Yes they have ... There are in fact few other recorded changes in v10.6.6, limited to one security and two bug fixes:

* The update also copes with a cropping problem when performing postscript printing in landscape mode.

* The lone security fix addresses a man-in-the-middle exploit possible with PackageKit.
