-Note that in these old job definitions, the Code Quality image's old versioning
-scheme (e.g. `12-5-stable`) is still being used. But in GitLab 12.6, Code Quality switched to the
-[new versioning scheme](https://gitlab.com/gitlab-org/security-products/codequality/merge_requests/38).
-It is highly recommended to use the vendored template to not worry about manually bumping the image's version,
-but for those who are not yet able to move away from the old job definition, there are [Docker images](https://gitlab.com/gitlab-org/security-products/codequality/container_registry) for
-`12-5-stable`, `12-6-stable`, `12-7-stable`, `12-8-stable`, `12-9-stable`, and `12-10-stable`. These images are just
-copies of `12-4-stable`. No fixes/changes will be backported into these images.
-All further improvements will only be in `0.85.5` onwards. Alternatively, the version (e.g `0.85.5`) can be hardcoded into
