v1.5.0

New Features

• Added the mask_treatment parameter to Background, Trace, and Boxcar Extract
  operations to handle non-finite data and boolean masks. Available options are
  apply, ignore, propagate, zero_fill, nan_fill, apply_mask_only,
  or apply_nan_only. [#216, #254]

• Modified background.Background.bgk_spectrum to allow the user to select the statistic
  used for background estimation between median or average. [#253]

• Modified extract.BoxcarExtract to ignore non-finite pixels when mask_treatment is set
  to apply; otherwise, non-finite values are propagated. Boxcar extraction is
  now carried out as a weighed sum over the window. When no non-finite values are
  present, the extracted spectra remain unchanged from the previous behaviour.

Bug Fixes

• Fixed Astropy v7.0 incompatibility bug in tracing.FitTrace: changed to use
  astropy.modeling.fitting.DogBoxLSQFitter when fitting a Gaussian peak model instead of
  astropy.modeling.fitting.LevMarLSQFitter that may be deprecated in the future. Also
  changed to use fitting.LMLSQFitter instead of fitting.LevMarLSQFitter when fitting
  a generic nonlinear trace model. [#229]

Other changes

• Changed tracing.FitTrace to use astropy.modeling.fitting.LinearLSQFitter
  if the trace model is linear.
