This update is all about the improved calendar support.


  • You can now use your system calendars (Birthdays, Vacations, etc.) to color the text or background of a day on a Posterino calendar object. Hover over a calendar object and open the popover available in the top right corner to set up this feature.
  • Added new calendar templates: “Square Images + Calendar”, “Vertical Months” and “Geek”.
  • Improved layout and features of the calendar object. E.g. you can now set individual fonts for different parts of the calendar via the Calendar inspector panel.
  • Added additional properties to format the calendar month and weekday.
  • Updated the online help to reflect the changes to the calendar system. I also added a topic on how to add personal events to a Posterino calendar.


  • The huge calendar inspector panel is now broken down to individual parts for Year, Months, Weekdays and Days.
  • Updated all calendar related templates.
  • Some minor user interface adjustments.


  • Handled some minor font substitution issues with the Geek and Windward templates.
  • Solved a problem where parts of a template seam to disappear due to inappropriate scaling of a Padding layer.
