Zimbra Collaboration Open Source Edition
Special Note: Zimbra made key changes to its open source software licensing to build an even stronger foundation for community-powered innovation. With the release of Zimbra Collaboration 8.5, Zimbra officially moved to Open Source Initiative-approved licenses. The Zimbra Open Source Edition Web Client Code is released under the Common Public Attribution License, version 1.0 (CPAL v.1). The Zimbra Open Source Edition Server Code is released under GNU General Public License, version 2 (GPL v.2). The Zimbra Open License Community Zimlets Code is released under the Common Public Attribution License, version 1.0 (CPAL v.1). Versions prior to version 8.5 will remain under the Zimbra Public License 1.4. By moving to OSI-approved licenses, Zimbra hopes to increase contributions from the open source community and increase compatibility with other open source projects, so that customers, partners, and end users receive greater benefit from integration across the open source software ecosystem.
