V2.5 (2006-07-14)

COOSYS epoch and system are not set to the proper values in ASCII_VOTABLE

catalogs.

Unexpected crashes are experienced when working with extremely large images

(10+Gpixels). This was not the case with earlier versions (ca. 1999).

V2.3 (2002-12-17)

ASSOC options do not work properly with MEF images (this is not really a bug).
