Internet2 is pleased to announce the release of Grouper 2.4, which includes many important enhancements.  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 TIER Program.

Grouper 2.4 is largely a collection of Grouper 2.3 patches, repackaged, updated, and polished.  In addition there are new features too.  Upgrading from 2.3 to 2.4 is a minor upgrade and should be planned for soon.  The Grouper team will now focus on 2.4 patches and 2.5 development.  The timeline for 2.5 will be shorter than the 2.4 timeline, planned for in Spring 2019.  We have a lot of exciting plans for 2.4 patches and 2.5 features; we will be reaching out the community shortly to verify our prioritization.

New Features in Grouper 2.4 since the 2.3 initial release include:

Migrate to new UI

Migrate all screens in Admin and Lite UI to the "New UI" and remove the admin and lite UI. Note, you can add the legacy UI if needed

DeprovisioningDeprovision access from someone to loses an affiliation or changes jobs
AttestationGroups and folders can be marked to require periodic membership review. Reminders will be emailed to group owners
