We have now released Prince 12.3, a maintenance release with improvements and bug fixes:

• Improved performance of tagged PDF for large documents.
• Support prince-pdf-page-layout: two-page as an alias for two-page-left.
• Fixed bug where opacity on an element could affect following filters.
• Fixed bug where the overflow property incorrectly applied to table rows.

We encourage all customers using Prince 12 to upgrade. Thank you to everyone who has provided comments and feedback on Prince!
