Lightkurve

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

- Fixed a bug which caused the ``step`` and ``interval`` parameters
to be ignored in ``TargetPixelFile.animate()``.

- Modified ``TargetPixelFile.pipeline_mask`` to return a default mask
if the aperture extension is missing from the file.

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

- Added support for reading CDIPS light curves. [980]

- Fixed a bug which caused ``LightCurve`` object instantiation to fail if
a string-typed column had a unit set. [980]

- Fixed a bug in ``CBVCorrector`` causing it to not work on K2 data. [1012]

- Modified ``LightCurveCollection`` to have a more simple and generic ``__repr__()``
which does not group objects by target id. [1002]

- Fixed a bug in ``LightCurveCollection.plot()`` which caused an incorrect y label
when the collection contained normalized and non-normalized light curves. [1002]

- Modified the search functions to make the ``exptime`` parameter case-insensitive.

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

- Removed ``ipython`` from the installation requirements. [999]

- Added the ``LightCurve.to_excel()`` convenience method. [1000]

- Added a new tutorial demonstrating how to load a light curve
into Excel.

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

- Removed ``numba`` from the installation requirements and modified
``SparseDesignMatrix`` to no longer use ``numba.jit``. [997]

- Modified ``LightCurve.bin()`` to partially restore the ``bins`` parameter which
was available in Lightkurve v1.x, to improve backwards compatibility. [995]

- Modified ``LightCurveCollection.stitch()`` to ignore incompatible columns
instead of having them raise a ``ValueError``. [996]

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

- Added the ``TargetPixelFile.animate()`` feature to display Target Pixel Files
as HTML animations inside Jupyter notebook environments. [991]

- Fixed a bug in ``SFFCorrector`` which caused ``prior_mu`` and ``prior_sigma``
to be Quantity objects rather than arrays. [982]

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

- Added support for reading KEPSEISMIC light curves. [972]

- Modified the top-level namespace of lightkurve to include the contents of
`lightkurve.correctors` again. This was removed in 2.0.0 to speed up
`import lightkurve`, but the change affects too many existing packages. [977]

- Fixed a bug affecting the alignment of vectors in ``CBVCorrector``. [964]
