Smile has released PDFpen and PDFpenPro 10.0, an update of its PDF editing tool for the Mac. It allows users to add signatures, text, and images, make changes and correct typos, OCR scanned docs, fill out forms, and more. 

You can mark up documents with highlighting, underscoring and strikethrough. Version 10.0 introduces watermarks, headers & footers, and, for Pro users, batch Optical Character Recognition.

Family Pack licenses, which cover up to five computers in one household, are $94.95 for PDFpen and $149.95 for PDFpenPro. Office Pack licenses start at $224.95 for PDFpen (five users) and $349.95 for PDFpenPro (five users). Demos are available for download (https://smilesoftware.com/PDFpen).
