2.1.6 - Plandex — ContextQMD

The newly released Claude Sonnet 4 is now stable in testing, so it now replaces Sonnet 3.7 as the default model for context sizes under 200k across all model packs where 3.7 was previously used.
A new strong-opus model pack is now available. It uses Claude Opus 4 for planning and coding, and is otherwise the same as the 'strong' pack. Use it with \set-model strong-opus to try it out.
The opus-4-planner model pack that was introduced in 2.1.5 has been renamed to opus-planner, but the old name is still supported. This model pack uses Claude Opus 4 for planning, and the default models for other roles.
Fix for occasional garbled error message when the model is unresponsive.
Fix for occasional 'couldn't aquire lock' error after stream finishes.
Additional retry when model is unresponsive or hits provider rate limits—helps particularly with new Opus 4 model on OpenRouter.
