Page Theme classes can specify layout presets, which can use classes contained in grid frameworks or use their own custom classes.
Layouts now have design controls available to them, including custom templates and custom CSS classes.
Added a new custom template “Parallax Image” available to layouts that employ a background image.
Grid frameworks can now specify hiding classes for responsive breakpoints, which can be controlled through block and area design settings.
Grid containers that wrap around blocks based on their type can now be disabled or enabled on a per-block basis through the block design palette.
Added nested support to grid frameworks.
Mobile Improvements
Completely new Mobile Device Preview panel in the page panel. Preview the current page in a variety of mobile form factors, simulating user agent, and even rotating the device.
Multilingual Improvements
Global areas and stacks are now multilingual: if you have multiple language areas in your site, stacks and global areas you add will have separate instances for each language, and the appropriate stack contents will be displayed on the appropriate pages with no hacks.
You can scan a multilingual section for all links and references to multilingual pages, and if those pages exist outside the current tree, they will be remapped into the current tree. (i.e after you copy a multilingual tree, you can rescan its links so they don’t point to the original tree.)

Developer Updates
Big thanks to mlocati for delivering a completely new way to specify database XML, built off of the Doctrine DBAL library, including its types and functionality instead of ADODB’s AXMLS. Database XML now has support for foreign keys, comments and more. Doctrine XML is a composer package and can be used by third party projects as well. More information can be found at https://github.com/concrete5/doctrine-xml.
$view->action() now works for blocks in add and edit templates. This makes block AJAX routing much easier (simply reference $view->action(‘my_method’) in your block add/edit template, and implement action_my_method) in your block controller.
