Any plans for update the config to Vagrant ~ 1.7 ?

Hi, I just downloaded Your repo, but after ./rethinkdb.sh command I got:

This Vagrant environment has specified that it requires the Vagrant
version to satisfy the following version requirements:

  ~> 1.5.0

You are running Vagrant 1.7.2, which does not satisfy
these requirements. Please change your Vagrant version or update
the Vagrantfile to allow this Vagrant version. However, be warned
that if the Vagrantfile has specified another version, it probably has
good reason to do so, and changing that may cause the environment to
not function properly.

I've updated the version requirement to allow support for 1.7 here:
