You will find that "Latest" is gone, and "Top" remains.

That's not true, at least for me. There are now tabs for "For you" (previously "Top") and "Following" (previously "Latest").

I can still see the "Latest" tab if I'm signed in, but can't if I'm signed out. Interesting.

No, "Top tweets" has become "For You" and "Latest" is now "Following"
