Latest changes?

Ok - I'm getting a different view from yesterday - more wasted white space on either side of the planner view which means I can't see the whole week without scrolling.  The previous days do collapse but it means now I have to click on them to open them up and scroll to get a view of the week regardless if the days have past or in the future.  I also am getting an "All" team view it seems of my events instead of being able to filter on the team and the calendar events tied to that team .... I've wasted an hour at least in trying to figure out what has changed .... is there a change log posted somewhere ...?????
