The biggest news would be the inclusion of the Dynamo player. This is a brand new tool located right next to the Dynamo icon on the manage pane focused on being a "player" for all your dynamo scripts:
Since the majority of Revit users in any firm is still not very proficient in Dynamo, this means that they can use the scripts that others have created without the hassle of opening dynamo. Awesome!
Comparable to Dyno: http://dyno.arcprojects.ru/ but a cleaner user interface in my opinion:
Pretty basic. Set script folder, refresh, filter functionality and PLAY! :) You can also edit the scripts by hitting the pen icon and Dynamo will open
But, because there is a but, it only works for scripts with OOTB nodes.The script can't contain any custom packages. On the few test I've done it doesn't seem to work even when the user have these packages installed on their computer, unfortunately.
Still, with a bit of converting and copy/paste you can create scripts with user input as well. The little script below number elements based on a spline running through them. The functionality in the Python scripts below is copied from the Springs and Clockwork packages.
