Post-upgrade messages no longer being displayed
In 5.44 for example, the post-upgrade message looks like this:
Congratulations! Your upgrade was successful!
A token has been updated in the invoice template. Check the system checks page to see if any action is required.
Note that there is always at least the Congratulations! Your upgrade was successful!
that comes from https://github.com/civicrm/civicrm-core/blob/2eab44850a420083bafef133278b34f43d28cc70/CRM/Upgrade/Page/Upgrade.php#L139
In 5.47 for example you get nothing. This line is no longer TRUE: https://github.com/civicrm/civicrm-core/blob/2eab44850a420083bafef133278b34f43d28cc70/CRM/Upgrade/Page/Upgrade.php#L172
Doesn't affect cv
just the UI.
