 * drop support for the unmaintained payment font (`pf`) for use in font-based icons
 * refactor formatted text transform to simplify how inner space is collapsed; verify only inner hard breaks are preserved
 * allow relative font size for sub and sup to be set independently; support combined setting for backwards compatibility
+* upgrade prawn-svg to 0.36 to fix dependencies, improve gradient support, and support additional properties; disable experimental warnings when requiring prawn-svg on Ruby 2.7 (#2551)
