Docking/MDI for WPF and UWP has several new options that give you more control over UI appearance. Tab text on tabbed MDI tabs will now trim long text with ellipses in the middle, instead of the end, allowing for filenames to be more readable.
SyntaxEditor's completion and parameter info providers in all language add-ons now allow you to intercept OnSessionOpening, even when no items were pre-populated, so that you can add your own custom items/info. Cut, copy, paste, drag, and drop all now support the block and full line flags that are compatible with Visual Studio. The Python Language Add-on added a text range property to all type and function definitions, allowing you to implement features like go to definition easier.
The Shared Library added a new RingSpinner control that is an animated ring where the two ring segment ends chase each other around the circle. It's great for display while performing a lengthy operation.
All products received numerous other minor enhancements and bug fixes. See the announcement posts for the detailed list of enhancements and updates:
