[Puppet Users] Check If State Changed with Puppet 0.25.4

We aren't using 0.25.x but we do use puppet reports to track puppetrun
status. We feed them into foreman, which should still support the
older puppet report format (pre-2.6.5), but you might also be able to
use puppet-dashboard. (Looks like it does support the older report
format: http://downloads.puppetlabs.com/docs/dashboardmanual.pdf.)
(The last_run_report should be in the same directory as state.yaml,
but you have to enable reports in your puppet.conf).

As an aside, the upgrade from 0.25.x to 2.6.x was relatively painless.

Perhaps someone else can address your question more directly?
