SmileOnMyMac has updated PDFPen (http://www.smileonmymac.com/PDFpen/download.html), its PDF editing and form-filling tool for Mac OS X, to version 5.6.

The update adds a setting for the name used with PDF notes and comments, as well as support for anonymous notes and comments. A new viewing preferences allows a PDF document to be viewed on screen at its physical size. Other improvements and fixes have also been made.

The changes in PDFpen 5.6 have also been made in PDFpenPro 5.6, the pro version that can also convert websites into PDFs, create fillable PDF forms, and construct document table of contents.

PDFpen costs US$59.95, and PDFpenPro is $99.95. Family pack licenses, which cover up to five computers in one household, are $74.95 for PDFpen and $129.95 for PDFpenPro. Upgrades from earlier versions of either application are $25, and free to users who purchased after Feb. 14, 2010. Upgrades from any version of PDFpen to PDFpenPro 5.0 are $40.

PDFpen 5.6 and PDFpen Pro 5.6 require Mac OS X 10.6 or later. Demo versions are available for download.
