- Be sure to perform the 1.6.1 upgrade and migrations first before upgrading to 1.7.0. It will not work to upgrade directly from older versions.
- There are several gem updates, so be sure to run `bundle install` before running the new code. See using bundler with Wagn.
- It is recommended that you schedule downtime before this upgrade because the old permissions must be migrated into the new system using `rake db:migrate`.
