• Style Profile Designer:
  • The Check Box, Rating, and Radio Button controls are now style profile aware. You can set the background color, the outline, and the main color for each control type using the advanced colors. If you are using custom code (CSS) that targets these controls, your custom code may no longer work.
  • The ToolBar Button control's icon is also now style profile aware. You can set the icon's highlight, destructive, base, and base secondary color using the advanced colors. If you are using custom code (CSS) that targets the icon of this control, your custom code may no longer work.
• New property added to Open subview/subform rule action, called Vertical Align.

• New property added to Exchange Online Email SmartObject List method, called "From Address".

• Microsoft has ended support for Silverlight on October 12, 2021. As a result the Nintex K2 legacy Silverlight designer will be removed from Nintex K2 Cloud with the next release. Ensure you rebuild these in the Workflow Designer (HTML).

• The Style Profile Designer is not available in Internet Explorer (IE), as it uses CSS custom properties (CSS variables) which is not compatible with Internet Explorer. We suggest you use a modern browser for the K2 Designer, such as Google Chrome.
• The jQuery version used in SmartForms has been upgraded to jQuery 3.6.3 and all jQuery libraries updated to reduce vulnerabilities and ensure your solutions are secure. See jQuery upgrade for SmartForms for more information and how it affects existing solutions.
• Download the enhanced Package and Deployment tool from https://<runtimeurl>/Management/Remote.

Please see the Package and Deployment Considerations topic for further considerations about working with the Package and Deployment tool.
• If you are using K2 for SharePoint, you must update the app and run through the K2 for SharePoint registration wizard after upgrade. See the following steps:
  1. Click the K2 for SharePoint app from the Site Contents page or Quick Launch menu of the app catalog site and run through the Registration Wizard by clicking the Registration Wizard link in the Administration section to register the app with your K2 environment's URL. (If you do not see the Registration wizard, make sure you are on the app catalog).
  2. (This step is only required if there were changes to the K2 for SharePoint app. See the K2 for SharePoint release notes for information about previous releases and the latest version.)
     Deploy the app to one or more site collections using the Manage App Deployments page in SharePoint. A link to this page is provided on the K2 for SharePoint settings page. It is recommended you do this by paths rather than individual URLs, but individual URLs give you more control regarding which site collections have K2 integration. You should deploy as a SharePoint Administrator if you are deploying to multiple site collections.
