Open source CMS Alfresco has made its Enterprise 3.0 release available today. This is a significant release. It includes the new web application development framework, Surf, a new client for team collaboration called Share, support for multi-tenancy (separating the repository into multiple logical repositories for multiple “tenants”), and a draft CMIS implementation. I haven’t confirmed this personally yet, but at the recent community conference in Washington, D.C., CTO John Newton said that the release includes major performance improvements.
