How to change notification text

Using self-hosted unstable version on ubuntu server; e-mail notification system works, I get messages about individual and overdue tasks. But these are empty e-mails, no text at all, only a topic line.

Would it be possible to change this, for instance into something like the Vikunja Cloud messages? Somewhere I read that I had to recompile vikunja, but that is simply not doable for a non-coder like me. Via Config file?

This was a bug that I’ve fixed yesterday, please update.

OK now. Many thanks for the fast response!
