I don't know...
But do you know where can I download the SP2 (835-2161) and SP3 (2161-2290)?
I can't download them because the link of the Auran website is a failure.
Auran's web says: Service Pack 4 is only available for download right now. Once all patches have been completed they will be made available on CD from the online store for the cost of postage and handling.
Thanks!
