Scheduled monthly dependency update for October

[pyup-bot]

Update astropy from 5.1.1 to 5.3.3.

Changelog

5.3.2

==========================

Bug Fixes
---------

astropy.coordinates
^^^^^^^^^^^^^^^^^^^

- Fixed import when called with Python ``-OO`` flag. [15037]

astropy.nddata
^^^^^^^^^^^^^^

- Fix for collapse operations on ``NDData`` without masks or units. [15082]

astropy.units
^^^^^^^^^^^^^

- Modified the implementation of ``np.power()`` for instances of ``Quantity`` to
allow any array as the second operand if all its elements have the same value. [15101]

5.3.1

==========================

Bug Fixes
---------

astropy.cosmology
^^^^^^^^^^^^^^^^^

- The exponent in ``wowzCDM.de_density_scale`` has been corrected to 3, from -3. [14991]

astropy.io.fits
^^^^^^^^^^^^^^^

- 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]

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
^^^^^^^^^^^^^

- 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]

astropy.units
^^^^^^^^^^^^^

- In VOunits, "pix", "au", "a", and "ct" are removed from the list of deprecated units. [14885]

5.3

========================

New Features
------------

astropy.coordinates
^^^^^^^^^^^^^^^^^^^

- Add optional parameter ``refresh_cache`` to ``EarthLocation.of_site()`` and
``EarthLocation.get_site_names()`` to force the download of the latest site
registry. [13993]

- Added ``atol`` argument to function ``is_O3`` and ``is_rotation`` in matrix utilities. [14371]

- A new class ``astropy.coordinates.StokesCoord`` has been added to represent world coordinates describing polarization state.
This change introduces a breaking change to the return value of ``astropy.wcs.WCS.pixel_to_world`` where before a ``u.Quantity`` object would be returned containing numerical values representing a Stokes profile now a ``StokesCoord`` object is returned. The previous numerical values can be accessed with ``StokesCoord.value``. [14482]

- Add an optional parameter ``location`` to ``EarthLocation.get_itrs()``
to allow the generation of topocentric ITRS coordinates with respect
to a specific location. [14628]

astropy.cosmology
^^^^^^^^^^^^^^^^^

- Two new cosmologies have been added, ``FlatwpwaCDM`` and ``Flatw0wzCDM``, which are the
flat variants of ``wpwaCDM`` and ``w0wzCDM``, respectively. [12353]

astropy.io.ascii
^^^^^^^^^^^^^^^^

- Add ability to read and write an RST (reStructuredText) ASCII table that
includes additional header rows specifying any or all of the column dtype, unit,
format, and description. This is available via the new ``header_rows`` keyword
argument. [14182]

astropy.io.fits
^^^^^^^^^^^^^^^

- Added support for >3D data in CompImageHDU [14252]

- Added a ``CompImageHDU.section`` property which can be used to
efficiently access subsets of the data, similarly to ``ImageHDU.section``.
When using this, only the tiles required to cover the section are
read from disk and decompressed. [14353]

- Added support for ``'NOCOMPRESS'`` for the ``compression_type`` option in ``CompImageHDU``. [14408]

- Added new properties ``compression_type`` and ``tile_shape`` on
``CompImageHDU``, giving the name of the compression algorithm
and the shape of the tiles in the tiled compression respectively. [14428]

- Do not call ``gc.collect()`` when closing a ``CompImageHDU`` object as it has a
large performance penalty. [14576]

- VLA tables can now be written with the unified I/O interface.
When object types are present or the VLA contains different types a `TypeError`
is thrown. [14578]

astropy.io.misc
^^^^^^^^^^^^^^^

- Add support for writing/reading fixed-size and variable-length array columns to the parquet formatter. [14237]

astropy.io.votable
^^^^^^^^^^^^^^^^^^

- Added a method ``get_infos_by_name`` to make it easier to implement
DALI-compliant protocols [14212]

- Updating the built-in UCD list to upstream 1.5 (which requires a minor
update to the parser) [14554]

astropy.modeling
^^^^^^^^^^^^^^^^

- Enable check for poorly conditioned fits in ``LinearLSQFitter`` for polynomial
models with fixed inputs. [14037]

astropy.nddata
^^^^^^^^^^^^^^

- ``astropy.nddata.NDDataArray`` now has collapsing methods like ``sum``,
``mean``, ``min``, and ``max`` which operate along any axes, and better
support for ``astropy.utils.Masked`` objects. [14175]

astropy.stats
^^^^^^^^^^^^^

- ``vonmisesmle`` has now functioning "weights" and "axis" parameters that work equivalently
to the rest of the functions in the ``circstats`` module (``circmean``, ``rayleightest``, etc.) [14533]

astropy.table
^^^^^^^^^^^^^

- ``Table`` and ``QTable`` can now use the ``|`` and ``|=`` operators for
dictionary-style merge and update. [14187]

astropy.time
^^^^^^^^^^^^

- Add a ``leap_second_strict`` argument to the ``Time.to_datetime()`` method. This
controls the behavior when converting a time within a leap second to the ``datetime``
format and can take the values ``raise`` (the default), ``warn``, or ``silent``. [14606]

astropy.timeseries
^^^^^^^^^^^^^^^^^^

- Adds the ``astropy.timeseries.LombScargleMultiband`` class, which is an
extension of the ``astropy.timeseries.LombScargle`` class. It enables the
generation of periodograms for datasets with measurements taken in more than
one photometric band. [14016]

