Note

Patch releases: Service software versions that end in "-P" and a number, such as R20211203-P4, are patch releases. Patches are likely to include performance improvements, minor bug fixes, and security fixes or posture improvements. Since patches do not include new features or breaking changes, they generally do not have direct user or documentation impact, which is why the specifics of each patch are not included in this document history.
