4.0.0

Migration

# command/entrypoint now match Docker Compose semantics — swap them if you used `command:` to override ENTRYPOINT
entrypoint: ["/docker-entrypoint.sh"]
command: ["nginx", "-g", "daemon off;"]

# mounts.readonly → mounts.read_only
mounts:
  /etc/nginx/:
    read_only: true

# stop_grace_period example was misleading (always was nanoseconds)
stop_grace_period: 10000000000  # 10s

First swarm-app diff after upgrading will show a cosmetic diff on services using configs: (Mode now explicit 0o444). Redeploy clears it.
