Cisco Secure Software
The Cisco PIX Firewall product follows the software release designation conventions defined below. While Cisco recognizes the desire by some customers to deploy only General Deployment (GD) software releases, we strongly recommend customers consider the value of deploying current PIX software releases in order to benefit from the many new security features and improvements which can often be found only in more recent Early Deployment (ED) releases.
Release Train
Release Train refers to a major release of the PIX Operating System, e.g., 5.2, 5.3, 6.0, 6.1. Only PIX Operating System releases are given a release designation; PIX Device Manager (PDM) releases are not given a release designation.
Early Deployment ("ED") A release train designated as ED is appropriate for selective deployment within the customer's network where the new features of the release are required. A release train is labeled ED until it achieves GD status.
General Deployment ("GD") A release train designated as GD is appropriate for deployment at all points within the customer's network. The criteria used for declaring a release train GD is based on, but not limited to, time elapsed since the initial release of the train, customer feedback, quality trends over time and other field-reported data. Once a release train achieves GD status, no new feature or platform additions are planned for the release train. In addition, all future maintenance releases of that release train will meet the GD criteria.
