- Modified widgets and complications in some sizes to reflect the "Show JD/MJD" (iOS/iPadOS) and "Display Item" (watchOS) preferences. As a side effect, these settings are reset to the default values upon the update of the app and you will have to set them again (sorry for the inconveniences). - Bug fixes and UI tweaks.
