This has been already suggested in 2010.
I've been using XenForo since 2012 and I've already lost count of how many times I had to login to customer area, download the upgrade package, upload the package and finally run /install. In 2012 this procedure was "ok" but in 2018 it is a missing...
I sent a resource and then updated 3 times. Now I want to remove latest update, and then last update will be download able again from download button.
How can I do that? I can remove last updates, but removing newest update is not possible.
