Hi Seb,
no more spacing, no 
, this is part of the upstream changes I was talking about. Padding is configurable now, Adwaita will keep its own values and Yaru will use the smaller one.
About testing, I need to double check whether PPA is still valid (latest build is from 13 hours ago, at the time of writing, so it might), otherwise I believe building from master is the only way so far.
EDIT:
Eoan is the target yes, if we’re still on time for it of course
Here are some screenshots
