Most of the changes won't matter to us because we use our own issue tracker and Wiki. However, one change will affect us all: the subversion repository URL will be changed. After the upgrade is complete, you will receive an e-mail with the new SVN url. It will probably be easiest for you to just check out a new working copy at that time.
