Nintex Automation K2 (5.9) is now available to download on Nintex Customer Central (filter for "Nintex Automation" in the products drop-down menu) or on Nintex Partner Central (under the Products > Product Downloads menu). This release introduces customization capabilities, accessibility improvements, and platform optimizations, including:

  • Custom Control Framework. Build and manage custom form controls directly within K2. Create purpose-built interface components that match your specific UI requirements, manage them centrally, and deploy consistently across your applications.
  • Accessibility improvements. Runtime SmartForms now include enhanced support for assistive technologies, helping ensure your workflow applications are accessible to all users.
  • Enhanced error codes in the REST broker. Integration troubleshooting gets easier with descriptive error responses that help you identify and resolve issues faster across your RESTful connected systems.
  • Direct file handling. JSSP endpoints now support direct file operations, eliminating the need for base64 encoding and simplifying file management in your JavaScript based integrations.
  • OData v4 enhancements. Improved support for complex data relationships and better integration capabilities to support Microsoft Dynamics 365 and Business Central environments.
  • Performance optimizations. Authorization framework improvements deliver significant performance gains in large-scale Active Directory environments.
  • Add external links to applications. New organizational tools, including the ability to add hyperlinks to K2 categories, keep design teams productive.
  • Improved license reporting. Export usage reports directly to CSV format for easier analysis and license management.
  • SharePoint migration support. New user interface for the Nintex for SharePoint workflow  importer simplifies bulk migrations from legacy Nintex for SharePoint solutions.

K2 release 5.9 is a Long-Term Support (LTS) release, providing 2 years of standard support and 2 years of extended support (4 years total). All stability and security fixes released since 5.8 are included in this release.
For complete details on these features, check out the release notes available on help.nintex.com.  Join us for the customer enablement webinar on December 3rd to see live demonstrations and implementation guidance from the product team.

Hi Codi,

I am really excited to try out this custom controls feature. I tried to download but the download doesn’t seem to be working.

Could you please drop a link here to some user guide on creating custom controls as well as from where we can download it.

Regards,

Yasir Akram
