WooCommerce 7.1.0 was released this past Tuesday, November 8. The release package included an inadvertent change that bumped the required PHP version to PHP 7.4. In the past, we’ve communicated in advance whenever we’ve modified the PHP requirement for WooCommerce, and it is our intention to continue doing so moving forward.
We’ve updated the package, which can be downloaded directly from WordPress.org, to correct this issue. If you’re running PHP 7.2 or PHP 7.3, the updated package is now compatible with your PHP version.
If you’re running PHP 7.4 or newer, no action is required on your part.
While we’re currently continuing to support PHP 7.2 and up, we strongly urge you use PHP 8.0 or newer. PHP 7.4, while still receiving security updates, will only receive security support through November 28.
