Drizzlepac

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

- Changed the color scheme of the ``hist2d`` plots to ``viridis``. [167]

- Refactored test suite

- ``sdist`` now packages C extension source code

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

- Replace ``pyregion`` with ``stregion``

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

- Updated links in the documentation to point to latest
``drizzlepac`` website and online API documentation.

- Code cleanup.

- Updated C code to be more compatible with latest numpy releases in order
to reduce numerous compile warnings.

- Updated documentation to eliminate (at this moment) all sphinx documentation
generation warnings.

- Moved ``'release_notes.rst'`` to ``'CHANGELOG.rst'`` in the top-level
directory.

- Improved setup to allow documentation build. See
`drizzlepac PR 142 <https://github.com/spacetelescope/drizzlepac/pull/142>`_
and `Issue 129 <https://github.com/spacetelescope/drizzlepac/issues/129>`_
for more details.

- Fixed a bug in a print statement in the create median step due to which
background values for input images used in this step were not printed.

- Fixed a bug due to which ``TweakReg`` may have effectively ignored
``verbose`` setting.

- Fixed a bug in ``drizzlepac.util.WithLogging`` due to which ``astrodrizzle``
would throw an error trying when to raise another error.
See `Issue 157 <https://github.com/spacetelescope/drizzlepac/issues/157>`_
for more details.

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

- Fixed a bug in ``TweakReg`` introduced in ``v2.2.0`` due to which, when
``TweakReg`` is run from the interpreter, the code may crash when trying to
interpret input files.

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

- Fixed problems with processing WFPC2 data provided by the archive. User will
need to make sure they run ``updatewcs`` on all input WFPC2 data before
combining them with ``astrodrizzle``.

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

- Implemented a major refactor of the project directory structure. Building no
longer requires ``d2to1`` or ``stsci.distutils``. Drizzlepac's release
information (i.e. version, build date, etc) is now handled by ``relic``.
See https://github.com/spacetelescope/relic

- Added basic support for compiling Drizzlepac's C extensions under Windows.

- Documentation is now generated during the build process. This ensures the
end-user always has access to documentation that applies to the version of
``drizzlepac`` being used.

- Swapped the effect of setting ``configobj`` to `None` or ``'defaults'`` in
``AstroDrizzle`` and ``TweakReg``. When calling one of these tasks with
``configobj`` parameter set to `None`, values for the
not-explicitly-specified parameters should be set to the default values
for the task. When ``configobj`` is set to ``'defaults'``
not-explicitly-specified parameters will be loaded from the
``~/.teal/astrodrizzle.cfg`` or ``~/.teal/tweakreg.cfg`` files that store
latest used settings (or from matching configuration files in the current
directory). See https://github.com/spacetelescope/drizzlepac/pull/115
for more details.
