That's a wrap from me. Other than the xmlrpc release, I started going through and modernizing the PHP in FillPDF 5.0.x. There's a lot I can do now (such as return types) now that I require a minimum of PHP 7.2. So I ran inspections on the whole module in PhpStorm and have been fixing the issues that make sense to fix (some are spurious).
Those in earlier timezones, enjoy the rest of the day!
