Now that PHP 8.0 has been officially released, we’ve made it available for all environments on Kinsta alongside PHP 7.3 and 7.4. Previously, PHP 8.0 (RC1) was only available for staging environments to prevent incompatibility errors on production sites.

The latest version of PHP introduces a number of performance-boosting features like JIT compilation, Union Types 2.0, negative index arrays, and more. PHP 8.0 is the fastest version of PHP yet, so we recommend upgrading if your site is fully compatible with it.
