security patches?

[kingxerxes]

hello,
i am running the following version:

ispCP 1.0.7 OMEGA
build: 20101022
Codename: Priamos

this is in a production environment, so I dont want to upgrade to 1.1.0 yet. what i was wondering is whether there are any security patches that need installing.

i remember getting some emails market URGENT regarding security a while ago, but i cannot find them now and am not sure if they apply to this version or not?

many thanks!
