+# [4.0.0](https://github.com/micromata/generator-http-fake-backend/compare/v2.0.1...v4.0.0) (2018-02-19)
+
+*We moved from v2.0.1 to v4.0.0 and skipped v3.x to be on the same major level as the underlying [http-fake-backend](https://github.com/micromata/http-fake-backend) to avoid confusion.*

+>
+  > * The transitive dependency punycode@2.1.0 needs Node version ">=6".
+  > * The setup.js is divided to multiple files.
+Therefore you need to change the import of the setup in your endpoint files
+like the following:
+  > 
+  > ```javascript
+> // before
+> const SetupEndpoint = require('./setup/setup.js');
+>
+> // now
+> const SetupEndpoint = require('./setup/index.js');
+> 
+> // or:
+> const SetupEndpoint = require('./setup/');
+> ```
+
+
+### BREAKING CHANGES
+
+* This project now needs Node 6 or greater.
