+    Due to historical reasons, small Linux SaaS Runners had a lot of tags attached because they were used as labels. We want to streamline the tag to just use `saas-linux-small-amd64` and be consistent across all SaaS runners.
+
+    We are deprecating the tags: `docker`, `east-c`, `gce`, `git-annex`, `linux`, `mongo`, `mysql`, `postgres`, `ruby`, `shared`.
