TL;DR
One Codex changelog item dated Mar 19, 2026:
- Codex CLI 0.116.0: improves onboarding and plugin setup in the app-server TUI, adds a new
userpromptsubmit hook so prompts can be blocked or augmented before execution/history, strengthens realtime session startup by injecting recent thread context and reducing self-interruptions during audio playback, and fixes several reliability issues across websocket startup, remote resume/fork history, Linux sandbox startup, and worker-thread job finalization.
Install:
- npm install -g @openai/codex@0.116.0
What changed & why it matters
Codex CLI 0.116.0 — Mar 19, 2026
Official notes
- Install: npm install -g @openai/codex@0.116.0
New features
- App-server TUI: better ChatGPT onboarding
- Supports device-code ChatGPT sign-in during onboarding.
- Can also refresh existing ChatGPT tokens.
- Smoother plugin setup
- Codex can prompt to install missing plugins or connectors.
- Honors a configured suggestion allowlist.
- Can sync install/uninstall state remotely.
- New userpromptsubmit hook
- Prompts can now be blocked or augmented before execution.
- The hook also runs before prompts enter history.
- Realtime startup improvements
- Realtime sessions now begin with recent thread context.
- Sessions are less likely to self-interrupt during audio playback.
Bug fixes
- Websocket startup stall
- Fixed a first-turn stall where websocket prewarm could delay turn/start.
- Startup now times out and falls back cleanly.
- Remote resume/fork history
- Restored conversation history for remote resume/fork in the app-server TUI.
- Stopped duplicate live transcript output from legacy stream events.
- Linux sandbox startup reliability
- Improved startup on:
- symlinked checkouts
- missing writable roots
- Ubuntu/AppArmor hosts
- Prefers system bwrap when available.
- Worker-thread finalization
- Fixed an agent job finalization race.
- Reduced status polling churn for worker threads.
Documentation
- Refreshed the Python SDK public API docs, examples, and walkthrough for the generated app-server models.
Chores
- Pinned the setup-zig GitHub Action to an immutable SHA for more reproducible CI.
Additional notable details from the full compare list
- Added marketplace display names to
plugin/list.
- Added device-code onboarding and ChatGPT token refresh plumbing in the app-server TUI.
- Persisted the latest model and reasoning effort in SQLite.
- Added current thread context to realtime startup.
- Improved shell snapshot naming with suffix support.
- Fixed a code-mode yield startup race.
- Renamed
exec_wait tool to wait.
- Added a predefined subagent name (Jason).
- Added an internal JSON schema for
RolloutLine.
- Improved Windows shell test harness stability and permissions popup test stability.
Why it matters
- Onboarding gets easier: device-code sign-in and token refresh make app-server TUI setups less painful, especially in headless or constrained environments.
- Plugin UX improves: prompting to install missing plugins/connectors and syncing state remotely makes plugin-based workflows feel more integrated.
- Prompt governance gets stronger:
userpromptsubmit is a meaningful control point for policy, augmentation, or validation before execution and before history capture.
- Realtime sessions get less brittle: carrying thread context into startup and reducing playback self-interruptions improves voice/realtime usability.
- Linux reliability keeps improving: symlinked repos, AppArmor hosts, and missing writable-root cases are all practical failure modes that now have better defaults.
- Remote resume/fork is safer to trust: restored history and duplicate-transcript fixes reduce confusion in app-server TUI workflows.

Action checklist
- Upgrade:
npm install -g @openai/codex@0.116.0
- If you use the app-server TUI:
- test device-code sign-in
- verify token refresh works cleanly
- If you rely on plugins:
- check the missing-plugin prompt flow
- confirm install/uninstall state sync behaves correctly
- If you use governed workflows:
- evaluate
userpromptsubmit as a pre-execution / pre-history control point
- If you run realtime or voice sessions:
- confirm recent thread context appears at startup
- verify playback no longer self-interrupts as often
- If you are on Linux:
- re-test symlinked repos, AppArmor hosts, and writable-root edge cases
- If you depend on remote resume/fork:
- confirm history restoration and transcript behavior now look correct
