Have they updated/changed the sliding windows?

[rippers]

I have noticed to my surprise the sliding side windows operate sooooo much better on my 2015 SE then they did on my previous 2013 Beach. They open and close very easily and seem a lot smoother.
I'm sure the older model had little foam strips along the bottom, the new one doesn't have them.
Not had it long enough (or had bad enough weather) to notice whether it leaks although our Beach didn't leak either.

Also noticed it has the updated roof and sliding rails.
