that you installed from the Unity Registry or a scoped registry, or from a local source. The information on this page also applies to packages you installed from the Asset Store, if they’re in the UPM format.

If you want to install a specific version of a package, install the package by name and follow its optional step to specify a version.

If you want to update packages that were installed from a Git URL, you can either re-install it as a Git dependency using a new revision or re-install it from the Unity Registry. For more information about how to specify revisions with Git dependenciesThe Package Manager retrieves Git dependencies from a Git repository directly rather than from a package registry. Git dependencies use a Git URL reference instead of a version, and there’s no guarantee about the package quality, stability, validity, or even whether the version stated in its package.json file respects Semantic Versioning rules with regards to officially published releases of this package.
