Out of roughly 140 known downloads of #MediLog on day 1, one user reported a crash during startup. Because 1 is too many and I can't predict who else might run into this issue, here's v3.4.1
### New
- Nothing
### Fixed/Changed
- Fixed a crash during launch due to a setting which for some reason held an unexpected value
- Temperature: Custom name/logo were missing in certain places

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.
You can get it from here: https://cloud.zell-mbc.com/s/medilogDownload

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""
