API Changes

astropy.wcs

- Integer indices beyond the size of an axis are now rejected when slicing a
  ``SlicedLowLevelWCS`` with a known shape, as for Numpy arrays. In addition,
  ``simplify_basic_index`` now accepts `None` entries in ``shape`` for dimensions
  whose size is not known, in which case the index for that dimension is
  returned unchanged, except that a negative integer or slice start raises a
  ``ValueError``.

Bug Fixes

astropy.coordinates

- Fixed ``BaseRepresentation.represent_as`` mutating a source representation when
  converting attached differentials to another class, which could cause a repeated
  ``SkyCoord.apply_space_motion`` call after displaying the coordinate to fail.

- Fixed two rounding errors in ``Angle.to_string``. The seconds were carried into
  the next minute half a unit too early, so that, e.g.,
  ``Angle("1d2m59.49999s").to_string(precision=0)`` gave ``1d03m00s`` instead of
  ``1d02m59s``. And with ``fields=1`` the seconds were rounded into the minutes
  before the minutes were rounded into the degrees, rounding twice, so that, e.g.,
  ``Angle("285d29m41.76s").to_string(fields=1)`` gave ``286d`` instead of ``285d``.

astropy.io.ascii

- The ``latex`` and ``aastex`` readers no longer treat an ampersand inside a
  braced ``{...}`` group or an escaped ``\&`` as a column separator, so tables
  with a reference column such as ``\cite{2013A&A...558A..33A}`` now read
  correctly.

astropy.io.fits

- Fixed ``fitsinfo`` and ``fitsheader`` crashing with a traceback when run on
  an LZW-compressed ``.Z`` file while the optional ``uncompresspy`` dependency
  is not installed. The scripts now broadly catch exceptions and report a
  clean error message, matching the behaviour of the ``fitscheck`` and
  ``fitsdiff`` scripts.

- The ``ZQUANTIZ`` keyword is no longer written to the header of compressed
  image HDUs when no quantization is applied (i.e., for integer data, or
  floating point data compressed with ``quantize_method=NO_DITHER``). A few
  FITS readers, including DS9 and ``fv``, currently treat the mere presence
  of ``ZQUANTIZ`` as an indication that the data are quantized, regardless
  of its value, and cannot read the files.  Omitting the keyword when it is
  not needed is fully standards-compliant, as a missing ``ZQUANTIZ`` is
  already interpreted as ``NO_DITHER``.

astropy.io.misc

- Fixed the ``format="ecsv"`` ECSV reader to correctly read an empty table that has
  no columns. Previously this was raising an ``InconsistentTableError``. The legacy
  ``format="ascii.ecsv"`` ECSV reader was already handling this case correctly.

astropy.io.votable

- Prevent overflow on 32-bit systems and WebAssembly when reading binary VOTables by
  changing the ambiguous types of ``null_value`` to fixed-width equivalents (e.g., from
  ``long`` to ``int64_t``).

- Passing an integer column index equal to the number of fields in ``columns`` now raises the intended ``ValueError``.

astropy.modeling

- Fixed the step size used by the non-linear least-squares fitters
  (``LevMarLSQFitter``, ``TRFLSQFitter``, ``DogBoxLSQFitter``, and
  ``LMLSQFitter``) to estimate the Jacobian by finite differences when
  a model has no ``fit_deriv`` or when ``estimate_jacobian=True``. The
  relative step was the fourth root of the machine precision (about
  1.2e-4) instead of the square root (about 1.5e-8), so fits could stop
  short of the minimum for parameters with large values, such as a
  position far from the coordinate origin.

astropy.nddata

- Fix ``block_replicate`` with ``conserve_sum=True`` inadvertently promoting ``float16``, ``float32``, and ``complex64`` input arrays to wider dtypes.

astropy.stats

- Fixed a bug where ``astropy.stats.histogram()`` raised a ``ValueError`` when both ``range`` and ``weights`` were provided with a scalar number of bins. For scalar bin counts, 
``calculate_bin_edges()`` now delegates range filtering directly to ``numpy.histogram_bin_edges()``, avoiding an array shape mismatch between data and weights while reserving manual range filtering 
for Astropy's string-based bin width estimators.

- Fixed an out-of-bounds memory read in the C implementation of ``sigma_clip`` (used when ``axis`` is given with ``cenfunc``/``stdfunc`` set to their string values) that occurred when a clipping 
iteration rejected all remaining values. This could cause a crash or return incorrect (unmasked) results; the fast path now returns the same result as the pure-python implementation in this case.

astropy.table

- Fixed issue with table groups for zero-length tables in ``astropy.table``. Previously
  operations like ``len(tbl.group_by("a").groups)`` or ``len(tbl.groups)`` would fail or
  give inconsistent results if the table ``tbl`` had no rows.

- Fixed an issue when deep-copying a ``Table`` where the copied columns lost their link to
  the new parent table. This led to problems in ``rename_columns`` and ``info.name``
  assignment. Other potential problems included table-aware unit conversion/replacement in
  QTable, grouped-column linkage to table group metadata, and synchronized pprint
  include/exclude name bookkeeping on rename or delete.

- Fixed an issue where ``vstack`` was returning the input table itself when given
  a single table. It now returns a copy of that table, consistent with the documented
  behavior of always returning a new table.

