In cPanel & WHM version 84, we updated the internal PHP from version 7.2 to 7.3. This document details the update and the status of known issues.

We tested the internal PHP's compatibility with packaged applications, such as phpMyAdmin. However, third-party plugin developers must verify that their applications function in the new version.
