The vertical alignment of grid cells is now middle, rather than top. Is this a conscious change?
For grids where each cell only contains a single line of text this makes it a bit easier to line it up with a custom row height. However, in most cases where I've customized the row height I've got multiple lines of text and for those it looks a bit silly.
Might be worth mentioning in the release notes, possibly including an example of how to put it back the way it was.
