New Features
- TUI markdown now keeps web links clickable with OSC 8 metadata, and cramped tables switch to readable key/value records without losing link targets. (#24472, #24636, #24825)
- Sessions can now be archived from the TUI with
/archiveor from the CLI withcodex archive/codex unarchive; archived sessions are protected from resume/fork until restored. (#25027, #25021) - App-server integrations can resume a thread with its initial turns page, see richer MCP server status, and launch stdio mode with
codex app-server --stdio. (#23534, #24698, #24940) - Remote execution setup now supports
CODEX_API_KEYregistration for approved OpenAI hosts, while remote-control websockets use short-lived server tokens instead of ChatGPT access tokens. (#24666, #24141) - Windows admins get an alpha
codex sandbox setup --elevatedprovisioning path, plus requirements support for allowed Windows sandbox implementations. (#24831, #23766) - A feature-gated standalone image generation extension can run through the native Codex image artifact completion pipeline. (#24723, #24972)
Bug Fixes
- ChatGPT auth refreshes tokens before the five-minute expiry window and shows a relogin-required path for reused refresh tokens instead of collapsing into a generic cloud error. (#23546, #24830)
- Command-safety hardening prevents
/difffrom running repository-provided Git helpers/hooks, avoids PowerShell parser execution on non-Windows hosts, and rejects browser-origin exec-server websocket handshakes. (#24954, #24946, #24947) - Sandboxed commands clean up more reliably after interruptions or denied Windows network attempts, and
denyread rules stay enforced for safe-command and approval-bypass paths. (#22729, #19880, #23943) - Resumed TUI sessions seed prompt history from the session transcript, multiline hook output renders as separate rows, and Vim normal-mode editing behaves correctly. (#24298, #24965, #25022)
- App-server filesystem watchers debounce later batches correctly, and standalone web search calls now show and restore completed search activity. (#24716, #24693)
- Bedrock auth now falls back to
AWS_REGION/AWS_DEFAULT_REGION, and unsupported Bedrock GPT service tiers are no longer advertised or sent. (#25171, #25318)
Documentation
- Python SDK beta docs and package metadata now present the standard
pip install openai-codexpath, refreshed quickstarts, API reference, FAQ, and examples. (#24836, #24866, #24868, #24870) - Python SDK examples and docs now use the public
CodexConfigname for configuringCodex/AsyncCodex. (#24800) - The bundled OpenAI Docs skill was updated with current Codex manual routing and a cached manual fetch helper. (#24914)
- Built-in tool schema descriptions now clarify defaults, optional fields, bounds, and enums across shell, Code Mode, MCP, image, goal, plan, multi-agent, and related tools. (#24794)
- App-server and exec-server docs now cover API-key remote registration,
--stdio, runtime extra skill roots, and remote-control server-token behavior. (#24666, #24940, #24977, #24141)
Chores
- Python SDK releases can now be staged and published independently from runtime releases using
python-v*tags while preserving the reviewed runtime dependency pin. (#24828, #24872) - Updated MCP dependencies to
rmcp1.7.0 and refreshed compatibility code. (#24763) - Refreshed Amazon Bedrock catalog metadata, including GPT-5.5, removal of unsupported OSS entries, and default-tier-only GPT model behavior. (#24701, #24960, #25318)
- Removed the stale app-server debug-client pieces and cleaned up the workspace after deletion. (#25063, #25064, #25065, #25066, #25067, #25068, #25069, #25070, #25075)
- Trimmed CI/build maintenance by moving Bazel Windows jobs to Codex runners, removing the libubsan workaround, and reverting the startup benchmark that broke musl builders. (#24952, #24782, #24937)
