print 7.x-2.2

This release fixes a few important bugs introduced in 7.x-2.1, regarding PDF, EPUB and by-email functionality, and some other long-standing bugs.

The 2.0 release marks the completion of the main objectives of the 7.x-2.x branch:

• Refactoring of all the link handling code to a separate sub-module: print_ui (if you don't enable this module, you will still be able to acess the printer-friendly pages directly at their URLs, but you won't get any module-generated links)
• Removal of the print array and of all hard-coded HTML code that was used in the old print.tpl.php to a print.tpl.php that is more inline with a normal Drupal template and to some themeable functions.
• Creation of a pluggable system for the print_pdf module, that can be used to easily add more PDF libraries.
• Refactoring of the dompdf, tcpdf and wkhtmltopdf to separate sub-modules (print_pdf_dompdf, print_pdf_tcpdf and print_pdf_wkhtmltopdf).
• Creation of the print_pdf_mpdf module which generates PDfs using the mPDF library.
• Creation of a new export format (EPUB) using the new print_epub module, which uses the PHPePub library to create EPUB files. Support for EPUB libraries is also pluggable, and PHPePub is handled in the new print_epub_phpepub sub-module.

Word of caution:

• The new template differs radically from the previous one. If you had custom print templates, you'll probably need to re-write them.
• The node visibility settings was removed, as this is beter handled via the already existing node-specific settings. If you relied on that one, prior to upgrading the module make a list of the affected nodes. At the moment there's no database upgrade function to keep those settings.
• The module has changed some of the internal APIs.. If you were calling them directly, take a look at the new API documentation. Specifically, the PDF generation from HTML no longer takes a 'print' array as the first argument, using instead a much smaller 'meta' information array as the second argument.
• Most of the custom text replacement was removed.. Use of the "String Overrides" module for most of those is recommended.
• The print_mail pre and post hooks were removed for now. If they're replaced, they'll probably provide different capabilities.

Changes since 7.x-2.1:

• Code styling fixes.
• Filter scripts in dompdf only, since that is the vulnerable one.
