- Update to 7.1.0
## 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
memory-efficient than the astropy.io.ascii fast reader. This
new reader can be used with Table.read() by setting
format="pyarrow.csv". [#17706]
### astropy.io.votable
* New module astropy.io.votable.dataorigin to extract Data Origin
information from INFO in VOTable. [#17839]
* CooSys VOTable elements now have a method to_astropy_frame that
returns the corresponding astropy built-in frame, when
possible. [#17999]
### astropy.modeling
* Added a fit_info= keyword argument to parallel_fit_dask to
allow users to preserve fit information from each individual
fit. [#17538]
### astropy.nddata
* Adds a utility class, astropy.nddata.Covariance, used to
construct, access, and store covariance matrices. The class
depends on use of the scipy.sparse module. [#16690]
* Add the limit_rounding_method parameter to Cutout2D,
overlap_slices, extract_array, and add_array to allow users to
specify the rounding method used when calculating the pixel
limits of the cutout. The default method is to use ceil.
[#17876]
### astropy.table
* Document that Table.group_by’s underlying sorting algorithm is
guaranteed to be stable. This reflects behavior that was
already present but undocumented, at least since astropy 6.0 .
[#17676]
### astropy.timeseries
* Downsampling now works correctly also on MaskedColumn and
MaskedQuantity with possibly masked elements. Furthermore, the
type of (Masked) column will now be properly preserved in
downsampling. [#18023]
### astropy.units
* Units with the “micro” prefix can now be imported using "μ" in
the name. For example, the microgram can now be imported with
from astropy.units import μg. [#17651]
* It is now possible to import angström, litre and ohm from
astropy.units using the Å, ℓ and Ω symbols. [#17829]
* Unit conversions between kelvins and degrees Rankine no longer
require the temperature equivalency. [#17985]
### astropy.utils
* Make commonly used Masked subclasses importable for ASDF
support.
* Registered types associated with ASDF converters must be
importable by their fully qualified name. Masked classes are
dynamically created and have apparent names like
astropy.utils.masked.core.MaskedQuantity although they aren’t
actually attributes of this module. Customize module attribute
lookup so that certain commonly used Masked classes are
importable.
* See:
- https://asdf.readthedocs.io/en/latest/asdf/extending/converters.html#entry-point-performance-considerations
- gh#astropy/asdf-astropy#253 [#17685]
* astropy.utils.data.download_file can now recover from a
TimeoutError when given a list of alternative source URLs.
Previously, only URLError exceptions were recoverable. An
exception is still being raised after trying all URLs provided
if none of them could be reached. [#17691]
* utils.data now supports on-the-fly decompression of
LZW-compressed files (typically “.Z” extension) via the
optional package uncompresspy. [#17960]
## API Changes
### astropy.coordinates
* On representations the method get_name has been deprecated in
favor of the class-level attribute name. The method will be
removed in a future release. [#17503]
### astropy.cosmology
* A new public module, astropy.cosmology.io, has been added to
provide support for reading, writing, and converting cosmology
instances.
* The private modules astropy.cosmology.funcs,
astropy.cosmology.parameter, astropy.cosmology.connect,
astropy.cosmology.core, and astropy.cosmology.flrw have been
deprecated. Their functionality remains accessible in the
astropy.cosmology module or in the new astropy.cosmology.io
module. [#17543]
* Comoving distances now accept an optional 2nd argument, where
the two-argument form is the comoving distance between two
redshifts. The one-argument form is the comoving distance from
redshift 0 to the input redshift. [#17701]
* A new public module, astropy.cosmology.traits, has been added
to provide building blocks for custom cosmologies. The
currently available traits are: -
astropy.cosmology.traits.ScaleFactor -
astropy.cosmology.traits.TemperatureCMB [#17702]
### astropy.extern
* Astropy used to bundle the javascript libraries jQuery and
DataTables for interactive (e.g. sorting by column values)
tables using the show_in_browser() method. This bundling
requires relatively large files in astropy itself, for a
relatively minor feature. Furthermore, the astropy developers
are not experts in javascript development, and javascript
libraries many need updates to improve on security
vulnerabilities. This change removes the bundled versions of
jQuery and DataTables from astropy, updates the default version
of the remote URLs to version 2.1.8 of DataTables, and sets the
default for show_in_browser(use_local_files=False) to use the
remote versions in all cases. If the method is called with
use_local_files=True, a warning is displayed and remote version
are used anyway. This may break the use of the method when
working offline, unless the javascript files are cached by the
browser from a previous online session. [#17521]
### astropy.table
* showtable CLI is now deprecated to avoid a name clash on
Debian; use showtable-astropy instead. [#18047]
* Fix issues in the handling of a call like tbl.loc[item] or
tbl.loc_indices[item] and make the behavior consistent with
pandas. Here tbl is a Table or QTable with an index defined.
