Due to popular demand I started working on making the Diary icons more flexible:
- unlimited number of emojis
- ability to add, delete and change emojis to whatever you like
- Introduction of emoji templates. Smiley and weather below. I am open to ideas

And yet again a new #MediLog release. Despite the version jump to v3.5.0 this is still a rather small, bug fix release.
The big news however is a new F-Droid flavour of MediLog to allow F-Droid to create reproducible builds which will be the recommended flavour for all F-Droid users going forward.
Reproducible builds is an important but rather technical topic which I try to explain here: https://codeberg.org/toz/MediLog/wiki/Reproducible-Builds

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
