------------------

New Features
^^^^^^^^^^^^

- The new FitTrace class (see "API Changes" below) introduces the
ability to take a polynomial trace of an image [128]

API Changes
^^^^^^^^^^^

- Renamed KosmosTrace as FitTrace, a conglomerate class for traces that
are fit to images instead of predetermined [128]

- The default number of bins for FitTrace is now its associated image's
number of dispersion pixels instead of 20. Its default peak_method is
now 'max' [128]

- All operations now accept Spectrum1D and Quantity-type images. All
accepted image types are now processed internally as Spectrum1D objects
[144, 154]

- All operations' ``image`` attributes are now coerced Spectrum1D
objects [144, 154]

- HorneExtract can now handle non-flat traces [148]

Bug Fixes
^^^^^^^^^

- Fixed passing a single ``Trace`` object to ``Background`` [146]

- Moved away from creating image masks with numpy's ``mask_invalid()``
function after change to upstream API. This will make specreduce
be compatible with numpy 1.24 or later. [155]

------------------

New Features
^^^^^^^^^^^^

- ``Background`` has new methods for exposing the 1D spectrum of the
background or background-subtracted regions [143]

Bug Fixes
^^^^^^^^^

- Improved errors/warnings when background region extends beyond bounds
of image [127]

- Fixed boxcar weighting bug that often resulted in peak pixels having
weight above 1 and erroneously triggered overlapping background errors
[125]

- Fixed boxcar weighting to handle zero width and edge of image cases
[141]

------------------

New Features
^^^^^^^^^^^^

- ``peak_method`` as an optional argument to ``KosmosTrace`` [115]

API Changes
^^^^^^^^^^^

- ``HorneExtract`` no longer requires ``mask`` and ``unit`` arguments [105]

- ``BoxcarExtract`` and ``HorneExtract`` now accept parameters (and
require the image and trace) at initialization, and allow overriding any
input parameters when calling [117]

Bug Fixes
^^^^^^^^^

- Corrected the default mask created in
``HorneExtract``/``OptimalExtract`` when a user doesn't specify one and
gives their image as a numpy array [118]

------------------

New Features
^^^^^^^^^^^^

- Added ``Trace`` classes

- Added basic synthetic data routines

- Added ``BoxcarExtract``

- Added ``HorneExtract``, a.k.a. ``OptimalExtract``

- Added basic ``Background`` subtraction

Bug Fixes
^^^^^^^^^

- Update ``codecov-action`` to ``v2``

- Change default branch from ``master`` to ``main``

- Test fixes; bump CI to python 3.8 and 3.9 and deprecate support for
3.7
