Version 1.6 was released on November 19. Full release notes here. You’ll see some great new features along with several bug fixes.
The biggest change in this release was the addition of auto-updating “today” values for dates. Set a span event to end on “=today”, and it will always show up as ending on the current date, whatever it is.
The second biggest change, although less visible, is that you can now specify “Automatic” as the text color for any section or event. Just like the Date Labels previously did, this causes them to automatically choose white or black, depending on their background.
