I built a module using php/php-windows-builder (example), but when I try to use it with PHP 8.5.0RC1 (downloaded from https://windows.php.net/qa/), I get the following
Module compiled with module API=20250926
PHP compiled with module API=20250925
It is my understanding that 20250926 API refers to the newly cut master, and 20250925 is the API for the 8.5.0RC1, so my guess is php/php-windows-builder is using master to build modules, rather than 8.5.* series.