- Add ``unit_parse_strict`` parameter to the Kepler reader to control the warnings
emitted when reading files. [14294]

astropy.units
^^^^^^^^^^^^^

- Add support for degrees Celsius for FITS. Parsing "Celsius" and "deg C" is now
supported and astropy will output "Celsius" into FITS.

Note that "deg C" is only provided for compatibility with existing FITS files,
as it does not conform to the normal unit standard, where this should be read
as "degree * Coulomb". Indeed, compound units like "deg C kg-1" will still be
parsed as "Coulomb degree per kilogram". [14042]

- Enabled the ``equal_nan`` keyword argument for ``np.array_equal()`` when the
arguments are ``astropy.units.Quantity`` instances. [14135]

- Allow "console" and "unicode" formats for conversion to string of
function units. [14407]

- Add a "fraction" options to all the unit ``format`` classes, which determine
whether, if a unit has bases raised to a negative power, a string
representation should just show the negative powers (``fraction=False``) or
use a fraction, and, in the latter case, whether to use a single-line
representation using a solidus (``fraction='inline'`` or ``fraction=True``)
or, if the format supports it, a multi-line presentation with the numerator
and denominator separated by a horizontal line (``fraction='multiline'``). [14449]

astropy.utils
^^^^^^^^^^^^^

- The ``mean`` method on ``NDDataArray`` now avoids a division by zero
warning when taking the mean of a fully-masked slice (and still
returns ``np.nan``). [14341]

- Ensure we can read the newer ``IERS_B`` files produced by the International
Earth Rotation and Reference Systems Service, and point
``astropy.utils.iers.IERS_B_URL`` to the new location. [14382]


API Changes
-----------

astropy.coordinates
^^^^^^^^^^^^^^^^^^^

- ``get_moon()`` is deprecated and may be removed in a future version of
``astropy``. Calling ``get_moon(...)`` should be replaced with
``get_body("moon", ...)``. [14354]

astropy.io.fits
^^^^^^^^^^^^^^^

- Deprecate the auto-fixing of tile sizes for HCOMPRESS_1 tiled
image compression when the tile size could be changed by +1
to make it acceptable. [14410]

- The ``tile_size=`` argument to ``CompImageHDU`` has been deprecated
as it was confusing that it was required to be in the opposite
order to the data shape (it was in header rather than Numpy order).
Instead, users should make use of the ``tile_shape=`` argument which
is in Numpy shape order. [14428]

astropy.modeling
^^^^^^^^^^^^^^^^

- Deprecate the ``humlicek2`` method for `~astropy.modeling.functional_models.Voigt1D` in favor
of using the ``wofz`` method using the `scipy.special.wofz` implementation of the
Fadeeva function whenever `scipy` is installed. [14013]

- Deprecated ``astropy.modeling.utils.comb()`` function in favor of ``comb()``
from ``math`` standard library. [14038]

- Propagate measurement uncertainties via the ``weights`` keyword argument into the
parameter covariances. [14519]

astropy.units
^^^^^^^^^^^^^

- The conversion of ``astropy.units.Quantity`` to ``bool``
that was deprecated since astropy 3.0 now raises a ``ValueError``.
This affects statements like ``if quantity``.
Use explicit comparisons like ``if quantity.value != 0``
or ``if quantity is not None`` instead. [14124]

- Operations on ``Quantity`` in tables are sped up by only copying ``info`` when
it makes sense (i.e., when the object can still logically be thought of as the
same, such as in unit changes or slicing). ``info`` is no longer copied if a
``Quantity`` is part of an operation. [14253]

- The ``Quantity.nansum`` method has been deprecated. It was always weird that it
was present, since ``ndarray`` does not have a similar method, and the other
``nan*`` functions such as ``nanmean`` did not have a corresponding method.
Use ``np.nansum(quantity)`` instead. [14267]

- The unused ``units.format.Unscaled`` format class has been deprecated. [14417]

- The order in which unit bases are displayed has been changed to match the
order bases are stored in internally, which is by descending power to which
the base is raised, and alphabetical after. This helps avoid monstrosities
like ``beam^-1 Jy`` for ``format='fits'``.

