Sitefinity Release Notes

Sitefinity CMS 12.2.7200 (Official Release)

November 06, 2019

Dear Sitefinity CMS customers and partners! We are excited to announce the release of Sitefinity CMS 12.2. This version contains: major performance update; form rules for email notifications; out of the box designers for custom widgets; custom error pages without writing any additional code; webhook mechanism that allows you to subscribe external services to different Sitefinity CMS events; individual preferences for users of the new backend UI; New UI support for Backend screens tweaks of dynamic modules; copy/paste MVC widget settings.

What's improved

Performance updates

One of the focuses of this release was speeding up key user scenarios.

  • Reduce startup time of Sitefinity CMS instances by more than 80% in some scenarios
  • Numerous optimizations throughout the Sitefinity CMS code that make the end-users and content creators' experience snappier. Simply by upgrading to Sitefinity CMS 12.2, you will experience reduced page loading times, database pressure, and, due to algorithmic changes in core Sitefinity CMS operations, almost every other activity.
    • Startup time - The impact of these improvements will be visible during development, as well as in cases of application restarts in production environments
    • Server Response Time (TTFB) - The impact of these improvements will be mostly visible after content changes that invalidate the output cache, as well as when the output cache expires on its own
    • Loading of pages in the new content editing experience is much faster

To fine-tune the performance, you can use some newly introduced settings:

  • Improved Sitefinity CMS startup by changing the way Sitefinity CMS loads assemblies with Feather controllers at startup. This is controlled by a new option, turned on by default, located in Settings -> Advanced -> Feather -> Use cached controller container assemblies
  • Control the automatic loading of the Ninject extensions. When Sitefinity CMS starts it looks for and loads custom Ninject modules only when this setting is enabled. You can find this setting in Settings -> Advanced -> Feather -> Automatically load Ninject extensions

What's new

Form rules for email notifications

The enhanced form rules enable you to configure the forms to send notification emails to the appropriate group of people in your organization, based on the submitted form response.

Out of the box designers for custom widgets

Sitefinity CMS now comes with user-friendly, enhanced, autogenerated widget property editors. You can now set properties with type-specific field editors. You can also group property fields in sections and views and validate user input. In addition, you can conditionally display specific fields, depending on your custom requirements.

Custom error pages

You can now create custom error pages for different error codes as regular Sitefinity CMS pages, without writing any additional code. This makes it easier and faster to create them for all your projects. Custom error pages will improve your website security and user browsing experience.

Webhook mechanism

The Webhook allows you to subscribe external services to different Sitefinity CMS events, without writing any custom code. When an event registered in the Sitefinity CMS EventHub system is triggered, the Webhook sends the event data in JSON format via a POST request to the Webhook URL. Webhook also enables developers to extend Sitefinity CMS with new capabilities that follow the micro-service architecture.

Backend user preferences

Users of the new backend UI can now set their own individual preferences in their Sitefinity CMS account. The preference settings control the presentation of onboarding tips, the behavior of the CMS after publishing a page, and several accessibility settings.

The new editing experience support for Backend screens tweaks of dynamic modules

The new editing experience now supports columns ordering based on backend customizations for dynamic types, related media, related data, and fields definitions settings.

Reuse MVC widget settings

To facilitate reuse of widgets, you can copy the properties from the advanced settings of one widget and paste them directly in the advanced settings of another widget of the same type. This operation works for a Content block or custom MVC widgets in the New UI.

The new LiveChat Sitefinity integration allows you to easily add LiveChat to your Sitefinity website. Engage with your customers in real-time while they are visiting your website to answer their questions and solve their problems.
