Summary

Added requirement for automatic upgrade to latest patch versions before Extended Support enrollment to ensure security updates

Security assessment

The change explicitly states that automatic upgrades to specific patch versions are required to receive security updates during Extended Support. This directly addresses security maintenance by ensuring clusters receive security patches, making it both security-related and adding security documentation.

+Extended Support will only be offered for the latest supported patch version of each major Redis OSS version. When Extended Support begins on February 1, 2026, if your Redis OSS v4 and v5 clusters are not already on the latest patch versions, they will be automatically upgraded to v4.0.10 for Redis OSS v4, and v5.0.6 for Redis OSS v5, before being enrolled in Extended Support. This ensures that you receive security updates and bug fixes through Extended Support. You do not need to take any action to upgrade to these latest patch versions as part of the Extended Support transition.