Note that this may affect doctests that use quantities with complicated units. [14439]

astropy.utils
^^^^^^^^^^^^^

- For ``Masked`` instances, the ``where`` argument for any ufunc can now
also be masked (with any masked elements masked in the output as well).
This is not very useful in itself, but avoids problems in conditional
functions (like ``np.add(ma, 1, where=ma>10)``). [14590]

astropy.visualization
^^^^^^^^^^^^^^^^^^^^^

- The pixel attribute of ``astropy.visualization.wcsaxes.frame.Spine`` is deprecated
and will be removed in a future astropy version.
Because it is (in general) not possible to correctly calculate pixel
coordinates before Matplotlib is drawing a figure, instead set the world or data
coordinates of the ``Spine`` using the appropriate setters. [13989]

- Passing a bare number as the ``coord_wrap`` argument to ``CoordinateHelper.set_coord_type`` is deprecated.
Pass a ``Quantity`` with units equivalent to angular degrees instead.

The ``.coord_wrap`` attribute of ``CoordinateHelper`` is now a ``Quantity`` instead of a bare number. [14050]


Bug Fixes
---------

astropy.coordinates
^^^^^^^^^^^^^^^^^^^

- ``Angle.to_string()`` was changed to ensure it matches the behaviour of
``Quantity.to_string()`` in having a space between the value and the unit
for display with non-degree and hourangle units (i.e., the case in which
units are displayed by their name; the sexagesimal case for degrees or
hourangle that uses symbols is not changed). [14379]

astropy.io.ascii
^^^^^^^^^^^^^^^^

- Fix an issue in the ``io.ascii`` QDP format reader to allow lower-case commands in the
table data file. Previously it required all upper case in order to parse QDP files. [14365]

astropy.io.fits
^^^^^^^^^^^^^^^

- Compressing/decompressing a floating point dataset containing NaN values will
no longer read in the whole tile as NaNs.

Fixed segmentation faults that occurred when compressing/decompressing data
with the PLIO_1 algorithm. [14252]

- ``Card`` now uses the default Python representation for floating point
values. [14508]

- ``ImageHDU`` now properly rejects Numpy scalars, avoiding data corruption. [14528]

- Fix issues with double quotes in CONTINUE cards. [14598]

- Fixes an issue where FITS_rec was incorrectly raising a ValueError exception when the heapsize was greater than 2**31
when the Column type was 'Q' instead of 'P'. [14810]

astropy.io.misc
^^^^^^^^^^^^^^^

- Columns with big-endian byte ordering (such as those read in from a FITS table) can now be serialized with Parquet. [14373]

astropy.modeling
^^^^^^^^^^^^^^^^

- Bugfix for using ``getter/setter`` in properties to adjust the internal (computational)
value of a property vs its external proxy value when the values involve units. [14512]

- Fix issue with ``filter_non_finite`` option when fitting with ``weights`` via passing
the ``weights`` through the non-finite-filter alongside the input data. [14695]

- Fixed an issue with Parameter where a getter could be input without a
setter (or vice versa). [14708]

astropy.time
^^^^^^^^^^^^

- Using quantities with units of time for ``Time`` format 'decimalyear' will now
raise an error instead of converting the quantity to days and then
interpreting the value as years. An error is raised instead of attempting to
interpret the unit as years, since the interpretation is ambiguous: in
'decimaltime' years are equal to 365 or 366 days, while for regular time units
the year is defined as 365.25 days. [14566]

astropy.uncertainty
^^^^^^^^^^^^^^^^^^^

- Ensure that ``Distribution`` can be compared with ``==`` and ``!=``
with regular arrays or scalars, and that inplace operations like
``dist[dist<0] *= -1`` work. [14421]

astropy.units
^^^^^^^^^^^^^

- Modified ``astropy.units.Quantity.__array_ufunc__()`` to return ``NotImplemented`` instead of raising a ``ValueError`` if the inputs are incompatible. [13977]

- Modified the behavior of ``numpy.array_equal()`` and ``numpy.array_equiv()`` to
return ``False`` instead of raising an error if their arguments are
``astropy.units.Quantity`` instances with incompatible units. [14163]

- Spaces have been regularized for the ``unicode`` and ``console`` output
formats: no extraneous spaces in front of the unit, and always a space
between a possible scale factor and the unit. [14413]

- Prefixed degrees and arcmin are now typeset without using the symbol in
``latex`` and ``unicode`` formats (i.e., ``mdeg`` instead of ``m°``),
as was already the case for arcsec. [14419]

- Ensure the unit is kept in ``np.median`` even if the result is a scalar ``nan``
(the unit was lost for numpy < 1.22). [14635]

- Ensure that ``Quantity`` with structured dtype can be set using non-structured
``Quantity`` (if units match), and that structured dtype names are inferred
correctly in the creation of ``StructuredUnit``, thus avoiding mismatches
when setting units. [14680]

astropy.utils
^^^^^^^^^^^^^

- When using astropy in environments with sparse file systems (e.g., where the temporary directory and astropy data directory resides in different volumes), ``os.rename`` may fail with ``OSError: [Errno 18] Invalid cross-device link``.
This may affect some clean-up operations executed by the ``data`` module, causing them to fail.
This patch is to catch ``OSError`` with ``errno == EXDEV`` (i.e., Errno 18) when performing these operations and try to use ``shutil.move`` instead to relocate the data. [13730]