* If item is an empty list or zero-length np.ndarray or an empty
slice, then previously tbl.loc[item] would raise a KeyError
exception. Now it returns the zero-length table tbl[[]].
* If item is a one-element list like ["foo"], then previously
tbl.loc[item] would return either a Row or a Table with
multiple row, depending on whether the index was unique. Now it
always returns a Table, consistent with behavior for
tbl.loc[[]] and tbl.loc[["foo", "bar"]].
* See astropy/astropy#18051 for more details. [#18051]
### astropy.units
* Passing fraction='multiline' to unit.to_string() will no longer
raise an exception if the given format does not support
multiline fractions, but rather give a warning and use an
inline fraction. [#17374]
* Automatic conversion of a str or bytes instance to a unit when
it is multiplied or divided with an existing unit or quantity
is deprecated. [#17586]
* Accessing the contents of the units.deprecated module now emits
deprecation warnings. The module may be removed in a future
version. [#17929]
### astropy.visualization
* All arguments from simple_norm are marked as future
keyword-only, with the exception of the first two (data and
stretch). A warning is now displayed if any other arguments are
passed positionally. [#17489]
## Bug Fixes
### astropy.io.fits
* Fix possible int overflow in the tile compression C code.
[#17995]
### astropy.io.votable
* In CooSys elements, the system was not checked for votable
version 1.5 [#17999]
### astropy.samp
* Fix setting logging level from the samp_hub command line.
Previously, samp_hub --log-level OFF was documented as
supported but actually caused an exception to be raised. The
patch infers valid choices from the standard library’s logging
module. A CRITICAL level will closely emulate the intended OFF
setting. [#17673]
### astropy.table
* Initializing a Table with rows or data set to [] or a numpy
array with zero size (e.g., np.array([[], []])) is now
equivalent to Table(data=None, ...) and creates a table with no
data values. This allows defining the table names and/or dtype
when creating the table, for instance: Table(rows=[],
names=["a", "b"], dtype=[int, float]). Previously this raised
an exception. [#17717]
* Fix issues in the handling of a call like tbl.loc[item] or
tbl.loc_indices[item] and make the behavior consistent with
pandas. Here tbl is a Table or QTable with an index defined.
* If item is an empty list or zero-length np.ndarray or an empty
slice, then previously tbl.loc[item] would raise a KeyError
exception. Now it returns the zero-length table tbl[[]].
* If item is a one-element list like ["foo"], then previously
tbl.loc[item] would return either a Row or a Table with
multiple row, depending on whether the index was unique. Now it
always returns a Table, consistent with behavior for
tbl.loc[[]] and tbl.loc[["foo", "bar"]].
* See astropy/astropy#18051 for more details. [#18051]
### astropy.timeseries
* Made TimeSeries.from_pandas and BinnedTimeSeries.read more
robust to subclassing. [#17351]
### astropy.units
* For the Angstrom unit in the CDS module, u.cds.Angstrom, the
string representation is now “Angstrom” (instead of “AA”),
consistent with what was always the case for u.Angstrom, and
conformant with the CDS standard. [#17536]
* Previously the string representation of the solMass unit in the
"cds" format depended on whether the unit was imported directly
from units or from units.cds. Although both representations
were valid according to the CDS standard, the inconsistency was
nonetheless needlessly surprising. The representation of
units.cds.solMass has been changed to match the representation
of units.solMass. [#17560]
* The degrees Rankine is now represented as
“$mathrm{{}^{circ}R}$” in the "latex" and "latex_inline"
formats and as “°R” in the "unicode" format. [#18049]
### astropy.utils
* Properly detect invalid LZMA files in utils.data. [#17984]
### astropy.visualization
* Fixed an issue when using plot_coord after slicing the WCS
object coordinates. [#18005]
## Performance Improvements
### astropy.timeseries
* Improved the aggregate_downsample performance using a new
default aggregate_func. [#17574]
### astropy.units
* Converting strings to units with Unit() is now up to 225%
faster. [#17399]
* UnitBase.compose() is now 20% faster. [#17425]
## Other Changes and Additions
* After import astropy, dir(astropy) will now list all
subpackages, including those that have not yet been loaded.
