New
Export Presets – You can now define Export presets, containing multiple scales and filetypes to be applied to slices and exportable layers with a single click.
Touch Bar Support – Sketch supports Touch Bar on the new MacBook Pro – allowing you to quickly access tools and features straight from the keyboard.

Improved
The maximum zoom level has been increased four times to 25600% to allow more precise pixel work
During vector editing, clicking the first point will now close the path
Slice layers can now be hidden along with any other layer type
Sub-paths can now be hidden and are thereby excluded from boolean operations
Multiple corner radii for rounded rectangles should now be specified using the semi-colon separator, not the backslash. Because of this, the corner radius text field now supports math functions as well
You can now select multiple Pages at the same time to delete them
We’ve updated our About window with a brand new look
The Flip controls now show an active state when a layer has been flipped horizontally or vertically
The Save as Template dialog now pre-fills with the document’s name
Holding the Option key in the vector editor no longer hides all points
When dragging a vector handle control point, you can now hold Shift to lock it to the direction of the opposite control point
A path consisting of only two points will add points to the start of the line when the first point is selected
The menu for swapping Symbol instances now respects the same grouping and sub-menus that appear under Insert › Symbol
Reduces memory usage while using Mirror
The File › New From Template menu has been restored
Improves performance when combining many non-overlapping shapes
Improves performance when editing Symbol instances in large documents with many (nested) Symbols
