🚀 What's New in v1.13.3?

Our latest patch release, v1.13.3, focuses on stability and correctness across workflow execution, streaming, and knowledge retrieval. Here's a quick look at the most important updates:

🎬 New Features

  • Workflow Configuration: Added variable-reference support for model parameters in LLM, Question Classifier, and Variable Extractor nodes by @scdeng in [#33082].

🛠️ Bug Fixes

  • Streaming Reliability: Fixed StreamsBroadcastChannel replay and concurrency issues to keep frontend/backend event delivery stable by @QuantumGhost in [#34030] and [#34061].
  • Workflow Editor Behavior: Fixed pasted nodes retaining Loop/Iteration metadata and prevented HumanInput nodes from being pasted into invalid containers by @majiayu000 and @hjlarry in [#29983] and [#34077].
  • Runtime Execution: Restored prompt message transformation logic and corrected max_retries=0 handling for executor-driven HTTP Request execution by @QuantumGhost, @fatelei, and @kurokobo in [#33666], [#33619], and [#33688].
  • Knowledge Retrieval: Preserved citation metadata in web responses, fixed crashes when dataset icon metadata is missing, corrected hit-count query filtering, and restored indexed document chunk previews by @Theysua, @copilot-swe-agent, and @fatelei in [#33778], [#33907], [#33757], and [#33942].
