Sitefinity Release Notes

Sitefinity CMS 13.3.7600 (Official Release)

March 10, 2021

Dear Sitefinity CMS customers and partners! We are excited to announce the release of Sitefinity CMS 13.3. Below you will find the details about what is included in this release.

What's new in Sitefinity 13.3

Reinvented Shared Content UI

This release delivers new UI for the Shared Content module with feature parity. You now get the familiar benefits of the New UI when using the Shared Content module:

  • Easier navigation and filtering with the improved sidebar
  • The new rich text content editor
  • Bulk assign tags and categories
  • View all the pages that use a specific content block

A new UI module to manage scheduled / background tasks

A new page in the administrative backend was added. It allows administrators to manage all scheduled tasks. They can filter and search for specific tasks, check the task status, retry failed tasks, resume and stop tasks. Other improvements include:

  • Error messages are displayed directly in the UI
  • Failed tasks are automatically restarted
  • Trace information is displayed for scheduled tasks
  • Progress bar is visualized for the search index task that displays the currently indexed content
  • There is an option to forbid scheduled tasks execution on servers

Advanced site access management with site-specific users and site-specific settings

  • Site-specific users
    The new user groups feature enables you to create separate user groups for separate sites from the multisite instance. Such isolation in the administrative backend prevents one backend user group to access or alter the information belonging to another group. You can still have global administrators and users that can manage all sites, but also local administrators and users that can manage only specific sites.
    Learn more...
  • Provider reuse
    Sitefinity CMS now implements virtual providers that enable you to efficiently share and manage data sources for each content type. These virtual providers are loaded only when used for the first time and not during system startup, which improves system load times and dramatically reduces configuration entries of providers.
    This feature introduces new APIs, but the creation and use of providers should remain unchanged for users.
    Learn more...

  • Site-specific settings
    Each Sitefinity CMS instance has a default configurations set. Each site that belongs to this instance can now have its own, site-specific settings. These settings can be managed by global or local administrators.

New translation connector for Lionbridge translation service

Due to API changes, the current Lionbridge Freeway and Clay Tablet translation connectors will be deprecated by the end of 2021. To continue using the services, you must configure the new Lionbridge translation connector.

Deprecated capabilities

  • Amazon Cloud Search is no longer supported. If you have Amazon CloudSearch setup, the system status dashboard widget will report an error. We suggest configuring one of the three built-in search services instead.


What's improved

Change owner command available in AdminApp

  • You can now use the change owner command for specific content types in addition to pages.
