## New Features
- Added `WS_PROXY`/`WSS_PROXY` environment support (including lowercase variants) for websocket proxying in the network proxy. (#11784)
- App-server v2 now emits notifications when threads are archived or unarchived, enabling clients to react without polling. (#12030)
- Protocol/core now carry distinct approval IDs for command approvals to support multiple approvals within a single shell command execution flow. (#12051)
## Bug Fixes
- `Ctrl+C`/`Ctrl+D` now cleanly exits the cwd-change prompt during resume/fork flows instead of implicitly selecting an option. (#12040)
- Reduced false-positive safety-check downgrade behavior by relying on the response header model (and websocket top-level events) rather than the response body model slug. (#12061)
## Documentation
- Updated docs and schemas to cover websocket proxy configuration, new thread archive/unarchive notifications, and the command approval ID plumbing. (#11784, #12030, #12051)
## Chores
- Made the Rust release workflow resilient to `npm publish` attempts for an already-published version. (#12044)
- Standardized remote compaction test mocking and refreshed related snapshots to align with the default production-shaped behavior. (#12050)
