 The biggest change introduced in the new version of Scaladoc is the change of the default language for docstrings. So far Scaladoc only supported Wikidoc syntax.

 One of the experimental features of Scaladoc will be a snippets compiler. This tool will allow you to compile snippets that you attach to your docstring