This also means tab completion will work as expected (e.g.,
from astropy.coo<TAB> will expand to from astropy.coordinates).
[#17598]
* Updated bundled WCSLIB version to 8.4, fixing issues in
wcs_chksum and wcs_fletcher32. For a full list of changes - see
astropy/cextern/wcslib/CHANGES. [#17886]

## 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

## Bug Fixes
### astropy.coordinates
* Ensure that coordinates can be transformed to other coordinate
frames also if they have size zero (i.e., hold empty data
arrays). [#17013]
* Longitude and Latitude can no longer be initialized with
strings ending in “N” or “S”, and “E” or “W”, respectively,
since those suggest the other type. [#17132]
* np.nanvar(angle) now produces a Quantity with the correct unit,
rather than raising an exception. [#17239]
* Fix a crash when instantiating Angle (or Latitude, or
Longitude) from a non-numpy array (for instance pyarrow
arrays). [#17263]
### astropy.io.fits
* Fix access to VLA columns after slicing .data. [#16996]

## 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] (forwarded request 1197897 from bnavigator)

* 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.

* 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
instance) the dictionary contains Parameter instances, not the
values. [#15168]
* The field default has been added to Parameter. This can be used
to introspect the default value of a parameter on a cosmology
class e.g. LambdaCDM.H0.default. [#15400]
### astropy.io.fits
* Add new option decompress_in_memory to fits.open, to decompress
the whole file in memory at once, instead of decompressing the
file progressively as data is needed. Default behavior is
better for memory usage but sometimes slow, especially for
files with many small HDUs. [#15501]
### astropy.io.votable
* Add support for Parquet serialization of VOTables. Writing of
this serialization is available with using the new
'votable.parquet' format. [#15281]
* Added MIVOT feature through the MivotBlock class that allows
model annotations reading and writing in VOTable. [#15390]
### astropy.modeling
* Added a GeneralSersic2D model that can have “boxy” or “disky”
isophotes. [#15545]
### astropy.nddata
* A more flexible and/or compact string representation is now
available for NDData objects which visually indicates masked
entries, and provides for better for dask array support.
[#14438]
### astropy.table
* The new Row.get() method, analogous to dict.get(), returns the
value of the specified column from the row if the column
present, otherwise it returns a fallback value, which by
default is None. [#14878]
### astropy.time
* Masked Time instances now use astropy’s own Masked class
internally. This means that Masked input is now properly
recognized, and that masks get propagated also to Quantity
output (such as from a TimeDelta converted to a unit of time),
creating MaskedQuantity instances. [#15231]
* Added a TimeDelta format quantity_str that represents the time
delta as a string with one or more Quantity components. This
format provides a human-readable multi-scale string
representation of a time delta. The default output sub-format
is not considered stable in this release, please see
astropy/astropy#15485 for more information. [#15264]
### astropy.uncertainty
* Uncertainty Distribution now support structured data types, and
as a result it now works also with EarthLocation. [#15304]
* Uncertainty Distribution can now be used inside
representations, which also allows basic support in SkyCoord.
While most calculations work, there are remaining issues. For
instance, the repr does not show that the coordinates are
distributions. [#15395]
### astropy.units
* Add support for gc2gde and gd2gce erfa functions to allow
geodetic representations using equatorial radius and
flattening. [#14729]
### astropy.utils
* The astropy.utils.metadata.MetaData default dictionary can now
be set with the default_factory keyword argument. [#15265]
* astropy.utils.decorators.deprecated now adds the __deprecated__
attribute to the objects it wraps, following the practice in
https://peps.python.org/pep-0702/. [#15310]
### astropy.visualization
* Add WCSAxes.text_coord method to print text using SkyCoord
objects parallel to plotting data points with
WCSAxes.plot_coord. [#14661]
### astropy.wcs
* Support WCS descriptions of basic planetary coordinate frames.
