+__NOTE__: This module is no longer commercially supported in Silverstripe CMS 5 and it does not provide a CMS5-compatible version. The parent library is outdated and there are better alternatives like [UndefinedOffset/silverstripe-nocaptcha](https://packagist.org/packages/undefinedoffset/silverstripe-nocaptcha).
