New Features

New Twenty-One Client Area Theme

Just in time for the new year, the Twenty-One system theme gives the WHMCS Client Area a new look and feel. It includes Bootstrap 4, refined responsive behaviors, and many other distinct design elements.

Templating System

The Client Area is now even more customizable with an extensible, flexible templating system featuring inheritance through parent-child relationships and compatibility checking within the WHMCS interface.

System theme developers will be able to save time and effort both during initial development and when maintaining system themes.