- Ensure masks are propagated correctly for ``outer`` methods of ufuncs also if
one of the inputs is not actually masked. [14624]

astropy.visualization
^^^^^^^^^^^^^^^^^^^^^

- The location of a ``astropy.visualization.wcsaxes.frame.Spine`` in a plot is now
correctly calculated when the DPI of a figure changes between a WCSAxes being
created and the figure being drawn. [13989]

- ``CoordinateHelper.set_ticks()`` now accepts ``number=0``. Previously it errored. [14160]

- ``WCSAxes.plot_coord`` and ``plot_scatter`` now work correctly for APE 14 compliant WCSes where the units are not always converted to degrees. [14251]

- Fixed a bug where coordinate overlays did not automatically determine the
longitude wrap angle or the appropriate units. [14326]

astropy.wcs
^^^^^^^^^^^

- Fix bugs with high-level WCS API on ``wcs.WCS`` object when using ``-TAB``
coordinates. [13571]

- Fixed a bug in how WCS handles ``PVi_ja`` header coefficients when ``CTYPE``
has ``-SIP`` suffix and in how code detects TPV distortions. [14295]


Other Changes and Additions
---------------------------

- The minimum supported version of Python is now 3.9, changing from 3.8. [14286]

- The minimum supported version of Numpy is now 1.21. [14349]

- The minimum supported version of matplotlib is now 3.3. [14286, 14321]

- ``astropy`` no longer publishes wheels for i686 architecture. [14517]

- Added a pre-commit configuration for codespell. [13985]

- Removed a large fraction of the bundled CFITSIO code and internally refactored
FITS compression-related code, which has resulted in a speedup when compiling
astropy from source (40% faster in some cases). [14252]

- The CFITSIO library is no longer bundled in full with astropy and
the option to build against an external installation of CFITSIO
has now been removed, so the ASTROPY_USE_SYSTEM_CFITSIO environment
variable will be ignored during building. [14311]

- Updated CDS URL for Sesame look-up as the old URL is deprecated. [14681]

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]

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]

5.2

========================

New Features
------------

astropy.coordinates
^^^^^^^^^^^^^^^^^^^

- Adds new topocentric ITRS frame and direct transforms to and from the observed
frames ``AltAz`` and ``HADec`` with the ability to add or remove refraction
corrections as required. Since these frames are all within the ITRS, there are
no corrections applied other than refraction in the transforms. This makes the
topocentric ITRS frame and these transforms convenient for observers of near
Earth objects where stellar aberration should be omitted. [13398]

- Allow comparing ``SkyCoord`` to frames with data. [13477]

astropy.cosmology
^^^^^^^^^^^^^^^^^

- Cosmology instance can be parsed from or converted to a HTML table using
the new HTML methods in Cosmology's ``to/from_format`` I/O. [13075]

- A new comparison function has been added -- ``cosmology_equal()`` -- that
mirrors its ``numpy`` counterpart but allows for the arguments to be converted
to a ``Cosmology`` and to compare flat cosmologies with their non-flat
equivalents. [13104]

- Cosmology equivalence for flat FLRW cosmologies has been generalized to apply
to all cosmologies using the FlatCosmology mixin. [13261]

- The cosmological redshift unit now has a physical type of ``"redshift"``. [13561]

astropy.io.ascii
^^^^^^^^^^^^^^^^

- Add ability to read and write a fixed width ASCII table that includes additional
header rows specifying any or all of the column dtype, unit, format, and
description. This is available in the ``fixed_width`` and
``fixed_width_two_line`` formats via the new ``header_rows`` keyword argument. [13734]

astropy.io.fits
^^^^^^^^^^^^^^^

- Added support to the ``io.fits`` API for reading and writing file paths of the
form ``~/file.fits`` or ``~<username>/file.fits``, referring to the home
directory of the current user or the specified user, respectively. [13131]

- Added support for opening remote and cloud-hosted FITS files using the
``fsspec`` package, which has been added as an optional dependency. [13238]

astropy.io.votable
^^^^^^^^^^^^^^^^^^

- Added support in ``io.votable`` for reading and writing file paths of the form
``~/file.xml`` or ``~<username>/file.xml``, referring to the home directory of
the current user or the specified user, respectively. [13149]

astropy.modeling
^^^^^^^^^^^^^^^^

- Add option to non-linear fitters which enables automatic
exclusion of non-finite values from the fit data. [13259]

astropy.nddata
^^^^^^^^^^^^^^

- Modified ``Cutout2D`` to allow objects of type ``astropy.io.fits.Section``
to be passed to the ``data`` parameter. [13238]

