 # Completed Steps
 
+- 2026-09-29: An image built from the `Dockerfile` now shows the commit it was
+  built from (the `git describe` output) in the footer and `/health` instead of
+  `dev`: `.dockerignore` no longer leaves out `.git`, nor any tracked file,
+  which git would count as deleted and mark `-dirty`. upaas now also logs its
+  version at startup; the logger's `Identify()` was never called (#236).

   to the status badge, instead of after the repository under it (#240).
