Dify 1.17.1 requires a manual staged Weaviate upgrade or vector search breaks silently and permanently
The release opens with a warning that self-hosted deployments using bundled Weaviate move from 1.27.0 to 1.39.2, twelve minor versions, and that skipping minors is unsupported. Pulling and restarting without the staged upgrade can silently and permanently break vector search. Fresh deployments, external Weaviate and other vector stores are unaffected. This is the kind of upgrade note that a `docker compose pull` workflow will walk straight past.
