Release frequency* - Usually available monthly, but may be around 2-3 months.

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 should not be considered stable. The focus on this release is on on feature enhancements.
Release frequency* - Availability unknown, but is usually released when fixes can be resolved.

Symantec recommends this release only when you require a feature not found in the LTR or Standard release, and you are willing to sacrifice stability for features.
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

Note: Symantec always recommends staying on the latest patch release, on the current branch release you are running, unless a specific fix or feature is required in another release. For example
If you are on 6.5.x upgrade to the latest 6.5 patch release.
If you are on 6.6.x upgrade to the latest 6.6 patch release.
If you are on 6.7.3.x upgrade to the latest 6.7.3 patch release.
If you are on the 6.7.4.x upgrade to the latest 6.7.4 patch release
