It appears that today Stack Exchange has changed the appearance of the MathOverflow front page. It now looks more similar to Stack Overflow. The most noticeable change is that the counts of answers, votes, and views to the left of each question has been condensed. I don't know how long Stack Overflow has looked similar to this.
It's especially unfortunate because just last week we introduced changes to make viewing reputation on the site become opt-in. These changes appear to be completely broken by today's changes. I'm disappointed that nobody at Stack Exchange thought to mention these imminent changes to us as we seek to implement the reputation opt-in feature.
The last time I noticed such a large change in the appearance, there had been months of announcements on the network-wide meta leading up to the changes, but I can't find anything similar this time.
Question 1: Were these changes announced at all before they went live?
Question 2: What is the scope of the changes? I've noticed two things:
The numbers next to a question display differently, as mentioned above.
The script which hides reputation is broken.
Are there other changes I'm missing?
Question 3: Are there more changes on the horizon?
Question 4: What is the context of these changes? Is this a continuation of the "new site themes" evolution?
