# 3.7.4 (unreleased) * [Minor update to support PHP 7.4](https://github.com/silverstripe/silverstripe-framework/pull/9110) ## Running SilverStripe 3.7 on PHP 7.4 SilverStripe's standard test tools require `phpunit/phpunit-mock-objects` to run. This package has been deprecated and doesn't support PHP 7.4. SilverStripe is using a fork for its own PHP 7.3 unit tests: `sminnee/phpunit-mock-objects`. You can use this fork for your own project by running this command: ```bash composer require --dev sminnee/phpunit-mock-objects:^3.4.7 ``` This fork is not a supported module and SilverStripe does not commit to maintaining it.
