 # Completed Steps
 
-- 2026-09-29: A failed build now fails the deploy with the build's own error
-  instead of a later "failed to inspect image", and the deployment log shows the
-  end of the build output before that error. upaas refuses to build on a Docker
-  Engine older than 18.09, which cannot build with BuildKit. The README's
-  Compose section says to update with `docker compose up -d --build` and names
-  the Docker Engine versions builds need (#234).
-
-- 2026-09-29: The app page shows the app's branch as a label in its title, next
-  to the status badge, instead of after the repository under it (#240).
-
-- 2026-09-29: An app's deployments page now lists only its 10 most recent
-  deployments, newest first, instead of 50 (#238).

 - 2026-09-29: `docker-compose.yml` now sets `UPAAS_PORT` to 8080 as well as
   `PORT`, since upaas reads `UPAAS_PORT` first and a `UPAAS_PORT` in `.env` made
