How to make a release

This is a reminder for myself, so I do not forget what needs to be done when making a release.

1. Version number

Update the version number in the file CMakeLists.txt, found in the top-level directory. The version number is found in the section "Project data".

2. What's new

In the file src/Librarian.cpp, update the text for "whatsnew". The content of this file will be shown to the user after an update.

3. Make release

Make a new release on GitHub.

4. Compile and upload

• Compile and upload APK/AAB to Google.

• Do a "ninja publish" this will upload the new version to flathub, and also upload the Qt sources to our own web site.
