## New Features
- Add multi-conversation “agent control” so a session can spawn or message other conversations programmatically (#8783, #8788)
- Add app-server `thread/rollback` so IDE clients can undo the last N turns without rewriting history (#8454)
- Add `web_search_cached` to enable cached-only Web Search results as a safer alternative to live requests (#8795)
- Allow global exec flags (model/json/sandbox toggles, etc.) to be passed after `codex exec resume` (#8440)
- Show time/version-targeted announcement tips in the TUI, driven by a TOML file in the repo (#8752)
- Add an `[analytics] enabled=...` config section to control analytics behavior (#8350)
## Bug Fixes
- Fix TUI2 transcripts so streamed markdown reflows on resize and copy/paste preserves soft wraps (#8761)
- Make `apply_patch` parsing tolerant of whitespace-padded `*** Begin Patch` / `*** End Patch` markers (#8746)
- Render paths relative to the current working directory before checking git roots, improving output in non-git workspaces (#8771)
- Prevent `CODEX_MANAGED_CONFIG_PATH` from overriding managed config in production, closing a policy bypass (#8762)
- Ensure app-server conversations respect the config passed in by the client (#8765)
- Reduce TUI UX glitches: suppress popups when browsing input history, fix copy “pill” rendering, and clear background terminals on interrupt (#8772, #8777, #8786)
## Documentation
- Clarify onboarding/login guidance for headless/remote setups by steering users to `codex login --device-auth` (#8753)
- Update model examples used in tooling/config to current `gpt-5.2` naming (#8566)
## Chores
- Refactor skills discovery to use the config layer stack so all configured skill folders are considered (#8497)
- Auto-populate GitHub release notes at release creation time (#8799)
- Add more `apply_patch` test scenarios to harden coverage (#8230)
- Tweak unified exec event emission to only send “begin” when a PTY is present (#8780)