- Add a PSF image representation to ``astropy.nddata.NDData`` and ``astropy.nddata.CCDData``. [13743]

astropy.table
^^^^^^^^^^^^^

- An Astropy table can now be converted to a scalar NumPy object array. For NumPy
>= 1.20, a list of Astropy tables can be converted to an NumPy object array of
tables. [13469]

astropy.time
^^^^^^^^^^^^

- Added the ``astropy.time.Time.mean()`` method which also enables the ``numpy.mean()`` function to be used on instances of ``astropy.time.Time``. [13508]

- Improve the performance of getting the string representation of a large ``Time``
or ``TimeDelta`` object. This is done via a new ``to_string()`` method that does
the time string format conversion only for the outputted values. Previously the
entire array was formatted in advance. [13555]

astropy.units
^^^^^^^^^^^^^

- It is now possible to use unit format names as string format specifiers for a
``Quantity``, e.g. ``f'{1e12*u.m/u.s:latex_inline}'`` now produces the string
``'$1 \\times 10^{12} \\; \\mathrm{m\\,s^{-1}}$'``. [13050]

- Ensure that the ``argmin`` and ``argmax`` methods of ``Quantity`` support the
``keepdims`` argument when numpy does (numpy version 1.22 and later). [13329]

- ``numpy.lib.recfunctions.merge_arrays()`` is registered with numpy overload for
``Quantity``. [13669]

- Added SI prefixes for quecto ("q", :math:`10^{-30}`), ronto ("r",
:math:`10^{-27}`), ronna ("R", :math:`10^{27}`), and quetta ("Q",
:math:`10^{30}`). [14046]

astropy.utils
^^^^^^^^^^^^^

- Added the ``use_fsspec``, ``fsspec_kwargs``, and ``close_files`` arguments
to ``utils.data.get_readable_fileobj``. [13238]

- Ensure that the ``argmin`` and ``argmax`` methods of ``Masked`` instances
support the ``keepdims`` argument when numpy does (numpy version 1.22 and
later). [13329]

astropy.visualization
^^^^^^^^^^^^^^^^^^^^^

- Add helper functions for WCSAxes instances to draw the instrument beam and a physical scale. [12102]

- Add a ``scatter_coord`` method to the ``wcsaxes`` functionality based on the
existing ``plot_coord`` method but that calls ``matplotlib.pyplot.scatter``. [13562]

- Added a ``sinh`` stretch option to ``simple_norm``. [13746]

- It is now possible to define "tickable" gridlines for the purpose of placing ticks or tick labels in the interior of WCSAxes plots. [13829]


API Changes
-----------

astropy.convolution
^^^^^^^^^^^^^^^^^^^

- Removed deprecated ``MexicanHat1DKernel`` and ``MexicanHat2DKernel``
classes. Please use ``RickerWavelet1DKernel`` and
``RickerWavelet2DKernel`` instead. [13300]

astropy.units
^^^^^^^^^^^^^

- Multiplying a ``LogQuantity`` like ``Magnitude`` with dimensionless physical
units by an array will no longer downcast to ``Quantity``. [12579]

- Quantity normally upcasts integer dtypes to floats, unless the dtype is
specifically provided.
Before this happened when ``dtype=None``; now the default has been changed to
``dtype=numpy.inexact`` and ``dtype=None`` has the same meaning as in `numpy`. [12941]

- In "in-place unit changes" of the form ``quantity <<= new_unit``, the result
will now share memory with the original only if the conversion could be done
through a simple multiplication with a scale factor. Hence, memory will not be
shared if the quantity has integer dtype or is structured, or when the
conversion is through an equivalency. [13638]

- When ``Quantity`` is constructed from a structured array and ``unit`` is
``None``, the default unit is now structured like the input data. [13676]

astropy.utils
^^^^^^^^^^^^^

- ``astropy.utils.misc.suppress`` has been removed, use ``contextlib.suppress``
instead. ``astropy.utils.namedtuple_asdict`` has been removed, instead use
method ``._asdict`` on a ``namedtuple``. ``override__dir__`` has been deprecated
and will be removed in a future version, see the docstring for the better
alternative. [13636]

- ``astropy.utils.misc.possible_filename`` has been removed. [13661]

astropy.visualization
^^^^^^^^^^^^^^^^^^^^^

- Rename number-of-samples keyword ``nsamples`` in ``ZScaleInterval`` to align
with the ``n_samples`` keyword used in all other ``Interval`` classes in
this module. [13810]


Bug Fixes
---------

astropy.convolution
^^^^^^^^^^^^^^^^^^^

- Fixed convolution Kernels to ensure the that returned kernels
are normalized to sum to one (e.g., ``Gaussian1DKernel``,
``Gaussian2DKernel``). Also fixed the Kernel ``truncation`` calculation. [13299]