[#14820]
* Updated bundled WCSLIB version to 8.1. This update adds support
planetary keywords A_RADIUS, B_RADIUS, C_RADIUS, BLON_OBS,
BLAT_OBS, and BDIS_OBS in auxprm and adds wcsprm::time to the
wcsprm struct to record the TIME axis. This update also
includes several bug fixes. For a full list of changes - see
http://www.atnf.csiro.au/people/mcalabre/WCS/CHANGES [#15035]
## API Changes
### astropy.config
* Removed deprecated ConfigurationMissingWarning class and
update_default_config function; There are no replacements as
they should no be used anymore. [#15466]
### astropy.convolution
* Invalid kernel arithmetic operations now raise a
KernelArithmeticError instead of a bare Exception. [#14728]
* Added base KernelError error class and removed
DiscretizationError error class (a ValueError will be raised
instead). [#14732]
* discretize_model will now raise a ValueError if
mode='oversample' and factor does not have an integer value.
[#14794]
### astropy.coordinates
* Removed deprecated angle parsing and formatting utilities from
angle_utilities. Use the functions from angle_formats instead.
[#14675]
* The deprecated functionality of initializing Angle or Longitude
from a tuple is no longer supported. [#15205]
* Angle-related classes and functions have been moved within
astropy.coordinates. There is no change to public API as
everything moved should still be imported from
astropy.coordinates, not a sub-module. If you are using private
API, try importing from astropy.coordinates instead. If you
need something that has been moved and is not available in
astropy.coordinates, please open an issue on the Astropy issue
tracker. [#15220]
* It is no longer possible to pass frame classes to the
transform_to() method of a low-level coordinate-frame class. It
is still possible to pass frame instances. The transform_to()
method of the high-level SkyCoord class is unaffected. [#15500]
### astropy.cosmology
* Removed support of importing private constants and functions
from astropy.cosmology.flrw. [#14672]
* Removed deprecated Cosmology Parameter argument fmt. [#14673]
* Removed deprecated vectorize_if_needed and inf_like from
cosmology.utils. [#14677]
* Removed deprecated import paths from astropy.cosmology.core.
[#14782]
* Cosmology Parameter is now a dataclass, and can work with all
of Python’s dataclasses machinery, like field introspection and
type conversion. [#14874]
* A new property – scale_factor0 – has been added to Cosmology
objects. This is the scale factor at redshift 0, and is defined
to be 1.0. [#14931]
* Added registration label ascii.latex to Cosmology IO. [#14938]
* The private module astropy.cosmology.utils has been deprecated.
[#14980]
* Removed deprecated get_cosmology_from_string class method in
default_cosmology; use get instead. [#15467]
### astropy.io.ascii
* Several arguments in functions within astropy.io.ascii have
been deprecated and are either renamed or scheduled to be
removed.
* read(): - Reader will be removed. Instead supply the equivalent
format argument. - Inputter has been renamed to inputter_cls. -
Outputter has been renamed to outputter_cls.
* get_reader(): - Reader has been renamed to reader_cls. -
Inputter has been renamed to inputter_cls. - Outputter has been
renamed to outputter_cls.
* write(): - Writer will be removed. Instead supply the
equivalent format argument.
* get_writer(): - Writer has been renamed to writer_cls. [#14914]
* Removed deprecated astropy.io.ascii.tests.common.raises test
helper; use pytest.raises instead. [#15470]
### astropy.io.fits
* Deprecate _ExtensionHDU and _NonstandardExtHDU (use
ExtensionHDU or NonstandardExtHDU instead). [#15396]
* Remove special handling of TCTYP TCUNI TCRPX TCRVL TCDLT TRPOS
(#7157). [#15396]
* Rename and deprecate TableHDU.update to TableHDU.update_header,
for consistency with ImageHDU. [#15396]
### astropy.io.misc
* Removed deprecated astropy.io.misc.asdf subpackage. Use
asdf-astropy package instead. [#14668]
* fnunpickle and fnpickle are deprecated because they are not
used anywhere within astropy. If you must, use the module from
Python standard library but be advised that pickle is insecure
so you should only unpickle data that you trust. [#15418]
### astropy.io.votable
* Removed deprecated pedantic option from the
astropy.io.votable.table.parse() function and the corresponding
configuration setting. Use the verify option instead. [#14669]
* Class astropy.io.votable.tree.Table has been renamed to
TableElement to avoid sharing the name with
astropy.table.Table. [#15372]
* Fully removed support for version = ‘1.0’ on
VOTableFile__init__() and changed its tests to check correctly.
