According to Subscribing to Email Notifications of Updates to Confluence Content, daily updates include deleted pages. This does not seem to be true, I do not get any in the daily reports.
I have checked the source code of Confluence 5.1.5, and the template that is used for the daily digest emails does not contain a reference to deleted pages (only created and updated), nor did I find any while digging about 5 levels of abstraction deeper.
I do receive deletion notifications when watching a space or page, but not in the digest mails.
Is there a way to also get them in the digest mails?
