Schmitz Smile has issued version 9.1 of [1]PDFpen and [2]PDFpenPro, enhancing the PDF editing apps that received a major bump to version 9 earlier this year (see '[3]PDFpen 9 Improves Markup, Tables of Contents, and More,' 13 April 2017). The releases now enable you to add and remove Bookmarks, which will appear at the top of the Table of Contents (Michael Cohen provides more details on this addition at the [4]Take Control Blog). They also now open previously opened documents at the same size and position, and resolve potential memory leaks. Upgrades from version 8 of either app cost $30, and the upgrade price from PDFpen to PDFpenPro is $50. Those who purchased the previous version on or after 1 January 2017 can upgrade to the latest version for free.
