+'@backstage/test-utils-core': patch
+---
+
+Migrates all utility methods from `test-utils-core` into `test-utils`.
+The entire `@backstage/test-utils-core` is considered deprecated. The package will be removed in a few weeks time.
+This should have almost no impact since this package is primarily used internally by core packages.
+
+Notable changes are that the testing tool `msw.setupDefaultHandlers()` have been deprecated in favour of `setupRequestMockHandlers()`.
