When a new version comes out, the panel shows it on the updates page. Before installing, the engine makes a copy of the database and verifies the archive fingerprint, so a damaged or swapped file never gets installed.
New files are installed only when you click. If something goes wrong, the database copy sits right there, and you can go back without trying to remember what the site looked like before.
