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. You can also include Preview packages in the list and search for a specific package by package name, tag name, or package version.

(E) The reload reload button, which you can click to force Package Manager to reload your packages.


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.

要在列表中包含预览包,请从 Advanced 下拉菜单中选择 Show preview packages