It was raising a DeprecationWarning and now is raising a
ValueError. [#15490]
### astropy.modeling
* Removed the AliasDict class from modeling.utils. [#12943]
* Creating a model instance with parameters that have
incompatible shapes will now raise a ValueError rather than an
IncompatibleShapeError. [#15209]
* Removal of deprecated code _model_to_fit_params and
_fitter_to_model_params from fitting.py. [#15461]
### astropy.stats
* The BoxLeastSquares, BoxLeastSquaresResults and LombScargle
classes are not available from astropy.stats anymore, they are
now available only from astropy.timeseries. [#15530]
### astropy.tests
* Removed deprecated deprecation, warning, and exception handling
functionality provided by astropy.tests.helper. [#14670]
* astropy.tests.command.FixRemoteDataOption and
astropy.tests.command.AstropyTest are deprecated. They are no
longer necessary after sunsetting astropy-helpers. [#15204]
### astropy.time
* Time has switched to use Masked arrays internally, instead of
indicating masked values using NaN in the internal jd2
attribute. As a result, any output from instances, such as one
gets with, say, the .isot format, will also use Masked by
default.
* For backwards compatibility, a new configuration item,
astropy.time.conf.masked_array_type is introduced which is set
to “astropy” by default (which indicates one wants to use
Masked), but can also be set to “numpy”, in which case
numpy.ma.MaskedArray will be used where possible (essentially,
for all but Quantity). [#15231]
* Changed the TimeDelta init signature to be consistent with that
of Time. Previously the argument order was val, val2, format,
scale, copy. Now the order is val, val2, format, scale, *,
precision, in_subfmt, out_subfmt, copy, where the arguments
after the * must be specified by keyword. [#15264]
### astropy.timeseries
* Removed deprecated midpoint_epoch in fold function; use
epoch_time instead. [#15462]
### astropy.uncertainty
* The .dtype attribute exposed by Distribution is now that of the
samples, rather than one that has a “samples” entry. This makes
quantities with structured data types and units easier to
support, and generally makes the Distribution appear more
similar to regular arrays. It should have little effect on
code. For instance, distribution["samples"] still will return
the actual distribution.
* As a consequence of this refactoring, most arrays that are not
C-contiguous can now be viewed and will thus not be copied on
input any more. The only exceptions are arrays for which the
strides are negative.
* Note that the true data type is considered an implementation
detail. But for reference, it now is a structured data type
with a single field, “samples”, which itself is an array of
“sample” fields, which contain the actual data. [#15304]
### astropy.units
* Like np.ndarray, under numpy 2.0 Quantity and all its
subclasses (Angle, Masked, etc.) will no longer support the
.ptp() method. Use np.ptp(...) instead.
* Similarly, support for the much less frequently used
.newbyteorder() and .itemset() methods has been removed.
[#15378]
* The following deprecated functionality has been removed:
- littleh unit and with_H0 equivalency. They are still
available from cosmology.units.
- brightness_temperature equivalency no longer automatically
swaps the order of its arguments if it does not match the
expectation.
- PhysicalType no longer supports str methods and attributes.
[#15514]
### astropy.utils
* Removed deprecated OrderedDescriptor,
OrderedDescriptorContainer, and set_locale in
astropy.utils.misc. [#14679]
* is_path_hidden() and walk_skip_hidden() are deprecated.
[#14759]
* The structure of utils.metadata has been refactored, but all
the available functions and classes are still present and
should be imported as before. [#15166]
* The astropy.utils.metadata.MetaData class, which is used
throughout astropy to carry metadata on tables, columns, etc.,
can now also be used on dataclasses.
* When accessing the meta attribute on a class
astropy.utils.metadata.MetaData now returns None instead of
itself. [#15237]
* The astropy.utils.metadata.MetaData class, which is used
throughout astropy to carry metadata on tables, columns, etc.,
can now also be used on frozen dataclasses. [#15404]
* Removed deprecated version_path in minversion function; it is
no longer used. [#15468]
### astropy.visualization
* The bboxes, ticklabels_bbox, and tick_out_size arguments to
astropy.visualization.wcaxes.ticklabels.TickLabels.draw() now
have no effect and are deprecated. This is to allow rasterized
ticks to be drawn correctly on WCSAxes. [#14760]
* It is now not possible to pass any keyword arguments to
astropy.visualization.wcsaxes.WCSAxes.draw(). Previously
passing any keyword arguments would have errored anyway, as
matplotlib.axes.Axes.draw() does not accept keyword arguments.
