New sites created on the platform now use PHP Runtime Generation 2.
PHP Runtime Generation 2 includes updated extensions, PHP 8.4 availability, and enhanced security features. This new PHP runtime will begin rolling out to existing sites on September 24.
Some PHP extensions and OS packages have not been ported over to Generation 2 yet, and may never be ported. Review the OS Packages and PHP Extensions documentation to review these changes. If your new sites depend on these, we recommend you downgrade to Generation 1 and contact your Customer Success Manager or create a support ticket to discuss your site needs.
