As always, updating your Server forgets the port numbers of your Event Servers, so if you happen to have more than one (as me), only one of those will start up properly. You have to manually reset those ports to non-conflicting ones to get all servers up. Ah well.

And static web publishing happily destroys the image files after the first run as it used to in previous versions, so this feature is still useless. Ah well.

Otherwise a pleasant experience (as long you do not open the Server Manager, because it's Non-UI will drive you crazy. Ah well.)
