## New Features
- API v2 threads can now inject dynamic tools at startup and route their calls/responses end-to-end through the server and core tool pipeline. (#9539)
- Added filtering on the thread list in the app server to make large thread sets easier to browse. (#9897)
- Introduced a `thread/unarchive` RPC to restore archived rollouts back into active sessions. (#9843)
- MCP servers can now define OAuth scopes in `config.toml`, reducing the need to pass `--scopes` on each login. (#9647)
- Multi-agent collaboration is more capable and safer, with an explorer role, better collab event mapping, and max-depth guardrails. (#9817, #9818, #9918, #9899)
- Cached `web_search` is now the default client behavior. (#9974)
## Bug Fixes
- Fixed a TUI deadlock/freeze under high streaming throughput by avoiding blocking sends on the main Tokio thread. (#9951)
- The `web_search` tool now handles and displays all action types, and shows in-progress activity instead of appearing stuck. (#9960)
- Reduced high CPU usage in collaboration flows by eliminating busy-waiting on subagents. (#9776)
- Fixed `codex resume --last --json` so prompts parse correctly without conflicting argument errors. (#9475)
- Windows sandbox logging now handles UTF-8 safely, preventing failures when truncating multibyte content. (#8647)
- `request_user_input` is now rejected outside Plan/Pair modes to prevent invalid tool calls. (#9955)
## Documentation
- Updated the contribution guidelines for clearer onboarding and workflow expectations. (#9933)
- Refreshed protocol/MCP docs to reflect `thread/unarchive` and the updated `request_user_input` question shape. (#9843, #9890)
## Chores
- Self-update via Homebrew now uses an explicit cask upgrade command to avoid warnings and ambiguity. (#9823)
- Release packaging now consistently writes the bundle zip to `dist/`. (#9934)
- Updated key dependencies in the Rust workspace (including `axum`, `tracing`, `globset`, and `tokio-test`). (#9880, #9882, #9883, #9884)
- Aligned feature stage naming with public maturity stages and added clearer warnings for underdevelopment features. (#9929, #9954)
