Summary
This patch release primarily updates internal dependencies, including workerd, and fixes a critical race condition affecting Browser Run on Windows when launching Chrome.
🐛 Bug Fixes
- Fixed a race condition on Windows where Miniflare would fail to connect to Chrome during Browser Run bindings because the WebSocket endpoint was reported ready before the socket accepted connections. Miniflare now probes Chrome's /json/version endpoint with retry/backoff.
- Added retry logic for transient ConnectEx/WSARecv failures when establishing connections to Chrome in browser binding workers.
- Fixed local explorer startup failure in Yarn Plug'n'Play projects by ensuring explorer UI assets are copied to a real temporary directory before registering the workerd disk service.
