Upgrade Code Builder Managed Package
Usually, you don’t have to do anything to upgrade to the latest version of the Code Builder. When we release a new package version, we update your org automatically.
However, sometimes the push upgrade doesn’t work. If you don’t have the latest version, we recommend that you manually install the package through the Code Builder Setup page. From Setup, enter Code Builder in the Quick Find box, then select Code Builder. If a newer version doesn’t exist, the package installer informs you that you already have the latest version.
