
* Fixed a bug in fit_wcs_from_points that does not set the
default value of the cdelt of the returned WCS object. [#16027]
* Fixed a bug in DistortionLookupTable (which implements cpdis
and det2im projection corrections to a WCS) in which image
pixels received an incorrect distortion value, from a location
in the lookup table incorrectly offset by about 1 table pixel.
[#16163]
## Other Changes and Additions
* Update minimum supported Python version to 3.10 [#15603]
* The minimum required NumPy version is now 1.23 and the minimum
required SciPy version is 1.8. [#15706]
* Fix loading parser tabs on pyc-only installations.
* Fix a bug in the wrappers for the lex and yacc wrappers that
are used for parsing Astropy units so that they work on
pyc-only installations.
* According to the Python module loading flow chart, when
evaluating import foo and foo.py is not found, Python then
reads foo.pyc.
* One can take advantage of this fact to strip source files and
leave only Python bytecode files for deployment
inspace-constrained execution environments such as AWS Lambda.
Astropy is now compatible with pyc-only deployments. [#16159]
* Change the default value of copy arguments in public APIs from
False to None if Numpy 2.0 or newer is installed. For details,
see the “Copy semantics” section on the What’s New page for
Astropy 6.1 . [#16181]

- Update to 6.0.0
## New Features
### astropy.config
* The new ConfigNamespace.help() method provides a convenient way
to get information about configuration items. [#13499]
### astropy.coordinates
* Support has been added to create geodetic representations not
just for existing ellipsoids from ERFA, but also with
explicitly provided values, by defining a subclass of
BaseGeodeticRepresentation with the equatorial radius and
flattening assigned to _equatorial_radius and _flattening
attributes. [#14763]
* Add BaseBodycentricRepresentation, a new spheroidal
representation for bodycentric latitudes and longitudes.
[#14851]
* Support Numpy broadcasting over frame data and attributes.
[#15121]
### astropy.cosmology
* Registered a latex writer for exporting a Cosmology object to a
LaTex table. [#14701]
* Added argument rename to Cosmology’s I/O, allowing for input
and output symbols to be renamed. [#14780]
* All non-abstract Cosmology subclasses are now automatically
registered to work with Astropy’s YAML serialization. [#14979]
* Cosmology I/O now auto-identifies the ‘.tex’ suffix with the
‘ascii.latex’ format. [#15088]
* The Cosmology class now has a new property to access the
parameters of the cosmology: .parameters. This property return
a read-only dictionary of all the non-derived parameter values
on the cosmology object. When accessed from the class (not an

