Nintex Automation K2 (5.9.1) is now available to download on Nintex Customer Central (filter on “K2” in the platform dropdown under Product Releases) or on Nintex Partner Central (under the Products > Product Downloads menu). This release introduces several amazing new features, including:

  • Built-in, locally hosted AI: Organizations can embed AI directly into forms and workflows using out-of-the-box actions such as sentiment analysis and severity scoring. AI-driven decisions, including routing, prioritization, and issue detection, run entirely within the customer environment, with no external dependencies required to operate the platform. 
  • Simplified identity federation: Easier onboarding for OIDC-compatible identity providers, combined with a guided setup experience and built-in synchronization, reduces the complexity of managing users across systems and keeps identity data current without manual intervention. 
  • Enhanced accessibility and usability: WCAG runtime improvements for forms, including updates to contrast, zoom behavior, and focus states, help organizations meet accessibility standards. A new high-contrast style profile and greater control in the Workflow Designer, including optional auto-save behavior, improve usability for both end users and developers. 

K2 release 5.9.1 is a Short-Term Support (STS) release, providing one year of standard support (reaching end of support on 31 March 2027). All stability and security fixes released since 5.9 are included in this release.
