Dify: v1.9.2 - Sharper, Faster, and More Reliable

This release focuses on improving stability, async performance, and developer experience. Expect cleaner internals, better workflow control, and improved observability across the stack. --- > [!WARNING] > > A recent change has modernized the Dify integration for Weaviate (see PR #25447 and related update in PR #26964). The upgrade switches the Weaviate Python client from v3 to v4 and raises the minimum required Weaviate server version to 1.24.0 or newer. With this update: > > - If you are running an older Weaviate server (e.g., v1.19.0), you must [upgrade](https://docs.weaviate.io/deploy/migration) your server to at least v1.24.0 before updating Dify. > - The code now uses the new client API and supports gRPC for faster operations, which may require opening port 50051 in your Docker Compose files. > - Data migration between server versions may require re-indexing using Weaviate’s Cursor API or standard backup/restore procedures. > - The [Dify documentation](https://docs.dify.ai/en/self-host/troubleshooting/weaviate-v4-migration#weaviate-migration-guide-upgrading-to-client-v4-and-server-1-27) will be updated to provide migration steps and compatibility guidance. > > **Action required:** > - Upgrade your Weaviate server to v1.24.0 or higher. > - Follow the migration guide to update your data and Docker configuration as described in the latest official Dify documentation. > - Ensure your environment meets the new version requirements before deploying Dify updates. --- ## ✨ Highlights **Workflow & Agents** -
