Version 3.6.1 of the Mac edition has been released. A customer reported a crash; after some investigation, it turns out that the last couple of versions of macOS (after 14.2.1) contained a change (made by Apple) which reacted badly to some code in TimeStory. You would only have seen this crash if you ran TimeStory 3.6 on macOS 14.3 or newer, and your document contained sections, and certain other conditions were met, and it appears not to have affected most users.
