Currently, we have two types of releases:

  1. Short Term Support (STS) releases that have new features, but also imply regular upgrades.

  2. Long Term Support (LTS) releases that are maintained for a longer duration and provide primarily bug fixes for an extended period of time on a particular release family.

Depending on your choice of the type of the release i.e. LTS or STS, you can identify the type that has been currently installed using one of the following methods: 

  1. By looking for is LTS field in the nCLI version.

  2. By looking for is LTS field in cluster information.

  3. From release tag file contents on the CVM.

  4. From the Zeus configuration printer.

  5. From the upgrade history.
