To clarify, 4.0.9 was removed 4.0.10 is the current release.
4.0.9 was released with a significant crypto accelerator problem that
severely impacted ipsec tunnels, and potentially other crypto subsystems on
This was a result of and incorrect ix for a CERT advisory.
The release was only available for a short time before it was pulled and
replaced by 4.0.10 which is the latest stable version.
There should be no reason to downgrade.
Hope this helps.
What Britta is trying to bring to your attention is the fact that the website https://my.securecomputing.com only has version 4.0.8 listed as the latest available version - not version 4.0.10
sorry for the confusion.
will fix asap
