Here's a new beta of #MediLog v3.4.0, changes are mainly internal but substantial. Hence I would aprechiate if people would give it a spin.

Turns out there is (quite) a bit of code refactoring I need to do to make #MediLog more resiliant and easier to maintain. Due to this there may be new bugs creeping in which I will address as quickly as possible.
Therefore MediLog v3.3.11 fixes a few new bugs which got in with this one being the worst: "Fixed a regression which would always create the weight pdf document instead of whatever the active tab is""

Nothing big this time. #MediLog v3.3.10 fixes a bug which would sometimes require two clicks when switching between tabs as well as fixes a rare crash when starting a backup from within the settings screen.

And again some (minor) issues with the Glucose tab. I think I could do with an official tester for this tab. Volunteers welcome.
#MediLog v3.3.9 fixes…
- a crash when profiles table is empty. A situation I thought can never happen, but someone managed to :-/
- Glucose: Fixed a bug which would not immediately update the max value after a unit change
