==========================
Bug Fixes
---------
astropy.coordinates
^^^^^^^^^^^^^^^^^^^
- Ecliptic frame classes now support attributes ``v_x``, ``v_y``, ``v_z`` when
using with a Cartesian representation. [6569]
- Added a nicer error message when accidentally calling ``frame.representation``
instead of ``frame.data`` in the context of methods that use ``._apply()``.
[6561]
- Creating a new ``SkyCoord`` from a list of multiple ``SkyCoord`` objects now
yield the correct type of frame, and works at all for non-equatorial frames.
[6612]
- Improved accuracy of velocity calculation in ``EarthLocation.get_gcrs_posvel``.
[6699]
- Improved accuracy of radial velocity corrections in
``SkyCoord.radial_velocity_correction. [6861]
- The precision of ecliptic frames is now much better, after removing the
nutation from the rotation and fixing the computation of the position of the
Sun. [6508]
astropy.extern
^^^^^^^^^^^^^^
- Version 0.2.1 of ``pytest-astropy`` is included as an external package.
[6918]
astropy.io.fits
^^^^^^^^^^^^^^^
- Fix writing the result of ``fitsdiff`` to file with ``--output-file``. [6621]
- Fix a minor bug where ``FITS_rec`` instances can not be indexed with tuples
and other sequences that end up with a scalar. [6955, 6966]
astropy.io.misc
^^^^^^^^^^^^^^^
- Fix ``ImportError`` when ``hdf5`` is imported first in a fresh Python
interpreter in Python 3. [6604, 6610]
astropy.nddata
^^^^^^^^^^^^^^
- Suppress errors during WCS creation in CCDData.read(). [6500]
- Fixed a problem with ``CCDData.read`` when the extension wasn't given and the
primary HDU contained no ``data`` but another HDU did. In that case the header
were not correctly combined. [6489]
astropy.stats
^^^^^^^^^^^^^
- Fixed an issue where the biweight statistics functions would
sometimes cause runtime underflow/overflow errors for float32 input
arrays. [6905]
astropy.table
^^^^^^^^^^^^^
- Fixed a problem when printing a table when a column is deleted and
garbage-collected, and the format function caching mechanism happens
to reuse the same cache key. [6714]
- Fixed a problem when comparing a unicode masked column (on left side) to
a bytes masked column (on right side). [6899]
- Fixed a problem in comparing masked columns in bytes and unicode when the
unicode had masked entries. [6899]
astropy.tests
^^^^^^^^^^^^^
- Fixed a bug that causes tests for rst files to not be run on certain
platforms. [6555, 6608]
- Fixed a bug that caused the doctestplus plugin to not work nicely with the
hypothesis package. [6605, 6609]
- Fixed a bug that meant that the data.astropy.org mirror could not be used when
using --remote-data=astropy. [6724]
- Support compatibility with new ``pytest-astropy`` plugins. [6918]
- When testing, astropy (or the package being tested) is now installed to
a temporary directory instead of copying the build. This allows
entry points to work correctly. [6890]
astropy.time
^^^^^^^^^^^^
- Initialization of Time instances now is consistent for all formats to
ensure that ``-0.5 <= jd2 < 0.5``. [6653]
astropy.units
^^^^^^^^^^^^^
- Ensure that ``Quantity`` slices can be set with objects that have a ``unit``
attribute (such as ``Column``). [6123]
astropy.utils
^^^^^^^^^^^^^
- ``download_files_in_parallel`` now respects the given ``timeout`` value.
[6658]
- Fixed bugs in remote data handling and also in IERS unit test related to path
URL, and URI normalization on Windows. [6651]
- Fixed a bug that caused ``get_pkg_data_fileobj`` to not work correctly when
used with non-local data from inside packages. [6724]
- Make sure ``get_pkg_data_fileobj`` fails if the URL can not be read, and
correctly falls back on the mirror if necessary. [6767]
- Fix the ``finddiff`` option in ``find_current_module`` to properly deal
with submodules. [6767]
- Fixed ``pyreadline`` import in ``utils.console.isatty`` for older IPython
versions on Windows. [6800]
astropy.visualization
^^^^^^^^^^^^^^^^^^^^^
- Fixed the vertical orientation of the ``fits2bitmap`` output bitmap
image to match that of the FITS image. [6844, 6969]
- Added a workaround for a bug in matplotlib so that the ``fits2bitmap``
script generates the correct output file type. [6969]
Other Changes and Additions
---------------------------
- No longer require LaTeX to build the documentation locally and
use mathjax instead. [6701]
- Ensured that all tests use the Astropy data mirror if needed. [6767]
