Dify released version 1.19.0 on November 4. External traces (Langfuse and other providers) now include the persisted steps inside called Workflow Tools under the invoking Tool span, so nested LLM calls stay in one hierarchy. App packages move to format v2 and can export the workflows behind Workflow Tools (including transitive dependencies), so imports recreate missing tools in the destination workspace. Agents also get parallel multi-file uploads with atomic binding, inline PDF and syntax-highlighted previews, and difyctl commands to list, export, import, and publish workspace Skills. The bundled plugin daemon moves to 0.6.14-local, and Docker Compose 2.35.0 or later is required.
