======================
Version: October 1999
======================

xslm.cl
    Changed the rej="minmax" parameter settings to reject="minmax" in the
    imcombine calls to avoid confusion with the new rejmask parameter.
    rejmaks should really be set to "" in all the package imcombine calls
    as well but doing so robustly requires making version checks which I
    would prefer to avoid at the moment. (8/6/99, Davis) 

======================
Version: November 1997
======================

reduce.cl

    fileroot now returns a default image type extension based on the imtype
    environment variable.  All other tasks use this default extension
    where ".imh" was explicitly given.  (11/6/97, Valdes)

fileroot.cl
    Added "fits" and "fit" as valid extensions.  (11/6/97, Valdes)

reduce.cl
    Removed changes associated with a tentative change of output log format
    from IMEXAMINE.  (3/31/97, Valdes)

dimsum.cl
magshiftfix.cl
mosaic.cl
registar.cl
shiftfix.cl
shiftset.cl
    Replaced MKIMAGE with MKPATTERN.  (3/31/97, Valdes)

xzap.cl
maskxzap.cl
reduce.cl
    Some temporary files were not being deleted.  (2/4/97, Valdes)

reduce.cl
    1) The calculation of the shifts for IMCENTROID was wrong in that it
       did not use the reference image but used the first image and,
       more significantly, the sign of the shift was wrong.
    2) The filtering of the IMCENTROID output now ignores any Warnings.
    (2/4/97, Valdes)

reduce.cl
    1) Added an unlearn of rimexam and display.
    2) Fixed the other hidden parameters for IMCENTROID.
    (1/31/97, Valdes)
