Our project's overview page used to list the author of each commit that went into our repo, but now it lists instead the user who pushed the commit. Unfortunately for us, those aren't the same person, and the pusher is kind of useless.
Right now we're checking in to SVN and then using git-svn to sync to bitbucket (as part of our svn --> git migration). The script that pushes to bitbucket runs as one of our users, so all pushes come from the same person, even though they are authored by many different people.
I can understand why you want to be precise about identifying who pushed the commit in the overview feed, but that's not useful info for us. Can we at least have an option to show the author instead, as the overview used to?
