There are essentially two variations of a release; Internal and External. Releases can be internal to signed in project users, or public to the world.
💡 Tip: Default visibility on Releases are set to Private
Not every release is meant to be publicly accessible. There may be the case where there is sensitive information on a release, or simply an update to an internal process that doesn't affect your customers.
Internal Releases are locked down by design to give specific project users a private, collaborative platform as they are only accessible by logging into your LaunchNotes project.
Public releases are used when you have a customer facing change that everyone should know about.
Public release allow you to post public updates to external audiences, and are shown on your hosted LaunchNotes page. You can still make internal updates that are only seen by internal signed in users.
