Definitions

EOS—the date at which product is removed from the price list and is no longer orderable through the normal, non-exception, order fulfillment process.

EOE—the date after which scheduled maintenance releases will not be produced.

EOL—after this milestone date the software release is no longer supported by Cisco customer support and is removed from CCO.

ED Releases—release goal is to deliver new functionality to the market quickly. Typically there are several ED releases in each train before it goes to GD status. When a train is in the ED stage of its life cycle, delivery of bug fixes will often require moving to the next ED release, which will include new functionality.

GD Release—release goal is stability. The release must meet rigid criteria including defect arrival rate thresholds and a customer feedback survey in order to achieve GD status. A train is designated as "GD-Mature Maintenance" when it is close to EOL.
