If one is fine with Chalav Stam or Chalav Stam DE, then nothing changed. For people who won't use C"S equipment, then now any dish that touches milk might need further investigation.
Getting a cold brew, or an iced Espresso/latte drink should be fine still, as those items are either used cold/washed separately. Star-K recommended asking them to make the espresso in the paper cup. Hot plain espresso/Americano should be fine as well, as they only touch the espresso machines which aren't washed with trief.
Likewise, all other drinks that are hot have the same potential issues related to the equipment wash as they did before.
I think the only big thing that changed is the Star-K is no longer vouching for stores that they deemed "kosher friendly" regarding washing, or the actual kasharus on the syrups etc. But may of the syrups have visable OUs so shouldn't be a problem.
