Tableau 10.4 was released this week, bringing with it a bunch of great new features.
See the full list of features here: https://www.tableau.com/products/new-features
Some of my favourites, that I think most customers will appreciate, include:
Backwards compatibility (old versions of Desktop can publish to 10.4)
Improvements in how dashboards look
Australian map enhancements
Increased functionality in the web browser authoring
Real time conversations in Tableau Server
