macOS High Sierra Fixes

  • PDF export now remembers the auto expand checkbox state.
  • Gradients now restore transparent colors correctly.
  • Now syncing changes made to calendar event notes into figures.

Technical Improvements

  • Within its project files, Curio has long stored certain data items using Apple's NSArchiver encoder, which has been around since Mac OS X 10.0. However, Apple has mentioned they are deprecating this encoding class in favor of NSKeyedArchiver. So, in a future major Curio release, perhaps Curio 13, we will begin using NSKeyedArchiver when saving project data. With the Curio 11.4.4 release, Curio can now decode items stored with either encoder. Don’t worry, nothing has changed with data saving. We just added support for decoding a future format. This means Curio 11.4.4 can be used to open that future data format that eventually comes down the line (barring any other format changes, which we don't anticipate).
  • Several Evernote integration tweaks including NSKeyedArchiver support changes.
