astropy 2.0.4 -> 3.0

3.0

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

New Features

astropy.config
^^^^^^^^^^^^^^

astropy.constants
^^^^^^^^^^^^^^^^^

• New context manager set_enabled_constants to temporarily use an older
  version. [7008]

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

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

• The Distance object now accepts parallax as a keyword in the
  initializer, and supports retrieving a parallax (as an Angle) via
  the .parallax attributes. [6855]

• The coordinate frame classes (subclasses of BaseCoordinateFrame) now
  always have .velocity, .proper_motion, and .radial_velocity
  properties that provide shorthands to the full-space Cartesian velocity as
  a CartesianDifferential, the 2D proper motion as a Quantity, and the
  radial or line-of-sight velocity as a Quantity. [6869]

• SkyCoord objects now support storing and tranforming differentials - i.e.,
  both radial velocities and proper motions. [6944]

• All frame classes now automatically get sensible representation mappings for
  velocity components. For example, d_x, d_y, d_z are all
  automatically mapped to frame component namse v_x, v_y, v_z.
  [6856]

• SkyCoord objects now support updating the position of a source given its
  space motion and a new time or time difference. [6872]

• The frame classes now accept a representation class or differential class, or
  string names for either, through the keyword arguments representation_type
  and differential_type instead of representation and
  differential_cls. [6873]

• The frame classes (and SkyCoord) now give more useful error messages when
  incorrect attribute names are given. Instead of using the representation
  attribute names, they use the frame attribute names. [7106]

• EarthLocation now has a method to compute the gravitational redshift due
  due to solar system bodies. [6861, 6935]

• EarthLocation now has a get_gcrs convenience method to get the
  location in GCRS coordinates. [6861, 6935]

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

astropy.extern
^^^^^^^^^^^^^^

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

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

• Expanded the FITS Column interface to accept attributes pertaining to the FITS
  World Coordinate System, which includes spatial(celestial) and time coordinates. [6359]

• Added ver attribute to set the EXTVER header keyword to ImageHDU
  and TableHDU. [6454]

• The performance for reading FITS tables has been significantly improved,
  in particular for cases where the tables contain one or more string columns
  and when done through Table.read. [6821]

• The performance for writing tables from Table.write has now been
  significantly improved for tables containing one or more string columns. [6920]

• The Table.read now supports a memmap= keyword argument to control
  whether or not to use memory mapping when reading the table. [6821]

• When reading FITS tables with fits.open, a new keyword argument
  character_as_bytes can be passed - when set to True, character columns
  are returned as Numpy byte arrays (Numpy type S) while when set to False,
  the same columns are decoded to Unicode strings (Numpy type U) which uses more
  memory. [6821]

• The table_to_hdu function and the BinTableHDU.from_columns and
  FITS_rec.from_columns methods now include a character_as_bytes
  keyword argument - if set to True, then when string columns are accessed,
  byte columns will be returned, which can provide significantly improved
  performance. [6920]

• Added support for writing and reading back a table which has "mixin columns"
  such as SkyCoord or EarthLocation with no loss of information. [6912]

• Enable tab-completion for FITS_rec column names and Header keywords
  with IPython 5 and later. [7071]

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

• When writing to HDF5 files, the serialized metadata are now saved in a new
  dataset, instead of the HDF5 dataset attributes. This allows for metadata of
  any dimensions. [6304]

• Added support in HDF5 for writing and reading back a table which has "mixin
  columns" such as SkyCoord or EarthLocation with no loss of
  information. [7007]

• Add implementations of astropy-specific ASDF tag types. [6790]

• Add ASDF tag and schema for ICRSCoord. [6904]

astropy.io.registry
^^^^^^^^^^^^^^^^^^^

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

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

• Add unit support for tabular models. [6529]

• A deepcopy() method was added to models. [6515]

• Added units support to AffineTransformation. [6853]

• Added is_separable function to modeling to test the
  separability of a model. [6746]

• Added Model.separable property. It returns a boolean value or
  None if not set. [6746]

• Support masked array values in LinearLSQFitter (instead of silently
  ignorning the mask). [6927]

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

astropy.samp
^^^^^^^^^^^^

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

• Added false alarm probability computation to astropy.stats.LombScargle
  [6488]

• Implemented Kuiper functions in astropy.stats [3724, 6565]

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

• Added support for reading and writing astropy.time.Time Table columns
  to and from FITS tables, to the extent supported by the FITS standard. [6176]

• Improved exception handling and error messages when column format
  attribute is incorrect for the column type. [6385]

• Allow to pass htmldict option to the jsviewer writer. [6551]

• Added new table operation astropy.table.setdiff that returns the set
  difference of table rows for two tables. [6443]

• Added support for reading time columns in FITS compliant binary tables
  as astropy.time.Time Table columns. [6442]

• Allowed to remove table rows through the __delitem__ method. [5839]

• Added a new showtable command-line script to view binary or ASCII table
  files. [6859]

