fallbackModel, glob deny rules, SendMessage authority hardening, and thinking-control fixes shipped in v2.1.166 — here's what each one means for teams running multi-agent pipelines.
Three high-impact Claude Code bugs are now fixed: JetBrains IDE flickering, sessions permanently stuck at 1M context, and a token-wasting image error loop.
The new terminalSequence hook output field lets Claude Code emit OSC escape sequences through its own terminal write path, fixing no-TTY environments.
Codex CLI v0.139.0 lets code mode call web search directly, including from nested JS tool calls, and fixes oneOf/allOf schema preservation for MCP tools.
