Software Lifecycle
Just as our products evolve, so does our software. Our secure, optimized network operating systems and other software are continuously updated to meet customer needs. We use Long Term Support (LTS) releases and maintain the two latest LTS versions along with the latest feature release. Below is a brief overview of the release types and the currently supported versions.
Release Types
LTS Release
A Long Term Support (LTS) release is a release which is supported and maintained for a minimum of four years after release. LTS releases will be released every two years, making them overlap two years with the previous release. When two LTS releases are active at the same time new features is only added to the newest version. For example, if the latest release is referred to as 10.22. When releasing the second LTS release, the number 10 is incremented to 11. The new release will be referred to as 11.00.”
Feature Release
A Feature Release is a minor release which might contain exciting new features and improvements on existing functionality, as well as security enhancements. With a feature release, the second number is incremented. For example, if the current release is referred to as 10.21. When releasing the next feature release, the number 21 is incremented to 22. This new release will then be known as 10.22. Feature releases will only be released to the latest LTS release.
Continuous Improvement Release
Both new features and defect fixes. The new features can be improved or expanded over time. For example: Release 1 can contain a new feature, release 2 could then expand on the new feature like adding more configuration options, release 3 could then further expand on the new feature further refinding the new feature. While also containing fixes for defects
Maintenance Release
A maintenance release focuses on minor improvements on existing features and defect corrections, and for the latest LTS can contain new functionality. With a maintenance release, the third set of numbers are incremented. For example, if the current release is referred to as 10.22.00. When release the next maintenance release, the number 00 is incremented to 01. The new release will then be known as 10.22.01. Maintenance releases will be released for the two active LTS releases and to the latest Feature release.
