+# What's new 7.0.0
+## Refactor
+
+- Remove all functions from the `psm1`
+- Move functions into public subdirectory
+- Align TDD and continuous integration workflow for this refactor
+- Move help from functions to mdHelp and use [PlatyPS](https://www.powershellgallery.com/packages/platyPS) to generate external help file
+
+Thanks to [James O'Neill](https://twitter.com/jamesoneill) for the refactor and [Illy](https://twitter.com/ili_z) on the continuous integration.