• Added new table property astropy.table.Table.loc_indices that returns the
  location of rows by indexes. [6831]

• Allow updating of table by indices through the property astropy.table.Table.loc. [6831]

• Enable tab-completion for column names with IPython 5 and later. [7071]
• Allow getting and setting a table Row using multiple column names. [7107]

astropy.tests
^^^^^^^^^^^^^

• Split pytest plugins into separate modules. Move remotedata, openfiles,
  doctestplus plugins to standalone repositories. [6384, 6606]

• 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]

• The tests_require setting in setup.py now works properly when running
  'python setup.py test'. [6892]

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

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

• Deprecated conversion of quantities to truth values. Currently, the expression
  bool(0 * u.dimensionless_unscaled) evaluates to True. In the future,
  attempting to convert a Quantity to a bool will raise ValueError.
  [6580, 6590]

• Modify the brightness_temperature equivalency to provide a surface
  brightness equivalency instead of the awkward assumed-per-beam equivalency
  that previously existed [5173, 6663]

• Support was added for a number of scipy.special functions. [6852]

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

• The astropy.utils.console.ProgressBar.map class method now supports the
  ipython_widget option. You can now pass it both multiprocess=True and
  ipython_widget=True to get both multiprocess speedup and a progress bar
  widget in an IPython Notebook. [6368]

• The astropy.utils.compat.funcsigs module has now been deprecated. Use the
  Python 'inspect' module directly instead. [6598]

• The astropy.utils.compat.futures module has now been deprecated. Use the
  Python 'concurrent.futures' module directly instead. [6598]

• JsonCustomEncoder is expanded to handle Quantity and UnitBase.
  [5471]

• Added a dcip_xy method to IERS that interpolates along the dX_2000A and
  dY_2000A columns of the IERS table. Hence, the data for the CIP offsets is
  now available for use in coordinate frame conversion. [5837]

• The functions matmul, broadcast_arrays, broadcast_to of the
  astropy.utils.compat.numpy module have been deprecated. Use the
  NumPy functions directly. [6691]

• The astropy.utils.console.ProgressBar.map class method now returns
  results in sequential order. Previously, if you set multiprocess=True,
  then the results could arrive in any arbitrary order, which could be a nasty
  shock. Although the function will still be evaluated on the items in
  arbitrary order, the return values will arrive in the same order in which the
  input items were provided. The method is now a thin wrapper around
  astropy.utils.console.ProgressBar.map_unordered, which preserves the old
  behavior. [6439]

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

• Enable Matplotlib's subtraction shorthand syntax for composing and
  inverting trasformations for the WCSWorld2PixelTransform and
  WCSPixel2WorldTransform classes by setting has_inverse to True.
  In order to implement a unit test, also implement the equality comparison
  operator for both classes. [6531]

• Added automatic hiding of axes labels when no tick labels are drawn on that
  axis. This parameter can be configured with
  WCSAxes.coords[*].set_axislabel_visibility_rule so that labels are automatically
  hidden when no ticks are drawn or always shown. [6774]

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

• Added a new function celestial_frame_to_wcs to convert from
  coordinate frames to WCS (the opposite of what wcs_to_celestial_frame
  currently does. [6481]

• wcslib was updated to v 5.18. [7066]

API Changes

astropy.config
^^^^^^^^^^^^^^

astropy.constants
^^^^^^^^^^^^^^^^^

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

• Gaussian2DKernel now accepts x_stddev in place of stddev with
  an option for y_stddev, if different. It also accepts theta like
  Gaussian2D model. [3605, 6748]

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

• Deprecated recommended_units for representations. These were used to
  ensure that any angle was presented in degrees in sky coordinates and
  frames. This is more logically done in the frame itself. [6858]

• As noted above, the frame class attributes representation and
  differential_cls are being replaced by representation_type and
  differential_type. In the next version, using representation will raise
  a deprecation warning. [6873]

• Coordinate frame classes now can't be added to the frame transform graph if
  they have frame attribute names that conflict with any component names. This
  is so SkyCoord can uniquely identify and distinguish frame attributes from
  frame components. [6871]

• Slicing and reshaping of SkyCoord and coordinate frames no longer passes
  the new object through __init__, but directly sets atttributes on a new
  instance. This speeds up those methods by an order of magnitude, but means
  that any customization done in __init__ is by-passed. [6941]

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

astropy.extern
^^^^^^^^^^^^^^

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

• Allow ECSV files to be auto-identified by Table.read or Table.write based
  on the .ecsv file name suffix. In this case it is not required to provide the
  format keyword. [6552]

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

• Automatically detect and handle compression in FITS files that are opened by
  passing a file handle to fits.open [6373]

• Remove the nonstandard checksum option. [6571]

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

• When writing to HDF5 files, the serialized metadata are now saved in a new
  dataset instead of the HDF5 dataset attributes. This allows for metadata of
  any dimensions. [6304]

