derickr, 
🎉 I've just released @Xdebug 3.3.0alpha2, with preliminary support for PHP 8.3.
🔗 https://xdebug.org/announcements/2023-09-06
:xdebug: It also adds some functionality to xdebug_get_function_stack(), more about that later!
🐛 Uploading it to PECL didn't work, as due to an upgrade, MySQL now (finally) rejects characters that the table charset wouldn't allow, instead of just corrupting it. That took two hours to debug and fix. PECL will warn now → https://github.com/php/web-pecl/commit/cf57e9370820fa7738c782a751b47de713e0c3be
