6.0.0

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.

BREAKING CHANGES

• New minimum requirements PHP7.3+, WordPress 5.3+, Gravity Forms 2.5+
• Removed Gravity PDF v3 template stylesheet (swap legacy PDF template to Focus Gravity template)
• Removed Gravity PDF v3 to v4 migration code (upgrade to v4/v5 before attempting v6 upgrade)
• (Dev) Moved all vendor (Packagist) packages to new GFPDF_Vendor/ namespace (BC aliasing for common classes included). Prevents all vendor conflicts with other plugins.
• (Dev) Removed “Setup Custom Templates” tool (manually copy over template files to PDF Working Directory)

• (Dev) Changed the first parameter $font_name in GPDFAPI::delete_pdf_font() to $font_id instead. You can no longer delete the font by
  its name, as it is no longer a unique identifier.
• (Dev) Majority of admin user interface markup (UI) changed to suit new GF2.5 UI ()
• (Dev) Renamed \GFPDF\Helper\Fields\Field_CreditCard class to Field_Creditcard
• (Dev) Change \GFPDF\Model\Model_Install __construct signature by removing Helper_Abstract_Forms dependancy from the start and adding Model_Uninstall at the end

• (Dev) Adjusted ID from #tab_pdf to #tab_PDF for container on Global PDF settings page. This ensures both the Global and Form PDF settings use a consistent ID.
