We have a migration section of the YP reference manual [1], which is linked
from the release notes. I strongly recommend reading this on every major
release upgrade, as it should cover changes that you need to adapt your
recipes/configuration to.

That said, there are some limitations of this currently:

1) We (and I say "we", it's often me supplying Scott with the information)
usually only get to writing it towards the end of the release cycle, so if
you're following master then you won't get much out of this, but then again if
you're following master you should probably expect to have to deal with
the bleeding edge. There is a wiki page [2] where we are supposed to be
adding items as we go along during the cycle, and we did do a few during
2.3 but there were still quite a number of things that were missing and
lots of details that needed to be added.

2) There may be upstream changes that we pick up as a result of recipe
upgrades that could cause issues for someone (depending on what you're
actually building, of course). We don't really have a way of easily tracking
these at the moment; unfortunately every upstream reports their changes
differently.

Cheers,
Paul
