The new content viewing API in release 8.0 allows content to provide a default rendering for other aggregated lists (such as tagged content, liked content, mention lists, bookmark lists,etc.) similar to the way searchable content can identify how it should be rendered in search results.
In release 8.0, email notifications and their associated templates are now implemented as plugins. This change adds extensibility for development.
URLs are no longer configured as using the siteurls.config file. The URL configuration is now handled by the Fully qualified URL plugin - by enabling and choosing an execution condition or disabling it. This change adds extensibility for development.
The Job Service (formerly called Job Scheduler) now consists of a number of job plugins. As plugins, they add extensibility for development.
Developers can create their own permissions and verify that users have them from their third-party code just as they are created or used in Zimbra Community. Previously, setting permissions was completely manual for third-party applications.
Cookie SSO is now implemented as a plugin. This change adds extensibility for development.
For more information about the API changes and a listing of them, please see the Developer Documentation.
