Three important technology changes in 2026
Exchange Online EWS
Microsoft will retire Exchange Online EWS access on 1 October 2026. K2 environments that still rely on EWS may experience disruption to workflow emails and task notifications.
Action: Confirm your K2 version and plan the move to Microsoft Graph.
NET 8 support
.NET 8 reaches end of support on 10 November 2026. K2 uses .NET in several important platform services, including configuration, authentication and JavaScript-based service integration.
Action: Identify and test the appropriate Nintex fix pack for .NET 10 support.
Chromium XSLT
Chromium browsers will remove client-side XSLT support from 17 November 2026. K2 uses this functionality in certain design-time and runtime experiences.
Action: Confirm your browser exposure and apply the appropriate Nintex fix pack to a supported K2 version.
Also check your K2 product support status
Nintex K2 Five 5.6 reaches the end of extended support on 31 August 2026, while Nintex Automation 5.8 reaches the end of standard support on 30 September 2026.
Your appropriate upgrade path will depend on your current version, fix-pack level, integrations and support agreement.
