Evergreen 3.0 features a new, modern staff client that runs in the web browser and can be used on desktop and mobile devices. All functional areas of the system, including circulation, cataloging, acquisitions, serials, reports, booking, administration, and offline circulation, are available in the new staff client. Chrome and Firefox are officially supported for use with the web client.

Library staff will no longer need to download separate software to perform most actions in Evergreen. A Chrome plugin called Hatch will be available as a separate installation for workstations that require seamless, dialog-free printing to multiple printers.

In addition to adding more portability and stability, the new staff client also presents a cleaner and more modern interface for users. By virtue of running in a browser, actions that users are accustomed to performing on other web sites should now be available in the Evergreen client.

The old, XUL client will continue to be available to allow for a gradual transition to the browser-based client, but no new features will be added. The old client will totally be removed from Evergreen in the Fall 2018 3.2.0 release.
