Puppet 2.7 is waiting to get pushed to stable and I just wanted to give people a heads up
about the upgrade procedure. Please ensure that your master(s) get upgraded before your
agents. I'd recommend following this  guide. This upgrade is critical because 2.6
is no longer supported and doesn't receive security releases, leaving both masters and
agents potentially susceptible to attack.
Let me know if you've got any issues or questions.
