Enable the Enable Pre-release Packages setting to display pre-release packages in the Package Manager window. Pre-release packages appear with the tag in the list view and the tag in the details view, as a reminder of which packages will be released with the LTS version of the Editor.
By default this setting is disabled because pre-release packages are still being verified as stable enough for production, but are not fully released yet. For more information about the lifecycle of packages, see Package states and lifecycle.
Enable the Show Dependencies setting to:
Show any packages that are installed as indirect dependenciesAn indirect, or transitive dependency occurs when your project requests a package which itself “depends on” another package. For example, if your project depends on the email@example.com package which in turn depends on the firstname.lastname@example.org package, then your project has an direct dependency on Alembic and an indirect dependency on Timeline. More info See in Glossary in the Package Manager window’s list of packages.
Display a package’s dependency information in the package’s details on the Package Manager window. This includes the following:
Is using lists any packages that this package requires, including the specific version.
Used by lists the names and versions of any other packages that depend on this one.
Note: By default, this setting is disabled. For more information about how dependencies work with packages, see Dependency and resolution.
The Scoped Registries group displays a list of scoped registries already added to the current project on the left, and the details of the selected registry on the right.
For detailed information about scoped registries, including how to use and configure them with the Unity Package Manager, see the documentation on Scoped Registries.
Note: If you added a scoped registry but you don’t see it in the My Registries context or the My Registries context isn’t available at all, it might be because the package registry server you added does not implement the /-/v1/search or /-/all endpoints, which means that it is not compatible with Unity’s Package Manager.
Adding a new registry
To add a new scoped registry to your project:
Select the + button at the bottom of the list. A new entry appears as New Scoped Registry in the list and blank values for the details on the right and the Revert and Apply buttons change to Cancel and Save buttons.
