If the person setting this up is different than the person working day to day on the project it's easy for upgrades to get missed.
One approach could be to add a version check to the push hook that happens on a monthly interval. If a new version is available the push gets rejected with an informative message. Since it would only happen once a month, if upgrading at that time isn't desired the push can just be repeated. This seems like a fairly small decrease in ergonomics for keeping people upto date. Likely to be other solutions.
