OpenAI released Codex rust-v0.166.0 on 29 October, adding keyboard-driven transcript selection, a codex queue --resume option and a codex doctor --network-only diagnostic. The release also adds GPT-6.1 Terra to the bundled, Vertex AI and Amazon Bedrock model catalogs.

The release adds keyboard-driven transcript selection with word, line and page motions, plus integrated search and configurable shortcuts. Markdown now renders consistently in async questions, choices, answers and transcript replies. Safety-block messages in the TUI now include clearer explanations and selectable safer follow-up prompts.

New commands cover queueing and diagnostics. codex queue --resume resumes unloaded threads after a message is queued, and codex doctor --network-only runs focused checks for configuration, connectivity and WebSocket. GPT-6.1 Terra is available in the bundled, Vertex AI and Amazon Bedrock model catalogs.

Bug fixes preserve approval and permission settings when threads are resumed or forked, restore spawned descendant threads when a parent is unarchived, and keep reasoning-token accounting across resume and fork. The changelog also notes that Bazel now builds V8 from source and that development and release builds use Node.js 24.22.1 and Rust 1.95.0.

## Why it matters if you build agents

Developers who script Codex sessions can use codex queue --resume to pick up threads after queueing a message. The codex doctor --network-only check offers a quicker way to test connectivity and WebSocket reachability when agent runs fail on the network. Teams that pin toolchains should note the move to Node.js 24.22.1 and Rust 1.95.0 for builds.
