So far I've only seen notification for HP-UX, but the 9.03 patch bundle has been released.
As expected, this is almost entirely a bug-fix release. The only new features are some extensions to encrypted communication and control, and an SSL update.
But the bug-fix list is very, very long. I counted around 140+ bug fixes, covering Oracle, SQL, StoreOnce, VEPA (especially vmware), omnidbutil, reporting and many, many other areas.
P.S. If you are running version 9, you will probably find my books on it very helpful -- http://www.ifost.org.au/books/#dp to buy it on paper, as a PDF or in Kindle format.
