The Package Manager window displays the list of packages or Asset packages according to the criteria that you select by filtering, including, or searching:
(A) Select these expander icons to show and hide the list of versions available.
(B) The package version displays the version of the package that’s installed. If the package is not yet installed, the version that appears is the recommended version.
For Asset packages, the version that appears is either the version you already downloaded or the version that is available for download from the Asset Store.
(C) These icons display the status of the package or Asset package:
|A check mark indicates that the package is already installed or enabled.
Note: Installed Asset packages do not display an icon if they are up to date.
|The download icon indicates that the package has an available update. To update your package, follow the instructions for either type of package:
- For Unity packages, see Switching to another package version.
- For Asset packages, see Updating your Asset package.
|The import icon indicates that there is an Asset package available to import.|
|An error icon indicates that something went wrong during installation or loading. For more advice on resolving errors, see Error messages.|
By default, the Package Manager window displays the list of All packages with no Preview packages, but you can filter the list to display only packages installed in your project (including local packages) or display only built-in Unity packages or Asset packages. You can also include Preview packages in the list and search for a specific package by package name, tag name, or package version.
(D) The status bar displays messages about the package load status and network warnings.
(E) Click the reload button to force Package Manager to reload your packages.
Note: If you select the My Assets scope but you don’t see any packages, see Error messages in the Package Manager window for an explanation and solution.
Preview packages do not appear by default in the list of packages on the Package Manager window. This is because preview packages might be unstable, so you should not use them in production.
To include preview packages in the list, select Show preview packages from the Advanced drop-down menu.
