 - Added the ``mask_treatment`` parameter to Background, Trace, and Boxcar Extract
   operations to handle non-finite data and boolean masks. Available options are
-  ``filter``, ``omit``, or ``zero-fill``, with ``exclude`` additionally available
-  for BoxcarExtract. [#216]

-- Modified BoxcarExtract to ignore non-finite pixels when ``mask_treatment`` is set
-  to ``exclude``; otherwise, non-finite values are propagated. Boxcar extraction is

+- 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.