- Fix import error with setuptools v65.6.0 by replacing
``numpy.ctypeslib.load_library`` with Cython to load the C convolution
extension. [14035]

astropy.coordinates
^^^^^^^^^^^^^^^^^^^

- ``BaseCoordinateFrame.get_frame_attr_names()`` had a misleading name,
because it actually provided a ``dict`` of attribute names and
their default values. It is now deprecated and replaced by ``BaseCoordinateFrame.get_frame_attr_defaults()``.
The fastest way to obtain the attribute names is ``BaseFrame.frame_attributes.keys()``. [13484]

- Fixed bug that caused ``earth_orientation.nutation_matrix()`` to error instead of returning output. [13572]

- Ensure that ``angle.to_string()`` continues to work after pickling,
and that units passed on to ``to_string()`` or the ``Angle``
initializer can be composite units (like ``u.hour**1``), which might
result from preceding calculations. [13933]

astropy.io.fits
^^^^^^^^^^^^^^^

- ``report_diff_values()`` have now two new parameters ``rtol`` and ``atol`` to make the
report consistent with ``numpy.allclose`` results.
This fixes ``FITSDiff`` with multi-dimensional columns. [13465]

astropy.io.votable
^^^^^^^^^^^^^^^^^^

- Fixed two bugs in validator.validator.make_validation_report:
- ProgressBar iterator was not called correctly.
- make_validation_report now handles input string urls correctly. [14102]

astropy.timeseries
^^^^^^^^^^^^^^^^^^

- Fixed a performance regression in ``timeseries.aggregate_downsample``
introduced in Astropy 5.0 / 11266. [13069]

astropy.units
^^^^^^^^^^^^^

- Unit changes of the form ``quantity <<= new_unit`` will now work also if the
quantity is integer. The result will always be float. This means that the result
will not share memory with the original. [13638]

- Ensure dimensionless quantities can be added inplace to regular ndarray. [13913]

astropy.utils
^^^^^^^^^^^^^

- Fixed an incompatibility with latest Python 3.1x versions that kept
``astropy.utils.data.download_file`` from switching to TLS+FTP mode. [14092]

- ``np.quantile`` and ``np.percentile`` can now be used on ``Masked``
arrays and quantities also with ``keepdims=True``. [14113]

astropy.visualization
^^^^^^^^^^^^^^^^^^^^^

- Significantly improve performance of ``ManualInterval`` when both limits
are specified manually. [13898]


Other Changes and Additions
---------------------------

- The deprecated private ``astropy._erfa`` module has been removed. Use
``pyerfa``, which is a dependency of ``astropy`` and can be imported directly
using ``import erfa``. [13317]

- The minimum version required for numpy is now 1.20 and that for scipy 1.5. [13885]

- Updated the bundled CFITSIO library to 4.2.0. [14020]

Update joblib from 1.2.0 to 1.3.2.

Changelog

1.3.2

---------------------------

- Fix a regression in ``joblib.Parallel`` introduced in 1.3.0 where
explicitly setting ``n_jobs=None`` was not interpreted as "unset".
https://github.com/joblib/joblib/pull/1475

- Fix a regression in ``joblib.Parallel`` introduced in 1.3.0 where
``joblib.Parallel`` logging methods exposed from inheritance to
``joblib.Logger`` didn't work because of missing logger
initialization.
https://github.com/joblib/joblib/pull/1494

- Various maintenance updates to the doc, the ci and the test.

https://github.com/joblib/joblib/pull/1481,
https://github.com/joblib/joblib/pull/1476,
https://github.com/joblib/joblib/pull/1492

1.3.1

---------------------------

- Fix compatibility with python 3.7 by vendor loky 3.4.1
which is compatible with this version.
https://github.com/joblib/joblib/pull/1472

1.3.0

---------------------------

- Ensure native byte order for memmap arrays in ``joblib.load``.
https://github.com/joblib/joblib/issues/1353

- Add ability to change default Parallel backend in tests by setting the
``JOBLIB_TESTS_DEFAULT_PARALLEL_BACKEND`` environment variable.
https://github.com/joblib/joblib/pull/1356

- Fix temporary folder creation in `joblib.Parallel` on Linux subsystems on Windows
which do have `/dev/shm` but don't have the `os.statvfs` function
https://github.com/joblib/joblib/issues/1353

- Drop runtime dependency on ``distutils``. ``distutils`` is going away
in Python 3.12 and is deprecated from Python 3.10 onwards. This import
was kept around to avoid breaking scikit-learn, however it's now been
long enough since scikit-learn deployed a fixed (verion 1.1 was released
in May 2022) that it should be safe to remove this.
https://github.com/joblib/joblib/pull/1361

- A warning is raised when a pickling error occurs during caching operations.
In version 1.5, this warning will be turned into an error. For all other
errors, a new warning has been introduced: ``joblib.memory.CacheWarning``.
https://github.com/joblib/joblib/pull/1359

