Installed Package Types

There are two types of installed packages: packages with enhanced functionality and packages with legacy functionality. Various details make it easy to tell whether you’re looking at a legacy package or enhanced package. All legacy packages have a banner at the top indicating that it’s a legacy package and a Licenses tab. Enhanced packages have an Access tab.

We recommend that you create packages with enhanced functionality to use the latest updates and enhancements, including OAuth 2.0 functionality.

The ability to create legacy packages was deprecated in August 2019. All new packages are enhanced packages.
