Scientific Linux 4 roadmap

Scientific Linux 4 is going to follow the same type of roadmap that we followed for Scientific Linux 3.

• SL 4.9 will be a "legacy" release. It will be supported until the time that RedHat no longer supports RHEL 4, which is February 2012.
  This release will only get minimal support, security updates only. Red Hat calles this the "Production 3 Life Cycle Phase", which is

  During Production 3, at a minimum, qualified security errata of
  important or critical impact and selected mission critical bug fixes
  may be released independent of minor releases.
  
  No new functionality, new hardware enablement or updated installation
  images are planned for release in Production 3 life cycle phase.
  There are no minor releases planned during this phase.
  

• SL 4.0-4.8 will be obsoleted. Currently that is set to October 10, 2010. That date is flexible. We want to give users at least 6 months to update to SL 4.9. So if SL 4.9 takes too long to be released, we will move the October date back.

Summary:
SL 4.0-4.8 : Obsolete in October 2010
SL 4.9 : Minimal support (security only) until February 2012
