Our approach to PHP version support

  1. For the TYPO3 versions we currently support, this extension will support all PHP versions officially supported by those TYPO3 versions.

  2. In addition, we are doing our best to support newer PHP versions as soon as they are available (even release candidates, alphas and betas).

  3. Before we mark a PHP version as supported via composer.json and ext_emconf.php, we ensure that all tests pass on that PHP version. (That also means that if you want to install the extension on that PHP version nonetheless, you will need to tweak Composer's platform settings to bypass this.)
