新版本主要是提升了安全和用户管理模块..
官方提到:
With 4.0, administrators can bestow privileges and/or delegate security administration to communities, individuals, and organizations and locations (see below). Community and organization/location privileges cascade to individual users.
Enterprise taxonomy is introduced in 4.0 through "organizations" and "locations," which allow portal administrators to organize content and functionality by general enterprise-wide and division-specific pages. A location can be a geographical subdivision (Europe, U.S. West) or some other entity (Home Office Equipment, Manufacturing).
Communities continue to allow grouping by special interest or skill (across organization), and now support public and private pages. A community's public pages are viewable by any member of the portal community, while private pages are limited to members of the community.
