                       RELEASE NOTES FOR HEASOFT 6.0.6
                               May 16, 2006
******************************************************************************

The HEASoft 6.0.6 release is primarily driven by the release of the Suzaku
software version 1.0, but also includes updates to the ASCA task 'cleansis'
which is used in the Suzaku data processing.

As for previous HEASOFT releases, configuration-related changes thoughout
the package means that users who already have HEASoft v6.0.X installed will
need to completely replace their software installation; there is no clean
way to simply overlay this new release or to update an existing installation.

cleansis:

 - Fixed so that looks for the EVENTS extension and doesn't just use the
   first extension.

 - Allow non-square chips by setting the internal image arrays to the maximum
   of the RAWXCOL and RAWYCOL sizes.
