Codex 0.145.0 introduces experimental paginated thread history with efficient resume and persistent names, plus multi-agent V2 with configurable sub-agent models and improved navigation. Audio inputs and streaming realtime V3 conversations are now supported. The /import command now migrates settings from Cursor and Claude Code. Amazon Bedrock login and custom endpoints are available experimentally, with GPT-5.6 Sol as the default model. Editing earlier prompts now creates contextual branches preserving conversation history.
