Important Note
  1. The update is expected to be available in all regions within the next few days. The actual time of release may vary slightly depending on the region.
  2. The update will set the default map source for Synology Calendar as "None (plain text)". This will not affect existing events. If you wish to continue using a third-party service to open maps, go to "Settings" > "General" and change the "Map source for event location".
Fixed Issues
  1. Fixed multiple security vulnerabilities. (Synology-SA-21:12)

  3. Fixed an issue where users might still receive notifications even though notification settings have been turned off.
  4. Fixed an issue where users might not be able to import ICS files to shared calendars.
  5. Fixed an issue where events with custom time zones might not be displayed when they are imported via ICS files.
  6. Fixed an issue where new users might not be able to create non-all-day events when the time zone has been modified in Control Panel.
  7. Fixed an issue where users might not be able to delete newly created events when syncing Synology Calendar via the Outlook CalDav Synchronizer plugin.
  8. Fixed an issue where syncing Synology Calendar on macOS might fail.
  9. Fixed an issue where users might not be able to invite other Active Directory users via eM Client.
