 For self-managed Grafana (both Enterprise and OSS), the support for versions is as follows:
 
-- Support for each minor release extends to nine months after the release date.
-- Support for the last minor release of a major version is extended an additional six months, for a total of 15 months of support after the release date.
+- Each minor release is supported for 9 months after its release date
+- The last minor release of a major version receives extended support for 15 months after its release date
+- Support levels change as new versions are released:
+  - **Full Support**: The most recently released major/minor version receive full support including new features, bug fixes, and security patches
+  - **Security & Critical Bugs Only**: Versions that are outside of the most recently released major/minor version, but still within their support period, receive only security patches and critical bug fixes
+  - **Not Supported**: Versions beyond their support period receive no updates
