In this release we’re updating PHP versions to 7.4.28, 8.0.16 and 8.1.3. This is to counter the new CVE-2021-21708, where a bug was found in the PHP function php_filter_float.

The changes in the new versions are covered in the PHP changelogs. Please refer to either the PHP 7.4.28 changelog, PHP 8.0.16 changelog or PHP 8.1.3 changelog for more detailed information.

All Hypernodes will be updated over the course of the week. If you want to update sooner than that, please contact our support team.
