Issue at #F-Droid is resolved. There will be a new #MediLog release v3.6.3 which is primarily a technical release for F-Droid. If you get MediLog from any other source there is no urgency to upgrade.Tooted on Thursday, 12 February 2026 10:36

New #MediLog release v3.6.2 is available as of now. As usual a few bug fixes and finally the long asked for feature to create a pdf of a chart so one can print or send it on.
For some reason F-Droid has not yet picked up the previous v3.6.0 release, let alone this one. Need to investigate

#MediLog v3.6.0 is available as of now. Aside from a few bug fixes this release introduces custom emojis / themes and support for changing the language for MediLog independently from the OS language.
v3.6.0 is also the release which will start moving off encrypted databases. If your db is encrypted v3.6.0 will automatically migrate to an unencrypted one upon first launch.
Ever since Android introduced default file system encryption the database encryption on top of the OS was mostly pointless. This change will significantly reduce app complexity for me and the size of the installation for you.
