Sitefinity Release Notes

Sitefinity CMS 14.0.7700 (Official Release)

September 15, 2021

Dear Sitefinity CMS customers and partners! We are excited to announce the release of Sitefinity CMS 14.0. Below, you will find the details about what is included in this release.

What's new in Sitefinity 14.0

New Sitefinity DX packaging

With the release of 14.0, we are introducing a new composable packaging of the Sitefinity platform, to provide our customers with more flexibility in selecting the right components for their intended deployments and allow them to expand Sitefinity capabilities in step with evolving needs. Sitefinity 14.0 is delivered as the base Sitefinity DX platform, with a larger number of add-ons available, and the Enterprise package bundle. Sitefinity Insight analytics is now included in the base Sitefinity DX platform package to provide a deeper view of the usage and dynamics of your Sitefinity-powered websites. The Personalize and Test and Optimize add-ons are available separately and utilize more of Sitefinity Insight's capabilities for personalization and A/B testing. 

A new approach to system integration via business events and service hooks

To improve Sitefinity's extensibility and allow you to integrate with practically any third-party service, we introduce the Service hooks mechanism. Using service hooks, you can easily develop event-based low-code integrations with external systems. For instance, you can send a notification to a different application (CRM or marketing automation) when a form has been submitted on a site. In addition, in the Service hooks UI, you can now create custom triggers or choose between over 20 trigger events out of the box that can send data to your integrated services. Although the Service hook module replaces the Webhooks module, Webhooks remain available to everyone in advanced settings and are automatically migrated to Service hooks when you update to 14.0.


Additionally, with the service hooks UI, you can see the status of executed actions, successful or failed, and statistics for service hooks runs with an option to rerun the selected entry.

New authentication protocol

New lightweight, simpler to configure, manage, and more extensible authentication protocol. The new "Default" authentication protocol will significantly reduce complexity (both for development and customer use), improve performance, maintainability and speed up login time. The new authentication protocol is intended to obsolete SimpleWebToken - SWT and OpenId, which rely on an internal identity provider shipped with Sitefinity.
We highly recommend people that upgrade from lower Sitefinity version to switch to the new authentication protocol "Default".

User groups management for multisite

SEO optimization

WebP image support

Sitefinity now supports the WebP image format for images and thumbnails. WebP is an image format employing both lossy and lossless compression and supports animation and alpha transparency. WebP  is designed to create  smaller files  for the same quality, or of higher quality for the same size, than JPEG, PNG, and GIF image formats.  With WebP images, you r pages load faster and your bandwidth costs may be lower.

Developers can use the new extensibility point for the ImageProcessor, provided through the IImageProcessorExtender interface. By implementing this interface, you can write custom logic for image processing in any format.

You can use the new dropdown Convert image format to... in the thumbnails settings dialog to generate thumbnails in the selected format. For example:

  1. You create a profile with "Convert image format to..." set to WEBP, apply this profile to a library, and upload a JPG image in this library. The thumbnail generated for this profile will be in WEBP format.
  2. You set the "Convert image format to..." dropdown to its default value "Keep original format." The thumbnail will have the same format as the parent image.

Here is the new option:
