## New Features
- App-server TUI now supports device-code ChatGPT sign-in during onboarding and can refresh existing ChatGPT tokens. (#14952)
- Plugin setup is smoother: Codex can prompt to install missing plugins or connectors, honor a configured suggestion allowlist, and sync install/uninstall state remotely. (#14896, #15022, #14878)
- Added a `userpromptsubmit` hook so prompts can be blocked or augmented before execution and before they enter history. (#14626)
- Realtime sessions now start with recent thread context and are less likely to self-interrupt during audio playback. (#14829, #14827)
## Bug Fixes
- Fixed a first-turn stall where websocket prewarm could delay `turn/start`; startup now times out and falls back cleanly. (#14838)
- Restored conversation history for remote resume/fork in the app-server TUI and stopped duplicate live transcript output from legacy stream events. (#14930, #14892)
- Improved Linux sandbox startup on symlinked checkouts, missing writable roots, and Ubuntu/AppArmor hosts by preferring system `bwrap` when available. (#14849, #14890, #14963)
- Fixed an agent job finalization race and reduced status polling churn for worker threads. (#14843)
## Documentation
- Refreshed the Python SDK public API docs, examples, and walkthrough around the generated app-server models. (#14446)
## Chores
- Pinned the `setup-zig` GitHub Action to an immutable SHA for more reproducible CI. (#14858)
