Grouper is an enterprise access management system designed for the highly distributed management and diverse information technology environment common to universities. Grouper is one of the key components in the InCommon Trusted Access Platform.

New Features in Grouper v4

 Grouper v4 includes many helpful new features, as listed below, as well as the enhancements provided in Grouper 2.5 updates. 

** As of March 2023, Grouper v4 is the stable no-enhancement version of v2.6. See versioning page **

The upgrade from 2.5 (more recent) to v4 is not a substantial change.  The database did not change much. 

You are required to use a container when running Grouper. This will ensure you have consistent directory structure, the correct version of libraries, and low risk and low effort upgrades.  There are instructions to make using the container as easy as possible.
