• No open critical issues introduced in the referenced software release.
• Release deployed in the field for at least three months (unless urgent fixes require the latest release).
• Internal SQA regression testing completed without encountering any new issues.

Feature Release Recommendation

The Feature Release recommendation is the newest version of the software with the latest set of features and is fully supported.

The recommendation reflects the following criteria:

• Less real-world usage history than Maintenance Release.
• Upgrading for fixes may require moving to the next major release, which can include additional new features.

When deploying any software release, customers should always review the Release Notes for known issues that pertain to features and technologies used in their network. Only upgrade above recommendations to fix a specific issue or add a needed feature.
