As we get closer to a Commons 3.3 release, we're looking for folks to help test upgrades from Commons 7.x-3.2 to the upcoming 3.3 release. You can test using the nightly development snapshot of Commons. Make sure to see the upgrade steps referenced in that node, and please file issues in the Commons queue.
Thanks!
