Cline 4.1.20 runs sibling sub-agents' tool calls in parallel and restores hook-injected context
Cline v4.1.20 (2026-09-22) runs tool calls from sub-agents spawned in the same step concurrently, while keeping ordered tools sequential. It also fixes a regression where contextModification returned by UserPromptSubmit and TaskStart hooks was silently dropped, so hooks that injected repository facts had been doing nothing. The default output budget is now 30% of a model's advertised limit, and 36 providers without a pinned model now resolve to a different default, mostly DeepSeek V4.1 Flash, GLM 5.3 Flash or MiMo V2.6 Flash. Pin your model if you depend on it.
