Zimbra Announces Move to OSI-based Licensing for Zimbra Collaboration 8.5 Open Source Edition

Public beta of version 8.5 available today includes licensing improvements that demonstrate commitment to community-powered open source innovation

DALLAS – June 4, 2014 – Zimbra, a global leader in unified collaboration software, announced today that it is making key changes to its open source software licensing. In order to build an even stronger foundation for community-powered innovation, the company is moving to Open Source Initiative (OSI)-approved licenses with its summer release of Zimbra Collaboration 8.5. The Zimbra Collaboration server platform will be licensed under the GNU Public License version 2 and the Zimbra Collaboration web application will be licensed under the Common Public Attribution License (CPAL) version 1.

Today, more than 60,000 community members contribute to the Zimbra Collaboration open source project. With more than one million downloads, the open source edition of Zimbra Collaboration is being used by approximately 600 million people in 135 countries.

By moving to OSI-approved licenses, Zimbra will increase contributions from the open source community that will drive innovation and enhance the quality of its software. Zimbra also looks forward to increased compatibility with other open source projects, so that customers, partners and end users receive greater benefit from integration across the open source software ecosystem.

“If there was ever any doubt about Zimbra’s commitment, today’s licensing announcement is more proof that our product strategy is securely tied to the open source community,” said Rob Howard, chief technology officer at Zimbra. “Leveraging our open source community will help us bring continuous innovation to the inbox,” continued Howard.  

Members of the open source community will begin to see these licensing changes go into effect in the open source repository with the public beta of Zimbra Collaboration 8.5. The public beta starts today and is open to all participants.
