An IPS update has apparently been available since the 7th,

Release Date: 07/Jun/2010
IPS-SSM_20 System Image File

But, I've not been able to find the release notes here, http://www.cisco.com/en/US/customer/products/hw/vpndevc/ps4077/prod_release_notes_list.html
Or by using Cisco's site search.
Or by using google's,
http://www.google.com/search?hl=en&q=site%3Acisco.com+%227.0%283%29E4%22+%22release+notes%22
Can anyone else locate the release notes? URL link if possible, thanks.