- Avoid (module, name) collisions when caching nested functions. This fix
changes the module name of nested functions, invalidating caches from
previous versions of Joblib.
https://github.com/joblib/joblib/pull/1374

- Add ``cache_validation_callback`` in :meth:`joblib.Memory.cache`, to allow
custom cache invalidation based on the metadata of the function call.
https://github.com/joblib/joblib/pull/1149

- Add a ``return_as`` parameter for ``Parallel``, that enables consuming
results asynchronously.
https://github.com/joblib/joblib/pull/1393,
https://github.com/joblib/joblib/pull/1458

- Improve the behavior of ``joblib`` for ``n_jobs=1``, with simplified
tracebacks and more efficient running time.
https://github.com/joblib/joblib/pull/1393

- Add the ``parallel_config`` context manager to allow for more fine-grained
control over the backend configuration. It should be used in place of the
``parallel_backend`` context manager. In particular, it has the advantage
of not requiring to set a specific backend in the context manager.
https://github.com/joblib/joblib/pull/1392,
https://github.com/joblib/joblib/pull/1457

- Add ``items_limit`` and ``age_limit`` in :meth:`joblib.Memory.reduce_size`
to make it easy to limit the number of items and remove items that have
not been accessed for a long time in the cache.
https://github.com/joblib/joblib/pull/1200

- Deprecate ``bytes_limit`` in ``Memory`` as this is not automatically enforced,
the limit can be directly passed to :meth:`joblib.Memory.reduce_size` which
needs to be called to actually enforce the limit.
https://github.com/joblib/joblib/pull/1447

- Vendor ``loky`` 3.4.0 which includes various fixes.
https://github.com/joblib/joblib/pull/1422

Update jsonschema from 4.16.0 to 4.19.1.

Changelog

4.19.1

=======

* Single label hostnames are now properly considered valid according to the ``hostname`` format.
This is the behavior specified by the relevant RFC (1123).
IDN hostname behavior was already correct.

4.19.0

=======

* Importing the ``Validator`` protocol directly from the package root is deprecated.
Import it from ``jsonschema.protocols.Validator`` instead.
* Automatic retrieval of remote references (which is still deprecated) now properly succeeds even if the retrieved resource does not declare which version of JSON Schema it uses.
Such resources are assumed to be 2020-12 schemas.
This more closely matches the pre-referencing library behavior.

4.18.6

=======

* Set a ``jsonschema`` specific user agent when automatically retrieving remote references (which is deprecated).

4.18.5

=======

* Declare support for Py3.12

4.18.4

=======

* Improve the hashability of wrapped referencing exceptions when they contain hashable data.

4.18.3

=======

* Properly preserve ``applicable_validators`` in extended validators.
Specifically, validators extending early drafts where siblings of ``$ref`` were ignored will properly ignore siblings in the extended validator.

4.18.2

=======

* Fix an additional regression with the deprecated ``jsonschema.RefResolver`` and pointer resolution.

4.18.1

=======

* Fix a regression with ``jsonschema.RefResolver`` based resolution when used in combination with a custom validation dialect (via ``jsonschema.validators.create``).

4.18.0

=======

This release majorly rehauls the way in which JSON Schema reference resolution is configured.
It does so in a way that *should* be backwards compatible, preserving old behavior whilst emitting deprecation warnings.

* ``jsonschema.RefResolver`` is now deprecated in favor of the new `referencing library <https://github.com/python-jsonschema/referencing/>`_.
``referencing`` will begin in beta, but already is more compliant than the existing ``$ref`` support.
This change is a culmination of a meaningful chunk of work to make ``$ref`` resolution more flexible and more correct.
Backwards compatibility *should* be preserved for existing code which uses ``RefResolver``, though doing so is again now deprecated, and all such use cases should be doable using the new APIs.
Please file issues on the ``referencing`` tracker if there is functionality missing from it, or here on the ``jsonschema`` issue tracker if you have issues with existing code not functioning the same, or with figuring out how to change it to use ``referencing``.
In particular, this referencing change includes a change concerning *automatic* retrieval of remote references (retrieving ``http://foo/bar`` automatically within a schema).
This behavior has always been a potential security risk and counter to the recommendations of the JSON Schema specifications; it has survived this long essentially only for backwards compatibility reasons, and now explicitly produces warnings.
The ``referencing`` library itself will *not* automatically retrieve references if you interact directly with it, so the deprecated behavior is only triggered if you fully rely on the default ``$ref`` resolution behavior and also include remote references in your schema, which will still be retrieved during the deprecation period (after which they will become an error).
* Support for Python 3.7 has been dropped, as it is nearing end-of-life.
This should not be a "visible" change in the sense that ``requires-python`` has been updated, so users using 3.7 should still receive ``v4.17.3`` when installing the library.
* On draft 2019-09, ``unevaluatedItems`` now properly does *not* consider items to be evaluated by an ``additionalItems`` schema if ``items`` is missing from the schema, as the specification says in this case that ``additionalItems`` must be completely ignored.
* Fix the ``date`` format checker on Python 3.11 (when format assertion behavior is enabled), where it was too liberal (1076).
* Speed up validation of ``unevaluatedProperties`` (1075).

