+### Standalone mode with filename filter
+
+To improve user experience, Vitest will now start running the matched files when [`--standalone`](/guide/cli#standalone) is used with filename filter.
+
+```sh
+# In Vitest v3 and below this command would ignore "math.test.ts" filename filter.
+# In Vitest v4 the math.test.ts will run automatically.
+$ vitest --standalone math.test.ts
+```
+
+This allows users to create re-usable `package.json` scripts for standalone mode.
