Upgrade Process

WHMCS 8.0 and above requires PHP 7.2 or later. WHMCS 8.0 introduces support for PHP 7.4. Earlier versions of WHMCS do not support PHP 7.4.

You will only see the WHMCS 8 updates within the Automatic Updater if you are running on PHP 7.2 or later. If you are running PHP 7.1 or earlier, to update to WHMCS 8 via the Automatic Updater, you will first need to upgrade to PHP 7.2 or PHP 7.3, and then check for updates and perform the update.

Once you are running WHMCS 8, you can upgrade to PHP 7.4.

Automatic Updating

If you are running WHMCS 7.0 or later, you can use the built-in Automatic Update utility.

Go to Utilities > Update WHMCS to begin the process.

If the update was released recently, you may need to click Check for Updates before the update will be available.

For more information about updating, refer to the Automatic Updater documentation.

Client Area Home Page SSO

Clients can now use single sign-on (SSO) to access their active services directly from the main page of the Client Area Home Page. Due to this addition, it is now possible to create custom Client Area Home Page panels that span both columns of the desktop web browser page layout.

Custom Actions

In the WHMCS 8.5.0 RC 1 release, custom actions are available for use in provisioning modules. The CustomAction object lets developers define items that can perform actions and then redirect the user to a defined URI. Currently, you can use this to define a list of SSO items that will display on the Client Area Home Page.

You can now configure cross-selling to display recommendations when customers add a related item to the shopping cart. You can control recommendation locations, content, and appearance as well as individually configuring the recommendations to associate with each product.

Deprecation and Removal Notices

Removed Modules

Additionally, the third-party BuycPanel module has been deprecated and will not function in earlier versions of WHMCS. Upgrading to WHMCS 8.5 will remove the module and update any products that used it to use the Auto Release module instead.

ClientDelete Hook

We have deprecated the ClientDelete hook and recommend using the PreDeleteClient hook instead.
