As you are aware, we have released SUSE Linux Enterprise 11 Service Pack 1 on June 2 (for all of Server and Desktop, SDK, and High Availability Extension).
With the release of SUSE Linux Enterprise 11 Service Pack 1 the SUSE Linux Enterprise 11 GA (aka Service Pack 0) entered a 6 month parallel maintenance period.
The GA Update tree until December 2nd 2010 will still receive: - Security Updates - Maintenance Updates - and L3 Support
This 6 month overlap period is intended to be a Service Pack 1 migration and deployment help. It does not require any additional subscription to receive updates. A Long Term Service Pack Support extension of the SUSE Linux Enterprise 11 GA branch is not planned.
