- Continued clean-up work for Restlet Framework documentation
 - Removed the outdated user guide for versions before 2.2 (the upcoming new stable version) as it will be impossible to maintain in the long run due to the format changes between Daisy Wiki and GitHub Markdown
 - Moved What's new pages for deleted user guides into the 2.2 guide so that migration and changes info is still available
 - Fixed Javadocs index pages
