from being selected with Bokeh v2.3.x and later. [#1177]
Improved TargetPixelFile.interact_sky() by introducing an arrow to
highlight selected stars, adding an aperture_mask argument, and
defaulting to box zoom. [#1082]
Fixed a bug in LightCurve.select_flux() to ensure NORMALIZED header
is set based on the new flux column. [#1094]
Fixed a bug in LightCurveCollection.stitch() which triggered a ValueError
when a mix of normal and masked columns was encountered. [#1182]
Removed the QColumn, QMaskedColumn, and QTimeSeries classes which were
temporarily added in Lightkurve v2.0 to support AstroPy v4.2 and earlier. [#1188]
Fixed a FutureWarning triggered by query_solar_system_objects(). [#1189]
Removed setup.py because pip>=21.3 now enables editable installs to
be executed using the pyproject.toml file instead. [#1185]
Lightkurve v2.1.1 includes the following changes:
Fixed a bug in LightCurve.plot_river() which triggered a
TypeError: cannot write to unmasked output. [#1175]

results in the presence of masked data. [#1172]
Lightkurve v2.1.0 includes the following changes:

Added the cbv_dir parameter to CBVCorrector, load_kepler_cbvs, and
load_tess_cbvs to enable CBVs to be loaded from a local directory. [#1122]
Deprecated download_kepler_cbvs and download_tess_cbvs in favor of
load_kepler_cbvs and load_tess_cbvs. [#1122]

for custom bin sizes. [#1042]
Lightkurve v2.0.11 includes the following changes:
Modified TargetPixelFile.interact_sky() to enable it to work with

Fixed excessive memory usage by LightCurve.bin(). [#1096]
Various improvements to the online documentation. [#1102]
Fixed a bug in TargetPixelFile.estimate_centroids() which caused the column
and row coordinates to be off by 0.5. [#1103]
Fixed a bug which caused a light curve's meta data to be lost after
calling LightCurve.bin(). [#1041]
Modified the BKJD and BTJD AstroPy time formats to use the Barycentric Dynamical Time (TDB) scale by default. [#1112]
Modified LightCurve.create_transit_mask() to accept AstroPy Quantity
objects for period, transit_time, and duration. [#1119, #1141]
Modified CBVCorrector to issue a warning message if the CBVs are
poorly aligned to the input light curve. [#1113]
Fixed a bug in underfit_metric_neighbors() which caused the alignment
of light curves to fail. [#1120]
Removed an unnecessary warning triggered when LightCurve.normalize() is called
on an already-normalized light curve. [#1128]
Fixed an AstroPy warning ("dropping mask in Quantity column") which was encountered when opening a light curve with AstroPy v4.3 installed.
Fixed a bug in TargetPixelFile.animate() which caused a ModuleNotFoundError
to be raised when using older versions of matplotlib. [#1139]
Added a column parameter to LightCurve.truncate(). [#1116]
Lightkurve v2.0.10 includes the following changes:
Modified the search functions to ensure the two parts of K2 Campaigns 9, 10, and 11 are more clearly marked. [#1018]
Fixed a bug in LightCurve which caused left-hand side multiplication
with NumPy floats and AstroPy Quantity objects to fail. [#925]
Fixed a bug which caused TargetPixelFile.to_lightcurve() to fail when
a pixel file lacked the keywords "TUNIT5" or "TUNIT6".
Fixed a bug which caused the column parameter to be ignored in
TargetPixelFile.animate().
Fixed a bug in TargetPixelFile.interact() when ylim_func is specified and
users tap to select custom apertures. [#1033]
Improved the user interface of TargetPixelFile.interact_sky(), including providing
TIC information when applicable. [#1050]
Fixed a bug in search_tesscut().download() when download_dir is specified.
[#1063]
Fixed a bug in LightCurveCollection and TargetPixelFileCollection, where
indexing by slice, e.g., lc_collection[0:2], incorrectly returns a list [#1077]
Added the LightCurve.select_flux() method to make it easier to use a different
column to populate the flux and flux_err columns. [#1076]
Modified the MIT Quicklook Pipeline (QLP) light curve file reader to use the "SAP_FLUX" column as the default flux column. [#1083]
