This major release is designed specifically for Gravity Forms 2.5+ and includes breaking pages that may affect you. You are strongly encouraged to review the upgrade guide before attempting to update to v6.

Acts like GPDFAPI::get_form_pdfs( $form_id ) but filters out any PDFs that don't pass conditional logic checks for the current entry. * Added Helper_Abstract_Config_Settings class which template config files can extend to automatically have the current PDF settings injected into the class. * Adjusted some logged items to use less severe alerts (when template config file doesn't exist, and when native PDF support for a field doesn't exist) * Upgrade vendor packages to latest versions * Remove all backbone.js and underscore.js Font Manager code from Gravity PDF admin pages * Remove gulp as dependency (build is done using only webpack now) * Add better error log messages for PDF Merge tag processing * Pass additional information to the gfpdf_field_container_class filter

• Enhancement - Added deployment code switch so the template redeployment feature can be turned on and off. This release doesn't require redeployment.
• Enhancement - PDF_Generator() variables were getting long and complex so the third variable is now an array which will pass all the optional arguments. The new 1.7 compatible functions.php code includes this method by default. For backwards compatibility the function will still work with the variable structure prior to 2.2.0.
• Bug - Fixed error generated by legacy code in the function PDF_processing() which is located in render_to_pdf.php.
• Bug - Images and stylesheets will now try and be accessed with a local path instead of a URL. It fixes problem where some hosts were preventing read access from a URL. No template changes are required.

• Bug - Fixed HTML error which caused list items to distort on PDF

• DOMPDF - We updated to the latest version of DOMPDF - DOMPDF 0.6.0 beta 3.
• DOMPDF - We've enabled font subsetting by default which should help limit the increased PDF size when using DejaVu Sans (or any other font).

• Bug - Fixed mb_string error in the updated DOMPDF package.

• Bug - Fixed issue that caused website to become unresponsive when Gravity Forms was disabled or upgraded
• Bug - New HTML fields weren't being displayed in $form_data array
• Feature - Options for default templates to disable HTML fields or empty fields (or both)

• Backwards Compatibility - While PHP 5.3 has was released a number of years ago it seems a number of hosts do not currently offer this version to their clients. In the interest of backwards compatibility we've re-written the plugin to again work with PHP 5+.
• Signature / Image Display Bug - All URLs have been converted to a path so images should now display correctly in PDF.

• Feature - Added defaults to configuration.php which allows users to define the default PDF settings for all Gravity Forms. See the installation and configuration documentation for more details.
• Feature - Added three new configuration options 'default-show-html', 'default-show-empty' and 'default-show-page-names' which allow different display options to the three default templates. See the installation and configuration documentation for more details.
• Feature - Added filter hooks 'gfpdfe_pdf_name' and 'gfpdfe_template' which allows developers to further modify a PDF name and template file, respectively, outside of the configuration.php. This is useful if you have a special case naming convention based on user input. See http://gravityformspdfextended.com/filters-and-hooks/ for more details about using these filters.
• Feature - Custom font support. Any .ttf font file added to the PDF_EXTENDED_TEMPLATE/fonts/ folder will be automatically installed once the plugin has been initialised. Users also have the option to just initialise the fonts via the settings page. See the font/language documentation for details.
• Compatability - Use Gravity Forms get_upload_root() and get_upload_url_root() instead of hard coding the signature upload directory in pdf-entry-detail.php
• Compatability - Changed depreciated functions get_themes() and get_theme() to wp_get_theme() (added in Wordpress v3.4).
• Compatability - The plugin now needs to be initialised on fresh installation and upgrade. This allows us to use the WP_Filesystem API for file manipulation.
• Compatability - Automatic copying of PDF_EXTENDED_TEMPLATE folder on a theme change was removed in favour of a user prompt. This allows us to take advantage of the WP_Filesystem API.
• Compatability - Added Wordpress compatibility checker (minimum now 3.4 or higher).
• Bug - Removed ZipArchive in favour of Wordpress's WP_Filesystem API unzip_file() command. Some users reported the plugin would stop their entire website working if this extension wasn't installed.
• Bug - Fixed Gravity Forms compatibility checker which wouldn't return the correct response.
• Bug - Fixed minor bug in pdf.php when using static call 'self' in add_filter hook. Changed to class name.
• Bug - Removed PHP notice about $even variable not being defined in pdf-entry-detail.php
• Bug - Prevent code from continuing to excecute after sending header redirect.

• Bug - Users whose server only supports FTP file manipulation using the WP_Filesystem API moved the files into the wrong directory due to FTP usually being rooted to the Wordpress home directory. To fix this the plugin attempts to determine the FTP directory, otherwise assumes it is the WP base directory.
• Bug - Initialisation error message was being called but the success message was also showing.

• Feature - Added list array, file path, form ID and lead ID to $form_data array in custom templates
• Bug - Fixed initialisation prompt issue when updating plugin

• Bug - Fixed issue with product dropdown and radio button data showing the value instead of the name field.

• Feature - Added a Support tab to the settings page which allows users to securely (over HTTPS) submit a support ticket to the Gravity Form PDF Extended support desk
