• Dropped support for Python 3.9. The minimum supported Python version is now 3.10. All workflows, poetry configuration, and dependencies have been updated accordingly.
• Refactored documentation: migrated from MkDocs to Mintlify/Mdx style, overhauled all docs to .mdx and .json formats, updated navigation and assets, and removed material/mkdocs build files and static assets.
• Refactored and unified the tool system under rigging.tool. The Tool, @tool, @tool_method, robopages, and mcp interfaces have replaced previous ApiTool and native Tool abstractions. Tool usage in pipelines is now consistent and all tool APIs are migrated to the new system.
• Major internal rewrite of ChatPipeline and associated pipeline flow:
  • Removed until() and legacy internal pipeline control, replaced with then() and map() callback-based interface using PipelineStep, step(), and ContextManager/AsyncGenerator patterns.
  • until_parsed_as() parameters changed: removed/deprecated max_rounds, attempt_recovery, and drop_dialog, added/renamed to max_depth.
  • Exception for exceeding rounds changed from MessagesExhaustedMaxRoundsError to MaxDepthError. Update exception handling in calling code.
• Unified handling of message content and modality:
  • Standardized Message.content as text-only; use Message.content_parts for full content, including multimodal parts.
  • Added ContentAudioInput type for audio.
  • Updated serialization logic for message content parts, API specs, and cross-provider compatibility.
• Changed the handling of retries and error catching in pipelines:
  • Replaced errors_to_fail_on with errors_to_catch.
  • All catchable errors during pipeline execution now use the catch list and unified on_failed handling for "raise", "skip", or "include".
• Set the default merge_strategy in ChatPipeline.add to "none". Messages of the same role are not merged unless explicitly requested.
• Added .cache() method on ChatPipeline for controlling prompt caching hints (experimental).
• Updated dependencies: latest litellm, openai, and added support for mcp and related protocol support libraries.
• Cleaned up public API: removed the unused integrations module; imported all new public symbols (tool_method, mcp, robopages, etc.) from root.
• Small fixes and formatting: reformatted code to 100 columns, improved CLI argument formatting, and upgraded ruff config/ignore list.
• Removed all previously auto-generated API documentation markdown in favor of new Mintlify/mint-style navigation and layout.
• The example and code remains backwards-compatible for basic usage but some advanced pipeline usage will require adaptation.
