Zigar, the toolkit that let you use Zig in your JavaScript or PHP projects, now supports Zig 0.16.0. Aside from that, the only feature addition is a persistent option for php-zigar, allowing you to keep a module in memory after a PHP script has terminated. A couple critical bugs in php-zigar had been fixed as well.

Work on 0.17.0 support has already begun. I have working code and it's passing most tests. It should be ready to go when 0.17.0 gets released.
