Our team just did a big effort to get from 11 to 12. After that the effort was quite minimal. Some little gotchas re: providers in 13 but we're just today finished the 14 upgrade and will probably let 15 marinate until we upgrade to that.
I think we're dealing with the providers now as we get warnings on 0.12.29 that they'll be deprecated in 13 so nice to know that we're over the biggest hill.
I'm trying looking to get some feedback on my ruby gem that allows you to post events to graphite from a capistrano deployment. I'm pretty new to Ruby and am looking for any critiques or suggestions or even just a "hey, I use that!" Thanks in advance.