Deprecations
------------

* ``jsonschema.RefResolver`` -- see above for details on the replacement
* ``jsonschema.RefResolutionError`` -- see above for details on the replacement
* relying on automatic resolution of remote references -- see above for details on the replacement
* importing ``jsonschema.ErrorTree`` -- instead import it via ``jsonschema.exceptions.ErrorTree``
* importing ``jsonschema.FormatError`` -- instead import it via ``jsonschema.exceptions.FormatError``

4.17.3

=======

* Fix instantiating validators with cached refs to boolean schemas
rather than objects (1018).

4.17.2

=======

* Empty strings are not valid relative JSON Pointers (aren't valid under the
RJP format).
* Durations without (trailing) units are not valid durations (aren't
valid under the duration format). This involves changing the dependency
used for validating durations (from ``isoduration`` to ``isodate``).

4.17.1

=======

* The error message when using ``unevaluatedProperties`` with a non-trivial
schema value (i.e. something other than ``false``) has been improved (996).

4.17.0

=======

* The ``check_schema`` method on ``jsonschema.protocols.Validator`` instances
now *enables* format validation by default when run. This can catch some
additional invalid schemas (e.g. containing invalid regular expressions)
where the issue is indeed uncovered by validating against the metaschema
with format validation enabled as an assertion.
* The ``jsonschema`` CLI (along with ``jsonschema.cli`` the module) are now
deprecated. Use ``check-jsonschema`` instead, which can be installed via
``pip install check-jsonschema`` and found
`here <https://github.com/python-jsonschema/check-jsonschema>`_.

4.16.1

=======

* Make ``ErrorTree`` have a more grammatically correct ``repr``.

Update numpy from 1.23.4 to 1.26.0.

Changelog

1.26.0

The NumPy 1.26.0 release is a continuation of the 1.25.x release cycle
with the addition of Python 3.12.0 support. Python 3.12 dropped
distutils, consequently supporting it required finding a replacement for
the setup.py/distutils based build system NumPy was using. We have
chosen to use the Meson build system instead, and this is the first
NumPy release supporting it. This is also the first release that
supports Cython 3.0 in addition to retaining 0.29.X compatibility.
Supporting those two upgrades was a large project, over 100 files have
been touched in this release. The changelog doesn\'t capture the full
extent of the work, special thanks to Ralf Gommers, Sayed Adel, Stéfan
van der Walt, and Matti Picus who did much of the work in the main
development branch.

The highlights of this release are:

-   Python 3.12.0 support.
-   Cython 3.0.0 compatibility.
-   Use of the Meson build system
-   Updated SIMD support

The Python versions supported in this release are 3.9-3.12.

Build system changes

In this release, NumPy has switched to Meson as the build system and
meson-python as the build backend. Installing NumPy or building a wheel
can be done with standard tools like `pip` and `pypa/build`. The
following are supported:

-   Regular installs: `pip install numpy` or (in a cloned repo)
 `pip install .`
-   Building a wheel: `python -m build` (preferred), or `pip wheel .`
-   Editable installs: `pip install -e . --no-build-isolation`
-   Development builds through the custom CLI implemented with
 [spin](https://github.com/scientific-python/spin): `spin build`.

All the regular `pip` and `pypa/build` flags (e.g.,
`--no-build-isolation`) should work as expected.

NumPy-specific build customization

Many of the NumPy-specific ways of customizing builds have changed. The
`NPY_*` environment variables which control BLAS/LAPACK, SIMD,
threading, and other such options are no longer supported, nor is a
`site.cfg` file to select BLAS and LAPACK. Instead, there are
command-line flags that can be passed to the build via `pip`/`build`\'s
config-settings interface. These flags are all listed in the
`meson_options.txt` file in the root of the repo. Detailed documented
will be available before the final 1.26.0 release; for now please see
[the SciPy \"building from source\"docs](http://scipy.github.io/devdocs/building/index.html) since most
build customization works in an almost identical way in SciPy as it does
in NumPy.

Build dependencies

While the runtime dependencies of NumPy have not changed, the build
dependencies have. Because we temporarily vendor Meson and meson-python,
there are several new dependencies - please see the `[build-system]`
section of `pyproject.toml` for details.

Troubleshooting

This build system change is quite large. In case of unexpected issues,
it is still possible to use a `setup.py`-based build as a temporary
workaround (on Python 3.9-3.11, not 3.12), by copying
`pyproject.toml.setuppy` to `pyproject.toml`. However, please open an
issue with details on the NumPy issue tracker. We aim to phase out
`setup.py` builds as soon as possible, and therefore would like to see
all potential blockers surfaced early on in the 1.26.0 release cycle.
