Today we have released Prince 17 with some major new features:

• Fragmented CSS grid layout, spanning multiple pages
• CSS cascade layers and nested CSS
• Markdown documents as input files
• JavaScript ES6 classes and a faster JavaScript parser
• OpenType COLR fonts, such as Segoe UI Emoji

The full list of changes and improvements can be found in the release notes and Prince for Books is now synchronised with Prince releases.
