Preferred System Requirements
For the best performance of Gravity Forms, we recommend the latest production version of WordPress. Thus your Gravity Forms environment should utilize the same system requirements as WordPress itself.

Support Requirements
To receive support, we expect your Gravity Forms solution to be running the current or previous version of WordPress. For example, if WordPress 5.6 is the current version, then we offer support for environments running WP 5.6 and WP 5.5.
Refer to this 2013 blog post from our CEO for more context on this.
Older Environments
Gravity Forms may also work with some older versions of PHP and MySQL. Gravity Forms and official Gravity Forms Add-On new versions are not tested with with unsupported versions of those frameworks or WordPress. Additionally, older versions may expose your site to security vulnerabilities. See our article about the importance of updates.
Additionally, older versions may not meet the support requirements as listed above. If you reach out for support, you may be required to upgrade before you can gain assistance.
We highly recommend contacting your host to upgrade to the Preferred System Requirements..
PHP
If your PHP version is not listed on the php.net supported versions page you (or your web host) should update immediately.