## Bug Fixes
### astropy.io.misc
* Updated ``astropy.io.misc.yaml`` so ``dump()` with a numpy
object array or ``load()`` with YAML representing a Numpy
object array both raise ``TypeError``. This prevents problems
like a segmentation fault. [#15373]
### astropy.io.votable
* Fixed a bug in ``convert_to_writable_filelike`` where
``GzipFile`` was not closed properly. [#15359]
### astropy.units
* In VOUnit, the spaces around the slash were removed in the
formatting of fractions, and fractional powers now also use the
"**" operator. [#15282]
* We now ensure that the unit ``u.cgs.cm`` is just an alias of
``u.si.cm``, instead of a redefinition. This ensures that
``u.Unit("cm") / u.cm`` will reliably cancel to dimensionless
(instead of some "cm / cm"). [#15368]
### astropy.utils
* For ``Masked``, ``np.ptp`` and the ``.ptp()`` method now
properly account for the mask, ensuring the result is identical
to subtracting the maximum and minimum (with the same
arguments). [#15380]
## Other Changes and Additions
* Compatibility with Python 3.12. [#14784]
* Replaced the URL of ``IETF_LEAP_SECOND_URL`` because the
original is now defunct and IETF now defers to IANA for such
look-up. [#15421]
OBS-URL: https://build.opensuse.org/package/show/devel:languages:python:numeric/python-astropy?expand=0&rev=104
## Bug Fixes
### astropy.coordinates
* TransformGraph.to_dot_graph() now throws an exception for
invalid savelayout.
### astropy.cosmology
* The exponent of w0wzCDM functions in inv_efunc has been
corrected to 3, from -3. [#15224]
### astropy.modeling
* Astropy modeling can filter non-finite data values using the
filter_non_finite keyword argument in a fitter call. Now when
filter_non_finite is True, non-finite weights will also be
filtered to prevent crashes in LevMarLSQFitter. [#15215]
### astropy.units
* Fixed astropy.units.Quantity’s implementation of
numpy.nanmedian(), where for Numpy >= 1.25 an exception was
raised for some array shapes and axis combinations. [#15228]
## Other Changes and Additions
* v5.3.x will not support NumPy 2.0 or later. [#15234]
OBS-URL: https://build.opensuse.org/package/show/devel:languages:python:numeric/python-astropy?expand=0&rev=100
* The exponent in ``wowzCDM.de_density_scale`` has been
corrected to 3, from -3.
* Fix crash when a PrimaryHDU has a GROUPS keyword with a non-
boolean value (i.e. not a random-groups HDU).
* Fixed a bug that caused ``Cutout2D`` to not work correctly
with ``CompImageHDU.section``
* Fixed a bug that caused compressed images with TFORM missing
the optional '1' prefix to not be readable. [#15001]
* Restore bitmask propagation behavior in ``NDData.mask``, plus
a fix for arithmetic between masked and unmasked ``NDData``
objects.
* Fix a bug where table indexes were not using a stable sort
order. This was causing the order of rows within groups to
not match the original table order when an indexed table
was grouped. [#14907]
* In VOunits, "pix", "au", "a", and "ct" are removed from the
list of deprecated units. [#14885]
OBS-URL: https://build.opensuse.org/package/show/devel:languages:python:numeric/python-astropy?expand=0&rev=96
* New flat astropy.cosmology classes
* New union operators for Table
* Efficient data access for compressed FITS files
* Added support for NOCOMPRESS for compressed FITS files
* New fraction option for representing units as strings
* Change in order in unit string representations
* Support for collapse operations on arbitrary axes in nddata
* Refresh cached observatory site registry for EarthLocation
methods
* Support for collapse operations on arbitrary axes in nddata
* New LombScargleMultiband class for multiband datasets

- Update to 5.2.2
## Bug Fixes
### astropy.io.ascii
* CDS and MRT tables with units that contain with multiple
divisions, such as km/s/Mpc now parse correctly as being equal
to km/(s.Mpc). [#14369]
### astropy.io.fits
* Fix FITSDiff when table contains a VLA column with the Q type.
[#14539]
### astropy.table
* Fix a bug when creating a QTable when a Quantity input column
is present and the units argument modifies the unit of that
column. This now works as expected where previously this caused
an exception. [#14357]
### astropy.units
* CDS units with multiple divisions, such as km/s/Mpc now parse
correctly as being equal to km/(s.Mpc). [#14369]
### astropy.wcs
* Fixed a bug that caused subclasses of BaseHighLevelWCS and
HighLevelWCSMixin to not work correctly under certain
conditions if they did not have world_n_dim and pixel_n_dim
defined on them. [#14495]

- Update to 5.2.1
## Bug Fixes
### astropy.coordinates
* Fix to ITRS frame earth_location attribute to give the correct
result for a topocentric frame. [#14180]
### astropy.cosmology
* Bounds are no longer passed to the scipy minimizer for methods
Brent and Golden. The scipy minimizer never used the bounds but
silently accepted them. In scipy v1.11.0.dev0+ an error is
raised, so we now pass None as the bounds to the minimizer.
Users should not be affected by this change. [#14232]
### astropy.io.fits
* Tables with multidimensional variable length array can now be
properly read and written. [#13417]
### astropy.units
* Modified the behavior of numpy.histogram(),
numpy.histogram_bin_edges(), numpy.histogram2d(), and
numpy.histogramdd() so that the range argument must a
compatible instance of astropy.units.Quantity if the other
arguments are instances of astropy.units.Quantity. [#14213]
### astropy.visualization
* Improved the performance of drawing WCSAxes grids by skipping
some unnecessary computations. [#14164]
* Fixed WCSAxes sometimes triggering a NumPy RuntimeWarning when
determining the coordinate range of the axes. [#14211]
## Other Changes and Additions
* Fix compatibility with Numpy 1.24. [#14193]