• Deprecated the usecPickle kwarg of fnunpickle and fnpickle as
  it was needed only for Python2 usage. [6655]

astropy.io.registry
^^^^^^^^^^^^^^^^^^^

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

• Add handling of tree.Group elements to tree.Resource. Unified I/O
  or conversion to astropy tables is not affected. [6262]

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

• Removed deprecated GaussianAbsorption1D model.
  Use Const1D - Gaussian1D instead. [6542]

• Removed the registry from modeling. [6706]

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

astropy.samp
^^^^^^^^^^^^

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

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

• When setting the column format attribute the value is now immediately
  validated. Previously one could set to any value and it was only checked
  when actually formatting the column. [6385]

• Deprecated the python3_only kwarg of the
  convert_bytestring_to_unicode and convert_unicode_to_bytestring
  methods it was needed only for Python2 usage. [6655]

• When reading in FITS tables with Table.read, string columns are now
  represented using Numpy byte (dtype S) arrays rather than Numpy
  unicode arrays (dtype U). The Column class then ensures the
  bytes are automatically converted to string as needed. [6821]

• When getting a table row using multiple column names, if one of the
  names is not a valid column name then a KeyError exception is
  now raised (previously ValueError). When setting a table row,
  if the right hand side is not a sequence with the correct length
  then a ValueError is now raised (previously in certain cases
  a TypeError was raised). [7107]

astropy.tests
^^^^^^^^^^^^^

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

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

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

• download_files_in_parallel now always uses cache=True to make the
  function work on Windows. [6671]

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

• The Astropy matplotlib plot style has been deprecated. It will continue to
  work in future but is no longer documented. [6991]

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

Bug Fixes

astropy.config
^^^^^^^^^^^^^^

astropy.constants
^^^^^^^^^^^^^^^^^

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

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

• Frame objects now use the default differential even if the representation is
  explicitly provided as long as the representation provided is the same type as
  the default representation. [6944]

• Coordinate frame classes now raise an error when they are added to the frame
  transform graph if they have frame attribute names that conflict with any
  component names. [6871]

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

astropy.extern
^^^^^^^^^^^^^^

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

• Added support for reading very large tables in chunks to reduce memory
  usage. [6458]

• Strip leading/trailing white-space from latex lines to avoid issues when
  matching \begin{tabular} statements. This is done by introducing a new
  LatexInputter class to override the BaseInputter. [6311]

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

• Properly handle opening of FITS files from http.client.HTTPResponse (i.e.
  it now works correctly when passing the results of urllib.request.urlopen
  to fits.open). [6378]

• Fix the fitscheck script for updating invalid checksums, or removing
  checksums. [6571]

• Fixed potential problems with the compression module [6732]

• Always use the 'D' format for floating point values in ascii tables. [6938]

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

astropy.io.registry
^^^^^^^^^^^^^^^^^^^

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

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

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

astropy.samp
^^^^^^^^^^^^

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

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

• Fix getting a table row when using multiple column names (for example
  t[3]['a', 'b', 'c']). Also fix a problem when setting an entire row:
  if setting one of the right-hand side values failed this could result in
  a partial update of the referenced parent table before the exception is
  raised. [7107]

astropy.tests
^^^^^^^^^^^^^

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

• Initialization of Time instances with bytes or arrays with dtype S
  will now automatically attempt to decode as ASCII. This ensures Column
  instances with ASCII strings stored with dtype S can be used.
  [6823, 6903]

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

• Fixed a bug that caused PLY files to not be generated correctly in Python 3.
  [7174]

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

• The deprecated decorator applied to a class will now modify the class
  itself, rather than to create a class that just looks and behave like the
  original. This is needed so that the Python 3 super without arguments
  works for decorated classes. [6615]

• Fixed HomogeneousList when setting one item or a slice. [6773]

• Also check the type when creating a new instance of
  HomogeneousList. [6773]

• Make HomogeneousList work with iterators and generators when creating the
  instance, extending it, or using when setting a slice. [6773]

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

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

• Matplotlib axes have the axisbelow property to control the z-order of
  ticks, tick labels, and grid lines. WCSAxes will now respect this property.
  This is useful for drawing scale bars or inset boxes, which should have a
  z-order that places them above all ticks and gridlines. [7098]

astropy.vo

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

hypothesis 3.44.26 -> 3.45.2

3.45.2

---

This release makes our docstring style more consistent, thanks to
:pypi:flake8-docstrings. There are no user-visible changes.

---

3.45.1

---

This fixes an indentation issue in docstrings for
:func:~hypothesis.strategies.datetimes, :func:~hypothesis.strategies.dates,
:func:~hypothesis.strategies.times, and
:func:~hypothesis.strategies.timedeltas.

---

3.45.0

---

This release fixes :func:~hypothesis.strategies.builds so that target
can be used as a keyword argument for passing values to the target. The target
itself can still be specified as a keyword argument, but that behavior is now
deprecated. The target should be provided as the first positional argument.

---

That's it for now!
