If no action is taken, sites using PHP 5.3 and 5.5 will be auto-upgraded to PHP 5.6 on February 25, 2025. Pantheon [currently recommends](/guides/php#supported-php-versions) at least PHP 8.1 for all production sites. + +Sites created with custom upstreams using EOL PHP versions may also have unexpected behavior upon site creation.
