• Added a column parameter to LightCurve.truncate(). [#1116]

Lightkurve v2.0.10

• 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]

  TIC information when applicable. [#1050]

  [#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]
