Can confirm. In order to see the previews you have to right-click on the application icon and then click on 'All Windows' in order to see the window preview. Previously the previews would be shown when left clicking on the application icon.

The latest version of Dash to Dock released on 17th October retains the expected functionality so an issue specific to Ubuntu Dock.
