There are several types of releases of SGOS for ProxySG and ASG, which offer various levels of stability vs features.
Long Term Release (LTR)
This type of release is considered the most stable, with the following goals: stability, reliability, fit-for-use, FIPS/CC certified, and customer satisfaction.
- Release frequency* - Usually available monthly, but could be around 2-3 months.
- Stability - Considered stable. The recommended release for more customers.
Standard Release (STDR)
This type of release is often considered for its new features, with goals to increase stability and provide security fixes.
- Release frequency* - Available approximately every 3 months (estimated).
- Stability - Stable, but not as stable as the LTR. Symantec recommends staying on the latest release to take advantage of all fixes. This release is recommended only if you require a feature not found in the LTR.
Latest Feature Release
This type of release is the most recent, and generally would not be considered stable. Normally, the focus on this type of release is on feature enhancements. Currently, however, the latest feature release is becoming more stable than generally expected as it is transitioning into its role as Long Term Release (LTR). Therefore, at this time Symantec recommends considering upgrading to the latest feature release for stability as well.
- Release frequency* - Availability unknown, but is usually released when fixes can be resolved.
- Stability - Sacrifices stability for features.
- Symantec highly recommends upgrading with new releases to move toward stability.
- Symantec recommends this release when you require a feature not found in the LTR or Standard release.
Early Availability Release (EA)
This type of release is available early for customers to use in a lab environment. This allows you to test the changes and see how they will affect your current network traffic behavior
- Stability - Tends to have many new features which require testing before being used in a production environment.
*The frequency of releases is subject to change.
