So, could you remind us again of the various interactions of the
versions? (or is there a doc on it?)

Ie, of 2.6, 2.7, 3.0, which versions clients can talk to which versions
servers?

I'm not sure about 2.7 -> 3.0, but for the sake of this discussion perhaps what's important is that 2.6 clients and/or servers don't get along with 2.7 clients and/or servers. So any existing client or server using EPEL puppet will need to be updated at the same time.

Also, is there any changes people would need to make to their puppet
manifests between 2.6 and 2.7?

I think there are some small things here, but should mostly just work -- I'm able to share some (relatively simple) configs between 2.6 and 2.7 servers/clients with no issues. If someone could provide more detail than that, I'd appreciate it :)

In general I'm in favor of getting it updated...

+1, just hate the surprise breakage for those that don't see this coming...
