Smile has updated both PDFpen and PDFpenPro to version 5.9, which improves overall performance by reducing memory usage and adds the OAuth secure authorization method for those using PDFpen’s Save to Evernote capability. Additionally, both editions now use Apple’s sandboxing for improved security and compatibility with the Mac App Store, though neither PDFpen nor PDFpenPro has been updated to version 5.9 in the Mac App Store as of this writing.
