Trying to semi-automate my upgrade process by using "drush civicrm-upgrade", but I'm concerned that any critical messages, e.g. that default message templates have changed, won't be displayed in the shell.
I have a vague recollection that there exists a URL which will display the site's most recent upgrade messages, but I can't find it now in the documentation. Is there such a URL?
And does drush civicrm-upgrade display such messages in the shell?
