We're working on a project for a client and intend to use the 4.10.0 release.  Since the release has been delayed for the last couple of weeks, we've been developing our templates/scripts against the nightly builds.  Everything seems to be working fine for us.

Our client wants to begin creating content this week, but since the release date has been moved to 9 November, we're unsure how to proceed.  Is there any danger in losing content if we install the latest nightly build, then upgrade it to the final build next week?  Also, what is that upgrade process?  Just replacing the files in the file system, while keeping our web.config intact?

Thanks -- and great work.... we're looking forward to the next release.
