Same-day-as-deploy upgrade: image swapped to seafileltd/seafile-pro-mc:13.0-latest, elasticsearch:8.15.0 added as new compose service for Pro's full-text search. Free Pro tier (<=3 users, no license). Existing data + users survived.
Also documented the Caddy patch stripping IETF resumable-upload headers (Upload-Draft-Interop-Version etc.) so the iOS Seafile Pro 4.0.2 app falls back to plain multipart upload; without it large uploads stalled and cancelled after ~60s.
