+# Jasmine NPM 4.0.1 Release Notes
+
+## Summary
+
+This release fixes loading of files with nonstandard extensions (e.g. .jsx,
+.coffee) in the default configuration by falling back to `require()` when
+`import()` fails because of an unsupported file extension. See
+[#188](https://github.com/jasmine/jasmine-npm/issues/188).
