kyvvu-langchain changelog

[1.0.0] - 2026-10-30

Released with kyvvu-engine 1.0.0, at the release set's version; 0.2.0 was never published, and its changes ship here. The 1.0 public surface is listed on the stability page.

  • Changed: depends on kyvvu-templates>=1.0.0,<2.0.0, which now ships the behaviour templates the engine no longer exports.

  • Changed: requires kyvvu>=1.0.0,<2.0.0; 0.1.0's kyvvu<0.24.0 could not install beside kyvvu 1.0.

  • Breaking: requires Python 3.11 or newer (requires-python = ">=3.11"), with kyvvu-engine 1.0.

[0.1.0] - 2026-10-17

  • First release of the LangChain and LangGraph adapters.
  • Each handler declares emitted_events, every event it puts in a template context; a context for any other event is refused. The built-in LangGraph template no longer carries a task.end rule for on_agent_finish, which neither handler emits: the root on_chain_end closes the task.
