That's a question only you can answer, but asking about "what about X release" is fruitless because of a complete lack of ABI support. In six month's it's an obsolete question, whose only two answers are "be the developer and watching the changelog" or "compile the module, test it, and pray to the diety of your choice that it doesn't explode".

Certainly ;) I'm unfamiliar with Varnish's lifecycle. Just pointing out what should be noted (frankly, with the last few years of releases, unless there's a specific feature or bug you need to overcome, upgrading nginx to "latest" doesn't offer much value. I would love to be proved wrong here though ;) ).
