For Debian, hence "transitions". See the trackers


and notice 'curl' and 'r-base-3.5' at the bottom of the left column for
'planned transitions'.  Note also that they are independent -- as you noted
r-base "just" needs a rebuild.

But note that is Debian. I have no idea what Ubuntu but suspect something

We are muddying the waters a little with our inofficial repos. We are
generally trying not to break things but you never know...
