PDFpen and PDFpenPro 8.1
Smile has pushed out version 8.1 of PDFpen and PDFpenPro, which adds visible snap-to guides that help you more precisely place images, shapes, text boxes, and other objects. The PDF editing apps now display an email address for a self-signed certificate (instead of the issuer), retain size-to-fit font in appearance for form fields, resolve a hang when performing a Save As for forms with required fields, work around a drag-and-drop issue in the sidebar in macOS 10.12 Sierra, and avoid converting grayscale images to RGB after opening. ($74.95/$124.95 new with a 20 percent discount for TidBITS members, $30 upgrade, free update from version 8.0, 70.3/71 MB, release notes, 10.10+)
