Hi,

The latest release 6.0.5 has builds for PHP 8.4
https://pecl.php.net/package/rdkafka/6.0.5/windows <https://pecl.php.net/package/rdkafka/6.0.5/windows>

PHP 8.5 builds will be added once 8.5.0 is released.

Thanks
Shivam
