================
New Features
------------
- Added flux/surface brightness translation and surface brightness
unit conversion in Cubeviz and Specviz. [2781]
- Plugin tray is now open by default. [2892]
- New "About" plugin to show Jdaviz version info. [2886]
- Descriptions are shown in the color mode dropdown for image layers to help describe the use-cases
for ``Colormap`` vs ``Color``. [2894]
- The colormap menu for image layers now shows in-line previews of the colormaps. [2900]
Cubeviz
^^^^^^^
- Automatic spectral extraction now goes through the logic of the spectral extraction plugin for
self-consistency. This results in several breaking changes to data-labels and ``get_data``
(the extracted spectra are now given dedicated data-labels instead of referring to them by
the label of the flux cube) as well as to several plugins: model fitting, gaussian smooth,
line analysis, and moment maps. [2827]
- Background subtraction support within Spectral Extraction. [2859]

API Changes
-----------
- The ``Monochromatic`` option for ``color_mode`` in plot options is now renamed to ``Color``.
``Monochromatic`` will continue to work with a deprecation warning, but may be removed in a
future release. [2894]
Cubeviz
^^^^^^^
- ``get_data`` no longer supports ``function`` or ``spatial_subset`` as arguments. To access
an extracted 1D spectrum, use the Spectral Extraction plugin or the automatic extraction of
spatial subsets, and refer to the data-label assigned to the resulting 1D spectrum. [2827]
- Several plugins that take 1D spectra replace ``spatial_subset`` with referring to the 1D
spectrum in ``dataset``. This affects: model fitting, gaussian smooth, line analysis,
and moment maps. [2827]
- Removed deprecated ``cubeviz.select_slice()`` method. Use ``cubeviz.select_wavelength()``
instead. [2878]
- In the Slice plugin, the following deprecated properties were removed: ``wavelength`` (use ``value``),
``wavelength_unit`` (use ``value_unit``), ``show_wavelength`` (use ``show_value``),
``slice`` (use ``value``). [2878]
- Spectral Extraction: renamed ``collapse_to_spectrum(...)`` to ``extract(...)``. [2859]
Imviz
^^^^^
- Deprecated Rotate Canvas plugin was removed; use Orientation plugin instead. [2878]
Mosviz
^^^^^^
Specviz
^^^^^^^
- In the Line Analysis plugin, deprecated ``width`` was removed (use ``continuum_width``). [2878]
Specviz2d
^^^^^^^^^
Bug Fixes
---------
Cubeviz
^^^^^^^
- Moment map plugin now reflects selected flux / surface brightness unit for moment zero. [2877]
- Update the scale factor used to convert a spectrum between surface brightness and flux
to use wavelength-dependent aperture area instead of the cone slice scale factor. [2860]
