 5. NEW FEATURES:
 
+BIASSKIP1 pipeline switch
+
+If the CCD controller has been power cycled less than two hours before taking
+biases, there will be an exponential decay of dark current that will be at
+it's highest level for the first bias.  Set this parameter when running
+kcwi_prep to skip this first bias.  Better yet, wait at least three hours
+after power cycling before taking biases or any science data.
+
+NB: changing binning will cycle the power on the controller.
+
+SKIPOSCANSUB pipeline switch
+
+In rare cases where there is extra flux in the overscan (again close to a
+power cycle event), one may want to skip using the overscan for bias correction.
+This is only implemented if the image has been bias subtracted.

 In order to give the user more control over sky subtraction, we have added
