Monthly release versions do not enjoy regular patch releases like MTS and LTS versions do. Bugs found in monthly release versions are directly resolved in the subsequent monthly release.

For example, if a bug is found in version 9.1, it will only be fixed in the next monthly release, which would be version 9.2.
For example, if a bug is found in version 10.1, it will only be fixed in the next monthly release, which would be version 10.2.

### Release Cycle

A monthly release only receives patches for critical/security issues if they can be released earlier and faster than the next minor version release. Otherwise, bugs found in a monthly release will only be fixed rolling forward to the next minor version.

For example, if you are using version 9.1 after 9.2 has been released and you find a critical issue in 9.1, that fix will only be released in the next monthly release, which would be 9.3.
For example, if you are using version 10.1 after 10.2 has been released and you find a critical issue in 10.1, that fix will only be released in the next monthly release, which would be 10.3.

If a bug is found in a monthly-release version for an older major version, it will only be fixed as a patch on the existing LTS (for example, a bug found in 9.16 will only be fixed for a patch release on the LTS version 9.24).
