In the Symantec Endpoint Protection (SEP) product interface or documentation, you may see references to a Release Update or a Maintenance Patch. For release versions, you may see a number with three decimal points, such as 184.108.40.206 or 220.127.116.11. You want more information about what these terms mean, how they relate to the release version number, and how Symantec Endpoint Protection versioning works.
Release terminology definitions
A Major Release is a new software product release that incorporates all updates since the last Major Release. A Major release also provides additional enhancements to the software, such as architectural chances, major feature changes, or new platform or operating system support. A Major Release typically requires a new installation, but does not always.
Reading from left to right, the numbers to the left of the first decimal point typically signify the Major Release version.
A Minor Release updates the previous Major Release. The update incorporates all previous updates since the last Major Release. A Minor Release is tied to the Major Release, and may also contain new features, or new platform or operating system support.
Reading from left to right, the numbers between the first and second decimal point typically signify the Minor Release version.
A Release Update provides low-risk new features or support for additional platforms, in addition to fixes, following the release of Major or Minor Releases.
Reading from left to right, the numbers between the second and third decimal point typically signify the Release Update version.
A Maintenance Patch delivers adaptive, corrective, and perfective low-risk maintenance for Major or Minor Releases. A Maintenance Patch is sometimes also called a Maintenance Pack.
Reading from left to right, the numbers to the right of the third decimal point typically signify the Maintenance Patch version.
For example, for the release version 18.104.22.168:
12 represents the Major Release version.
1 represents the Minor Release version.
6 represents the Release Update version.
8 represents the Maintenance Patch version.
Occasionally, you may see release versions that are expressed using the abbreviations RU (for Release Update) or MP (for Maintenance Patch). For example, you may instead see references to 12.1 RU6 MP8, or more commonly to 12.1.6 MP8. Both are equivalent to 22.214.171.124.
The product release version may be different from the product build version that is found in the product user interface. For a list of build versions as they compare to release versions, see:
How Symantec releases updates for Symantec Endpoint Protection
Symantec releases cumulative updates for Symantec Endpoint Protection. A new Release Update contains new updates and updates from Maintenance Patches that were created for the previous Release Update. Maintenance Patches are created only for the most recent Release Update.
For example, 14.0.1 (14 RU1) includes new updates as well as updates from 14 MP1 and 14 MP2. After the release of 14.0.1, no further Maintenance Patches are created or released for version 14. Instead, they branch off of 14.0.1.