[#14772]
* Deprecated the exp attribute in the LogStretch,
InvertedLogStretch, PowerDistStretch, and
InvertedPowerDistStretch stretch classes, and the power
attribute in the PowerStretch. Instead, use the a attribute,
which matches the input keyword. [#15538]
* Removed the maximum value of the a parameter in the
AsinhStretch and SinhStretch stretch classes. [#15539]
### astropy.wcs
* Removed deprecated accuracy from all_world2pix method in WCS;
use tolerance instead. [#15464]
* NoConvergence no longer accepts arbitrary keyword arguments.
[#15504]
## Bug Fixes
### astropy.coordinates
* Fixed minor bug when getting solar system positions of objects
from Type 3 SPICE kernel files. [#15612]
### astropy.cosmology
* The exponent in w0wzCDM.de_density_scale has been corrected to
3, from -3. This correction has also been made to the scalar
inv_efunc cpython functions. [#14991]
* pandas.Series are now uniformly converted to their underlying
data type when given as an argument to a Cosmology method.
[#15600]
### astropy.io.fits
* Reading a table from FITS now respects the TNULL property of a
column, passing it into the column’s fill_value. [#14723]
* Fix crash when a PrimaryHDU has a GROUPS keyword with a
non-boolean value (i.e. not a random-groups HDU). [#14998]
* Fixed a bug that caused Cutout2D to not work correctly with
CompImageHDU.section [#14999]
* Fixed a bug that caused compressed images with TFORM missing
the optional ‘1’ prefix to not be readable. [#15001]
* Ensure that tables written to FITS with both masked and
unmasked columns roundtrip properly (previously, all integer
columns would become masked if any column was masked). [#15473]
* Fix segfault with error report in tile decompression. [#15489]
### astropy.io.votable
* Output of repr for VOTable instance now clearly shows it is a
VOTable and not generic astropy Table. [#14702]
### astropy.modeling
* All models can be pickled now. [#14902]
### astropy.nddata
* Restore bitmask propagation behavior in NDData.mask, plus a fix
for arithmetic between masked and unmasked NDData objects.
[#14995]
### astropy.table
* Table.as_array now respects the fill_value property of masked
columns. [#14723]
* 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]
* Fixed issue #14964 that when grouping a Table on a mixin column
such as Quantity or Time, the grouped table keys did not
reflect the original column values. For Quantity this meant
that the key values were pure float values without the unit,
while for Time the key values were the pair of jd1 and jd2
float values. [#14966]
### astropy.time
* Ensure that the Time caches of formats and scales do not get
out of sync with the actual data, even if another instance,
holding a view of the data is written to. E.g., if one does t01
= t[:2], and sets t[0] after, it is now guaranteed that
t01.value will correctly reflect that change in value. [#15453]
### astropy.units
* In VOunits, “pix”, “au”, “a”, and “ct” are removed from the
list of deprecated units. [#14885]
### astropy.utils
* Ufuncs with more than 2 operands (such as erfa.dtf2d) now work
also if all inputs are scalars and more than two inputs have
masks. [#15450]
* Ensured that str(masked_array) looks like str(unmasked_array)
also for array scalars. Thus, like regular array scalars, the
precision is ignored for float, and strings do not include
extra quoting. [#15451]
### astropy.visualization
* The location of ticklabels on a WCSAxes is now correctly
calculated when the figure is rasterized. [#14760]
* Fixed a bug where a ValueError would be raised in the
AsinhStretch and SinhStretch classes for valid a parameter
values. [#15539]
### astropy.wcs
* wcs.validate(filename) now properly closes the file handler.
[#15054]
* Fix a regression in custom WCS mapping due to the recent
introduction of Solar System frames. [#15630]
## Other Changes and Additions
* The minimum supported version of NumPy is now 1.22. [#15006]
* Moved International Earth Rotation and Reference Systems (IERS)
and Leap Second files out into standalone astropy-iers-data
package, maintaining full backward-compatibility in the
astropy.utils.iers API. Deprecation warnings may be issued when
certain files are accessed directly. [#14819]
* Switch from using setup.cfg for project configuration to using
pyproject.toml. [#15247]
* Update bundled expat to 2.5.0. [#15585]

- 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

OBS-URL: https://build.opensuse.org/package/show/devel:languages:python:numeric/python-astropy?expand=0&rev=108
- Update to 5.3.4
## 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]
