See failed builds here https://travis-ci.org/sensu/sensu-puppet/builds/172202862

Platform and version information

• Your OS:
• Your Ruby version: 1.8.7, 1.9.3, 2.0.0
• Your version of Puppet: 3.5 w/o future parser
• Your version of Sensu: 0.26
• Your version of this module: 6c927f6

Anything else to add that you think will be helpful?

I'm not sure if this project aims to follow semantic versioning, but based on the published support schedules for Puppet and Ruby, I believe its appropriate for this project to drop support for Puppet < 4.0 and Ruby < 2.0 in the next major version release. Although Puppet 4.0 supports Ruby 1.9.3 and 2.0, it is not tested on these versions of Ruby.

Although I am motivated to submit this issue by the failure of a particular pull request, I think this change makes sense going forward for the project as a whole. 😉

Yes, I think at this stage we've added multiple conditionals to travis just for ruby 1.8.7, and it's becoming arduous.

I think the next release (2.2.0) will be the last that supports ruby 1.8.7. Does that seem acceptable?

[cwjohnston]

Makes sense to me 👍

Also, in addition to this, support for puppet 3.8.7 is EOL at the end of the year, so no more puppet 3 either, which means we can finally start using some of the Puppet 4 goodness.
