Release Notes
New Features - Added WSPROXY/WSSPROXY 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.
