Version 2.6 was just released, with a focus on exporting timelines, particularly large ones.
The main new feature is the ability to export your timeline to a single-page PDF, producing high-quality output at any zoom level, with searchable text and functional hyperlinks. This is just an option on the same Export dialog that previously only supported PNG output. If you’re sending your timelines to non-TimeStory users, single-page PDF is now the best and recommended format in most cases, unless you specifically need PNG image output, or a paginated printout in PDF form via the Print window.
You can also now export just a specific date range, making it easy to break up a long timeline into slices.
There’s a little more info on the Release Notes page. 2.6 is live in the App Store; check it out!
