Hello,
PHP 8.0 is already only under security support, with 8.1 and 8.2 being actively supported. Being that our SDK and plugins deal with handling cryptocurrency, our new SDKs and plugins are going to follow officially supported language versions.
We are using PHPUnit 10 in our SDK, but we’ve confirmed that our tests will pass in PHPUnit 9. We’re updating our tests to run in both 9 and 10 in our workflow, and will rebuild our composer.lock file for PHP 8.0.
That said, if you just install the plugin, you should be OK on PHP 8.0 since there’s no need to run Composer unless you’re developing for the plugin.
We are working on making a few updates today in an effort to address the PHP 8.0 issue with Composer.
That said, please bear in mind that we will stop supporting PHP 8.0 on Nov 26, 2023 following its official EOL per https://www.php.net/supported-versions.php.
Thanks!