- Fixed ``Table.to_pandas()`` and ``Table.to_df()`` silently corrupting masked
  integer columns whose values are too large to be represented exactly as a
  float64, e.g. Gaia source ids. The nullable integer column is now built
  directly from the integer data and the mask instead of via a float64
  intermediate. Only the pandas backend was affected; polars and pyarrow already
  round-tripped these values exactly.

- Fixed a bug where a numpy function used on a ``MaskedColumn`` produced output
  with a different dtype than the input (e.g., ``np.strings.find``), which would
  later lead to a ``TypeError`` from a stale ``fill_value`` dtype. Now, when
  the fill_value is no longer valid for the output dtype, fall back to the
  default fill_value for that dtype instead of propagating the stale value.
  This can now raise a castings warnings following standard numpy casting rules.

- Fixed a memory leak when repeatedly slicing a table that has an index on a
  ``MaskedColumn``, e.g. ``t[t["idx"] == value]``. Each such access used to make a
  deep copy of the whole index that was never freed, and any slice of a slice of an
  indexed ``MaskedColumn`` (or a derived array such as a comparison result) silently
  shared the original column's index.

astropy.time

- Fixed ``Time.__setitem__`` silently dropping the mask when a masked ``Time`` was
  assigned into an unmasked one. As a result, ``vstack`` no longer loses the mask
  on ``Time`` mixin columns.

- Fixed a bug where ``Time.insert`` (and therefore ``Table.add_row`` for a ``Time``
  column) silently dropped the mask, exposing values that should have stayed
  masked.  This affected both the mask of the original object and the mask of the
  inserted values.

- Fixed ``Time.strftime`` and the string formats (``iso``, ``isot``, ``fits``,
  ``yday``) returning values at the wrong index for a ``Time`` array that is not
  C-contiguous in memory, for example after ``.T`` or ``np.moveaxis``, or when
  built from a Fortran-ordered array.

astropy.utils

- Fixed an issue where, in a multi-threaded context, astropy's logger could race with
  imports, leading to an exception being raised.

- Flipped ``astropy.utils.data.conf.dataurl`` and ``astropy.utils.data.conf.dataurl_mirror`` to reduce URL redirect, in hope to reduce service denial.

- Fix XML regex bugs and improve speed of token check.

astropy.visualization

- Fixed a number of bugs in WCSAxes:

  * Setting the number of ticks to zero no longer crashes drawing, minor
    ticks, or the mouseover coordinate display.
  * Contour-type grids no longer crash for a longitude coordinate with fewer
    than two ticks or for a coordinate sliced out of the plot, and no longer
    draw a spurious gridline along the longitude wrap for a single tick.
  * Drawing a gridline sampled with fewer than three points no longer crashes.
  * Transforming empty coordinate arrays no longer crashes for 1-d WCS and
    now returns correctly shaped arrays.
  * Simplifying tick labels no longer crashes when one label is a prefix of
    an adjacent one.
  * Tick values for longitude coordinates in non-degree units are no longer
    corrupted when a tick intersects a spine more than once.
  * ``%``-style tick formats now use the format unit instead of the
    coordinate's native unit.
  * Invalid tick format strings now raise a ``ValueError`` instead of being
    silently accepted with reduced precision.
  * ``get_coords_overlay`` no longer ignores a supplied ``coord_meta`` when
    passed a WCS.
  * The default conversion of right ascension format units to hourangle no
    longer depends on unit object identity.
  * ``custom_ucd_coord_meta_mapping`` no longer applies earlier keys when a
    later key conflicts, and now raises for keys specified more than once.
  * The cursor coordinate display no longer breaks after ``reset_wcs`` and
    now preserves the pixel display mode.
  * Automatically-placed coordinates are now hidden instead of crashing when
    no spine assignment is consistent with fixed tick positions.
  * Formatting a coordinate for the mouseover display no longer crashes for
    a degenerate (zero-size) coordinate range.

- Fixed a bug which caused WCSAxes to fail when having to transform coordinate frames
  in the case where APE 14 WCS implementations used frame names or non-instantiated
  classes in ``world_axis_object_classes`` (which is valid).

- Fixed ``WCSAxes.get_transform`` dropping the unit conversion when given a coordinate frame that matches the frame of the axes' WCS.

astropy.wcs

- Fixed a bug that could cause a segmentation fault when using a WCS object with
  ``preserve_units=True`` and where units has already been defined and the WCS
  had been ``set()`` but the scaling factors were found to be 1, and when cdelt or
  crval were subsequently set.

- Fix ``WCS.to_header()`` for cases where ``preserve_units=True``, units were set programmatically, and ``WCS.set()`` was not called.

- Fixed a race condition in which concurrent failing transforms on the same
  ``WCS`` object could allocate the internal error buffer twice, leaking one
  allocation. The buffer is now allocated once when the object is created.

- Fixed a race condition in which deepcopying a ``WCS`` object while another
  thread used it could raise ``RuntimeError: dictionary changed size during
  iteration``.

- Fixed slicing of WCS objects with negative values, which were previously used
  as literal pixel offsets rather than being interpreted relative to the end of
  the axis as for Numpy arrays. Negative values are now resolved when the shape of
  the data is known, and a negative integer or slice start now raises a
  ``ValueError`` when it is not. Also fixed nested ``SlicedLowLevelWCS`` objects
  rejecting slices with an explicit step of 1.

- Fix bug in ``astropy.wcs.utils.fit_wcs_from_points`` so the ``proj_point`` will be transformed to the ``world_coords`` coordinate frame.
