This is a maintenance release for the 7.4 series of WHMCS that includes updates, bug fixes and usability improvements.
As communicated in last month's PHP 7.1 Status Update blog post, WHMCS v7.4.2 contains changes to the Automatic Updater that enables us to validate the ionCube Loader version requirement of future versions prior to allowing an update to occur. These enhancements will help ensure a smooth and trouble free update experience to the upcoming WHMCS 7.5 series. You can learn more about these changes and what necessitated them in the release notes.
