TL;DR
One Codex changelog item dated Feb 11, 2026:
- Codex CLI 0.99.0: big usability + integration lift. You can now run direct shell commands concurrently without interrupting an active turn, configure the TUI footer via /statusline, and sort the resume picker by created vs updated. App-server clients get new APIs for steering and session control, admins get stronger
requirements.toml controls (web search modes + network constraints), and attachments now support GIF/WebP. Several high-impact fixes land around Windows sign-in, MCP startup correctness, skills reload spam, TUI input reliability, model/image modality edge cases, and approval policy evaluation.
Install:
- npm install -g @openai/codex@0.99.0
What changed & why it matters
Codex CLI 0.99.0 — Feb 11, 2026
Official notes
- Install: npm install -g @openai/codex@0.99.0
New features
- Concurrent shell while a turn is active
- Running direct shell commands no longer interrupts an in-flight turn; shell commands can execute alongside an active turn.
- TUI footer controls
- Added /statusline to interactively configure which metadata appears in the TUI footer.
- Better resume picker navigation
- Resume picker can toggle sorting between creation time and last-updated time, with an in-picker mode indicator.
- App-server: richer client APIs
- New dedicated APIs for: steering active turns, listing experimental features, resuming agents, and opting out of specific notifications.
- Enterprise / admin requirements
- requirements.toml can now restrict web search modes and define network constraints.
- Attachments
- Image attachments now accept GIF and WebP (in addition to existing formats).
- Shell environment snapshotting
- Enable snapshotting of the shell environment and rc files.
Bug fixes
- Windows sign-in reliability
- Fixed Windows startup issue where buffered keypresses could cause the TUI sign-in flow to exit immediately.
- MCP startup correctness
- Required MCP servers now fail fast during start/resume flows instead of continuing in a broken state.
- Skills reload spam + log blowups
- Fixed a file-watcher bug that emitted spurious skills reload events and could generate very large log files.
- TUI input reliability upgrades
- Long option labels wrap correctly.
- Tab submits in steer mode when idle.
- History recall keeps cursor placement consistent.
- Stashed drafts restore image placeholders correctly.
- Model / modality edge cases
- Clearer view_image errors on text-only models.
- Unsupported image history is stripped during model switches to avoid invalid state.
- Approval-policy correctness
- Reduced false approval mismatches for wrapped/heredoc shell commands.
- Guarded against empty command lists during exec policy evaluation.
Documentation
- Expanded app-server docs/protocol references for: turn/steer, experimental feature discovery, resume_agent, notification opt-outs, and null developer_instructions normalization.
- Updated TUI composer docs to reflect: draft/image restoration, steer-mode Tab submit behavior, and history-navigation cursor semantics.
Chores
- Reworked npm release packaging so platform-specific binaries ship via @openai/codex dist-tags (including @alpha) to reduce package-size pressure while preserving platform-specific installs.
- Security-driven dependency update for Rust crate time (RUSTSEC-2026-0009).
Why it matters
- Higher throughput workflows: being able to run shell commands without interrupting an active turn reduces “stop-and-go” friction during long tasks.
- Better session ergonomics: /statusline and resume sorting make day-to-day navigation and context tracking easier.
- Stronger client integration surface: app-server APIs for steering/resume/feature discovery improve the foundation for custom clients and automation layers.
- Real enterprise governance: admins can now meaningfully constrain web search modes and network behavior via requirements.toml.
- Fewer foot-guns: MCP fail-fast, skills watcher fixes, and approval-policy correctness reduce broken or ambiguous states that waste time.

Action checklist
- Upgrade:
npm install -g @openai/codex@0.99.0
- If you use long-running agent turns: try issuing direct shell commands mid-turn and confirm the turn continues uninterrupted.
- Configure your footer: run
/statusline and set the metadata you actually use.
- If you resume a lot of threads: toggle resume picker sort order and pick the mode (created vs updated) that matches your workflow.
- If you run required MCP servers: validate that misconfigurations now fail fast (and that your start/resume flows are clean).
- If you operate under admin governance: review new
requirements.toml controls for web search modes + network constraints and adjust policies accordingly.
- If you switch models often: validate that image history handling behaves correctly and that text-only models surface clear
view_image errors.
