Cron.php not showing changes to files

I recently upgraded to v23 and I have a Crontab which runs cron.php every 5 minutes. Up until the upgrade, this would send me notifications for any file additions, deletions, etc. The cron log shows that the command is running but I get no notifications. Is there a setting in v23 that I’ve missed to get the notifications?

Are the notifications triggered by cron.php working in v23 for anyone?

Still hoping to hear from someone who can either confirm that email activity notifications are not working in v23 or that they are and, if so, why I am not able to get them to work.
