Upgrading to 2.3

MODX 2.3 includes many great improvements and new features. The list below is not exhaustive, but highlights the most important changes.

• No more modAction (except for backwards compatibility), instead URL-based routing.
• Namespaces get more powerful (custom TV input types no longer need a plugin but can be read from specific directories)
• Big reduction in number of connectors that need to be installed
• New interface design
• New REST Server classes for developing REST APIs for xPDOObject's easily. Example https://gist.github.com/splittingred/2346752
• (Package Dependency management; need to confirm this made it in)
• Manager themes now use Grunt and Sass, which allows for quick major restyles in custom themes.
• Settings can now be applied on the User Group level
• Contexts can now be renamed
• Possible to disable CSS/JS compression during setup for those pesky servers
• Added "Other" gender for user profiles, to go with the times.
• Added dedicated Media Manager page in the manager
• Make it possible to preview resources even when front-end sessions are disabled
• Add system settings (welcome_action/welcome_namespace) to change the default action after login/when no ?a var is passed.
• Allow editing a resource in a new window by using shift or middle mouse button click on the resource tree
• toPlaceholder output filter no longer returns its value anymore
