Marked 2.2 (811) is out as a free update for Marked 2 users (and available for download as a free trial). If you’re currently using Marked 2, just run Marked → Check for Updates to get the latest version.
A full changelog history is now available in the Marked Help. It will be updated automatically with each release. If you’ve missed an update or two and skipped ahead, it’s a good way to catch some of the finer details.
This particular release isn’t huge, but there’s some cool stuff (especially custom fonts for print/PDF headers and footers). If you make use of collapsed sections (Preferences, Window, “Headers Collapse Sections”), you’ll enjoy the ability to Command-click in the table of contents to collapse and expand sections on the fly.
The full release notes:
New stuff
Allow custom font for Print/PDF headers and footers
If “Headlines Collapse Sections” is enabled in Window preferences, holding the Command key while clicking an item in the Table of Contents will toggle the collapse for that section