# API Changes
## astropy.wcs
* The pixel argument to
astropy.visualization.wcsaxes.ticklabels.TickLabels.add no
longer does anything, is deprecated, and will be removed in a
future astropy version. It has been replaced by a new required
data argument, which should be used to specify the data
coordinates of the tick label being added.
* This changes has been made because it is (in general) not
possible to correctly calculate pixel coordinates before
Matplotlib is drawing a figure. [#12630]
# Bug Fixes
## astropy.coordinates
* Fixed a bug that prevented SkyOffsetFrame instances to be
pickled by adding a custom __reduce__ method to the class (see
issue #9249). [#13305]
* Fixed the check for invalid Latitude values for float32 values.
Latitude now accepts the float32 value of pi/2, which was
rejected before because a comparison was made using the
slightly smaller float64 representation. See issue #13708.
[#13745]
## astropy.io.ascii
* Fixed confusing chained exception messages of read() function
when it fails. [#13170]
* When writing out a :class:`~astropy.table.Table` to HTML
format, the formats keyword argument to the
:meth:`~astropy.table.Table.write` method will now be applied.

# Bug Fixes
## astropy.modeling
* Fixed the Gaussian2D bounding_box when theta is an angular
Quantity. [#13021]
## astropy.utils
* Reverted astropy.utils.iers.iers.IERS_A_URL to
maia.usno.navy.mil domain instead of NASA FTP to work around
server issues. [#13004]
# Other Changes and Additions
* Updated bundled WCSLIB to version 7.9 with several bugfixes and
added support for time coordinate axes in wcsset() and
wcssub(). The four-digit type code for the time axis will have
the first digit set to 4, i.e., four digit code will be 4xxx
where x is a digit 0-9. For a full list of bug fixes see

# Bug Fixes
## astropy.convolution
* Bugfix in astropy.convolution.utils.discretize_model which
allows the function to handle a CompoundModel. Before this fix,
discretize_model was confusing CompoundModel with a callable
function. [#12959]
## astropy.io.fits
* Fix write and read FITS tables with multidimensional items,
using from_columns without previousely defined ColDefs
structure. [#12863]
## astropy.io.votable
* Fix VOTable linting to avoid use of shell option. [#12985]
astropy.utils
* Fix XML linting to avoid use of shell option. [#12985]

astropy.io.ascii
* Bugfix to add backwards compatibility for reading ECSV version
0.9 files with non-standard column datatypes (such as `object`,
`str`, `datetime64`, etc.), which would raise a ValueError in
ECSV version 1.0. [#12880]
* astropy.io.misc
* Bugfix for `units_mapping` schema's property name conflicts.
Changes:
- `inputs` to `unit_inputs`
- `outputs` to `unit_outputs` [#12800]
astropy.io.votable
* Fixed a bug where `astropy.io.votable.validate` was printing
output to `sys.stdout` when the `output` paramter was set to
`None`. `validate` now returns a string when `output` is set to
`None`, as documented. [#12604]
astropy.modeling
* Fix handling of units on `scale` parameter in BlackBody model.
[#12318]
* Indexing on models can now be used with all types of integers
(like `numpy.int64`) instead of just `int`. [#12561]
* Fix computation of the separability of a `CompoundModel` where
another `CompoundModel` is on the right hand side of the `&`
operator. [#12907]
* Provide a hook (`Model._calculate_separability_matrix`) to
allow subclasses of `Model` to define how to compute their
separability matrix. [#12900]
astropy.stats
* Fixed a bug in which running
`kuiper_false_positive_probability(D,N)` on distributions with
many data points could produce NaN values for the false
positive probability of the Kuiper statistic. [#12896]
astropy.wcs
* Fixed a bug due to which `naxis`, `pixel_shape`, and
`pixel_bounds` attributes of `astropy.wcs.WCS` were not
restored when an `astropy.wcs.WCS` object was unpickled. This
fix also eliminates `FITSFixedWarning` warning issued during
unpiclikng of the WCS objects related to the number of axes.
This fix also eliminates errors when unpickling WCS objects
originally created using non-default values for `key`,
`colsel`, and `keysel` parameters. [#12844]
