## New Features
- Added an experimental code mode for more isolated coding workflows. (#13418)
- Added an experimental hooks engine with `SessionStart` and `Stop` hook events. (#13276)
- WebSocket app-server deployments now expose `GET /readyz` and `GET /healthz` on the same listener for easier health checks. (#13782)
- Added a config switch to disable bundled system skills entirely. (#13792)
- Handoffs now carry realtime transcript context, which improves continuity when work is transferred between turns. (#14132)
- Improved the `$` mention picker by clearly labeling Skills, Apps, and Plugins, and by surfacing plugins first. (#14147, #14163)
## Bug Fixes
- Fixed a Linux `tmux` crash caused by concurrent user-shell lookups. (#13900)
- Fixed apps being enabled in unsupported sessions by tightening the enablement check. (#14011)
- Fixed reopened threads getting stuck as in-progress after quitting mid-run and then resuming later. (#14125)
- Fixed permission handling so legacy `workspace-write` behavior is preserved and newer permission profiles degrade more safely on older builds. (#13957, #14107)
- Fixed approval flows so granted permissions persist across turns, work with reject-style configs, and are honored by `apply_patch`. (#14009, #14055, #14118, #14165)
## Chores
- Laid the groundwork for the Python SDK’s generated v2 schema types and pinned platform-specific runtime binaries. (#13953)
