What broke in the modern web stack this week (issue 1)

255 changes shipped across 30 tracked developer tools this week. 2 were critical. Here is what actually needs your attention.

Vercel @vercel/backends@0.8.19

The isolated services and experimentalServicesV2 runtime now emit function output at index instead of svc/service-name/index. This is a breaking change to how service functions are deployed and accessed in production environments.

Do this: Update any code or infrastructure that references the old svc/service-name/index path to use the new index path before deploying.

Release notes

Liveblocks v3.20.1

A bug in @liveblocks/client could cause data loss by overwriting room storage with initial values when large WebSocket messages are sent. This is a critical fix for a stable release that users in production must deploy immediately.

Do this: Update to v3.20.1 immediately to prevent data loss from large WebSocket messages overwriting room storage.
