Please, keep the warning about frontend updates before backend updates in mind

[chenger]

Hallo

I´ve running a small open-xchange system on debian but it´s growing up......

I want update to OX 7.81 actually I´ve running 7.8........
because I need this version for Office 2016 (oxtender) users.

In the OX update doku I can´t read this information...

How can I see which are the frontend patches and which one th backend updates.......

thans and regards

Stefan
