AWS AmazonRDS: Clarify RDS for Oracle RU/MRP naming and patch application
Summary
Rewrites the description of Release Update (RU) and Monthly Recommended Patch (MRP) naming, explaining that the mrp-date identifies the most recent MRP applied on top of the RU, that an MRP includes a Critical Security Patch Update (CSPU), and that automatic minor version upgrades apply quarterly RUs but not MRPs (which must be applied manually).
Security assessment
The change is a documentation clarification of engine version naming and patch application behavior. It mentions that MRPs include a Critical Security Patch Update and that MRPs between quarterly RUs must be applied manually, which is security-relevant guidance about staying patched, but it does not address a specific vulnerability or incident.
Evidence
+The naming format for an RU is as follows: ``release`.ru-`date`.mrp-`date`.r`rnumber`` for July 2026 and later, and ``release`.ru-`date`.rur-`date`.r`rnumber`` for April 2026 and earlier. Beginning in July 2026, the second date segment of an RU name uses the `mrp` prefix instead of `rur`. The `mrp-date` identifies the most recent Monthly Recommended Patch (MRP) applied on top of the RU. An MRP includes a Critical Security Patch Update (CSPU) and other fixes that Oracle recommends. In a quarterly RU engine version, the `mrp-date` matches the `ru-date`, which means that no MRP is applied on top of the RU. For example, the RDS for Oracle RU for July 2026 is named `19.0.0.0.ru-2026-07.mrp-2026-07.r1`, whereas the RU for January 2025 is named `19.0.0.0.ru-2025-01.rur-2025-01.r1`.
