+
+Remove automatic global Node polyfill installation from the built-in Vite dev server and instead allow explicit opt-in.
+
+**This is a breaking change for projects using the unstable Vite plugin without a custom server.**
+
+If you're not using a custom server, you should call `installGlobals` in your Vite config instead.
