New Features
- Windows sandbox runs can now enforce proxy-only networking with OS-level egress rules, instead of relying on environment variables alone. (#12220)
- App-server clients can now start ChatGPT sign-in with a device code flow, which helps when browser callback login is unreliable or unavailable. (#15525)
codex execnow supports the prompt-plus-stdin workflow, so you can pipe input and still pass a separate prompt on the command line. (#15917)- Custom model providers can now fetch and refresh short-lived bearer tokens dynamically, instead of being limited to static credentials from config or environment variables. (#16286, #16287, #16288)
Bug Fixes
- Project-local
.codexfiles are now protected even on first creation, closing a gap where the initial write could bypass normal approval checks. (#15067) - Linux sandbox launches are more reliable because Codex once again finds a trusted system
bwrapon normal multi-entryPATHs. (#15791, #15973) - The app-server-backed TUI regained several missing workflows: hook notifications replay correctly,
/copyand/resume <name>work again,/agentno longer shows stale threads, and the skills picker scrolls past the first page. (#16013, #16021, #16050, #16014, #16109, #16110) - MCP startup is more robust: local servers get a longer startup window, and failed handshakes surface warnings in the TUI again instead of looking like clean startups. (#16080, #16041)
- On Windows,
apply_patchis less likely to fail because it no longer adds redundant writable roots that could trigger unnecessary ACL churn. (#16030)
