When will Firefox 3 become End-Of-Life?

Has there been any official word from Mozilla concerning an End-Of-Life date for Firefox version 3? I am supporting Firefox 3 and 11 in a corporate environment and would like to know if we will need to begin phasing out version 3.

Thanks for pointing me in the right direction! I should have been more specific about which version of 3 we are using. We are currently deploying 3.6.x versions. :-)

That was what I figured :) Another thing you can consider if you want to support something a bit more stable without having to support Rapid Release browser versions is Firefox Extended Support Release (ESR) http://www.mozilla.org/en-US/firefox/organizations/ has all the information on that version.
