Share Release Notes and Post-Install Instructions

Share details about what’s new and changed in a released unlocked package with your users.

Share details about what’s new and changed in an unlocked package with your users. You can specify a release notes URL to display on the package detail page in the user’s org. And you can share instructions about using your package by specifying a post install URL. The release notes and post install URLs display on the Installed Packages page in Setup, after a successful package installation. For users who install packages using an installation URL, the package installer page displays a link to release notes. And users are redirected to your post install URL following a successful package installation or upgrade.

Specify the postInstallUrl and releaseNotesUrl attributes in the packageDirectories section for the package.
