So this has been talked about for a while and we have attempted to
gauge the 3/4 over the last year or so.  Unfortunately with the
upstream modules also dropping 3 support, we're kind of stuck
following their lead. We recently got nailed when the puppetlabs-ntp
module finally became puppet 3 incompatible and we had to finally pin
to an older version.  That being said we can try and hold off any
possible incompatibilities in our modules until either late in this
cycle or maybe until the start of the next cycle.  We will have
several milestone releases for Ocata that will still be puppet 3
compatible (one being next week) so that might be an option as well.
I understand the extra work this may cause which is why we're trying
to give as much advanced notice as possible.  In the current forecast
I don't see any work that will make our modules puppet 3 incompatible,
but we're also at the mercy of the community at large.  We will
definitely drop puppet 3 at the start of Pike if we manage to make it
through Ocata without any required changes.  I think it'll be more
evident early next year after the puppet 3 EOL finally hits.

Thanks,
