+## urlwatch
+
+This version configures the regular execution of `urlwatch` to find differences in flohmarkts user database.
+
+The job is called from /etc/cron.hourly/ every hour.
+
+If `urlwatch` finds a difference in the user database stored in CouchDB for a flohmarkt instance it'll send an email to the administrator.
+
+## new setting "admin_mail"
+
+The email address of the administrator is stored inside a new setting admin_mail. The upgrade will guess a default:
+
+* it'll try to read the email of the flohmarkt admin from couchdb
+* if it fails for some reason it'll use 'admin@<your main domain>'
+
+You'll get WARNINGs during the upgrade if the default has been guessed for your settings.
+
+If you do not like the default you can change it from the command line like this:
+
+```sh
+yunohost app setting <my flohmarkt app id> admin_mail -v <email to send change notification to>
+```
+
+You can find `<my flohmarkt app id>` by executing `yunohost app list` and looking for the blocks containing `name: flohmarkt`. The line `id:` contains the `<my flohmarkt app id>` you're looking for.
+
+Usually this will be `flohmarkt`.
