Cline 4.1.13

Original release notes

Everything here lands through the SDK bundle, so it applies to windows running that bundle.

Fixed

  • Restore tool calling for custom OpenAI-Compatible models whose capability list was inferred from convenience flags like supportsReasoning. The inferred list read as an authoritative denial and stripped every tool from the request; an explicitly authored capability list still decides.
  • Keep Hub-backed sessions intact across a Hub restart or upgrade. Clients replay the events they missed while disconnected, and the same event is no longer delivered twice when the replay and live streams overlap.
  • Carry session and client identity into Langfuse traces for Hub-backed and delegated-agent runs, which previously arrived without their session grouping or client version.
