Yes there have been some changes. We pushed out some CSS updates to all grids across the site to make them consistently use CSS grids. Sadly, we no longer support having trailing items in a gird be centered with this change. In order to ensure consistency and ease of development for common UI elements across the site sometimes we have to make these types of changes. Thanks for understanding.
Regarding the font clipping, I’ll have to take a closer look. On quick inspection it appears that the particular font you have chosen is bugged as has the wrong line-height though. I’m not sure there’s anything we can do about that. It’s even broken on the Google Fonts website: https://fonts.google.com/specimen/Concert+One (Try highlighting text to see that it doesn’t cover the entire height of the text)
