According to the documentation, new PHP versions should show up fairly quickly after release, but at the time of writing this the latest thecodingmachine/php:8.1-v4-slim-cli and thecodingmachine/php:8.1-v4-slim-fpm images are on PHP 8.1.1 and were last created on January 16th 2022. As far as I can tell all 8.1 images seem to be affected, not sure about other PHP versions.
Maybe building the images does somehow not work anymore since January 16th?
