The NEWS file has this (understated statement) to say about it:
* Various trailing-info sections are now preceded by a newline.

One of the benefits of having the blank line is that it makes it easier
to stop processing the list of changes before you get to the footer
data. For instance, imagine someone creating a directory with the name
"wrote 8 bytes read 4 bytes 4.00 bytes" and then putting a file named
"sec" in it. (Yes, the current code is vulnerable to someone putting a
newline into a filename, but we should really fix that in the same way
that ls does.)
So, this change does mean that any scripts that process the verbose
output will need to be tweaked to handle the new blank line. However, I
don't foresee any other changes being made to the verbose output (since
we are cognizant of the fact that people do parse it).
