Release Notes

New Features - Supported models can now request full-resolution image inspection through both viewimage and codex.emitImage(..., detail: "original"), which helps with precision visual tasks. (14175) - jsrepl now exposes codex.cwd and codex.homeDir, and saved codex.tool(...) / codex.emitImage(...) references keep working across cells. (14385, 14503) - Realtime websocket sessions gained a dedicated transcription mode, plus v2 handoff support through the codex tool, with a unified [realtime] session config. (14554, 14556, 14606) - The v2 app-server now exposes filesystem RPCs for file reads, writes, copies, directory operations, and path watching, and there is a new Python SDK for integrating with that API. (14245, 14435) - Smart Approvals can now route review requests through a guardian subagent in core, app-server, and TUI, reducing repeated setup work on follow-up approvals. (13860, 14668) - App integrations now use the Responses API tool-search flow, can suggest missing tools, and fall back cleanly when the active model does not support search-based lookup. (14274, 14287, 14732) Bug Fixes - Spawned subagents now inherit sandbox and network rules more reliably, including project-profile layering, persisted host approvals, and symlinked writable roots. (14619, 14650, 14674, 14807) - jsrepl no longer hangs when dynamic tool responses contain literal U+2028 or U+2029 characters. (14421) - The TUI no longer stalls on exit after creating subagents, and interrupting a turn no longer tears down background terminals by default. (14816, 14602) - codex exec --profile once again preserves profile-scoped settings when starting or resuming a thread. (14524) - MCP and elicitation flows are more robust, with safer tool-name normalization and preserved toolparams in approval prompts. (14491, 14605, 14769) - The local network proxy now serves CONNECT traffic as explicit HTTP/1, improving compatibility with HTTP proxy clients. (14395) Chores - The subagent wait tool is now consistently named waitagent, aligning it with spawnagent and sendinput.
