The primary change in this release is a change to the behavior of cosmicray_lacosmic. Prior to this version the gain was applied to the input data without updating the units. That has been changed in this version. A more complete description is below. There are two ways to correctly invoke ~ccdproc.cosmicray_lacosmic: Supply a gain-corrected image, in units of electron, and set gain=1.0(the default value) in `cosmicray_lacosmic`. Supply an image in adu and set the gain argument of`cosmicray_lacosmic` to the appropriate value for your instrument. Ideally, pass in a ``gain`` with units, but if units are omitted they will be assumed to be ``electron/adu``.
