Metadata.db download works again removed DEVELOPMENT constant removed db logging in debug mode (too, noisy, to less information) code refactoring url_for_other_page feed languge set to en-EN update status shos local time instead of UTC Error handling (back to index page) in case of gdrive authenticate aborted Mistyping page register fixed Mistyping bokk fixed Added uploaded books to tasklist (#442) Error handling for failed file update added Code refactoring worker thread Tasks now never show any decimal values Converter function unified removed shell from subprocess call preparation for limiting domain for registering emails Book series can now increased in 0.1 steps (#562) Accordion panels in config are now usable on touch devices like iPad (#545) Gdrive authenticate button only visible after logged in (#525) Fixed misstyping in german translation
