Limits worth knowing in Merkuro Calendar

  • Stable releases are for Linux. The Windows builds on KDE's site are nightly installers that KDE labels unstable and intended for testing.
  • It depends on Akonadi and KDE PIM packages; without kdepim-runtime, the project says the calendar component is heavily restricted.
  • The Kontact Flatpak that includes Merkuro lacks some desktop integration, such as the calendar applet plugin, so KDE recommends a distribution package.
  • Proton Calendar cannot be connected, and services with non-standard calendars or task lists, such as Todoist, are not supported.
