[Pkg-puppet-devel] [release-notes] Any known issues with Puppet 2.7 -> 3.7 upgrade?

[Niels Thykier]

Dear Puppet maintainers,

I am currently updating the release notes for Jesse.  I noticed that for
Wheezy, we advised people to upgrade their master node before their
client nodes[1].

Do a similar thing apply for the 2.7 -> 3.7 upgrade, or are there any
other things people should be aware of before the upgrade (e.g. are
puppet 2.7 manifests compatible with 3.7)?
  If you have the time, I would strongly prefer you proposed the initial
wording of such a paragraph (if needed) as you most likely know the
issues better than I will.

Thank you in advance,
~Niels

PS: Please CC me on relies.
