SmileOnMyMac has released version 2.2.1 of PDFpen and PDFpen Pro, the latest update to its PDF-editing and form-filling utility. This release adds PDF Workflow to “Open with PDFpen” directly from the print dialog, improved compatibility with off-spec PDF files, and minor bug fixes. PDFpen Pro has the same features as PDFpen, as well as the ability to create new PDF forms. PDFpen is priced at US$49.95, while PDFpen Pro costs $94.95. Both require Mac OS X 10.2.5 or later and have 30-day demo versions available.
