Hi Becket, Did you mean this to be an official [VOTE] thread? If so, it may be a good idea to start a new thread with the appropriate title and link to this one. It would be good to agree on this relatively soon so that we can update JIRA, the wiki and anywhere in the code and documentation where we reference the version number.
