I have noticed some changes to the profiles of Math Stack Exchange like not displaying last seen information and how long you've been a member. I also really enjoyed the sizes of tags corresponding to the amount used, but it looks like that is now gone:

These are mine for example. Notice how they are all nice and neat as opposed to the more creative disproportionate tags. 

Another change is the questions on the front page of another user not having their related questions, but rather their top network questions which are unrelated to the site. Here is an example of a user’s *Mathematics Stack Exchange* profile front page having unrelated Stack Overflow questions:

Why did these changes happen? Please correct me and give me feedback!
