Nintex K2 Cloud release notes

New Features

Localization

Nintex K2 Cloud is now also available in Arabic, French, German, and Spanish languages delivering a fully localized automation experience. You can set the design time and runtime translation language allowing you to use the product in your preferred supported language. See Localization for information about localization in your environment and fall-back behavior.
The following additional features are available in Localization:
- Enable or disable translations for views and forms in the Designer by selecting or deselecting the Translations property of the view or form.
- Enable or disable translations per product for Workspace and Management, Runtime Forms, and the Designer in Management>Translation Settings.
- The Find uses button in Forms Translation>Translations allows you to view a list of instances for which a translation has been used within a view or form.
- The Filter For Language option in SmartObject text and memo type properties allows you to translate data within a SmartObject at runtime.
- Use the _ui-culture query string parameter to test a specific language translation on a view or form at runtime.
- Create translation keys for properties that are mapped from the Context Browser in the Designer.

SmartForms
- Dynamic Chart control added that allows you to use a SmartObject as its data source to display customized data across various chart types, including area, bar, column, line, and pie charts.
- Progress control added that allows you to display custom progress steps based on a pre-configured data source.
Workflow designer
- Workflow design time versioning is introduced with this version of the product. You now have the option to save a draft (minor) version of the workflow. You can manage minor and major versions from the Designer and Workflow Designer, allowing you to have a clean design time experience, while all major versions are managed in Management.
SharePoint
- SharePoint:
  - Microsoft has announced the deprecation of the SharePoint App Add-In Model, which is used to integrate the product with SharePoint Online.
    Note: The App Add-In model support only affects SharePoint Online
    To continue using the product with SharePoint Online, you can now migrate your Nintex K2 for SharePoint solutions to Nintex K2 Cloud (SPFx) app for SharePoint Online which supports SharePoint Framework (SPFx).

Integration

Nintex RPA Broker service added to the list of service types. Use this service to integrate the product with Nintex RPA.
The OData endpoint broker now supports OData version 4.
The REST endpoint broker now supports OpenAPI Specification (OAS) v3.

Enhancements

SmartForms
- Toolbar Button control - New toolbar icons added to the list of options for the Toolbar Button control such as Attachment, Comment, Export and more. You can also use the Set a control's properties rule action to set these icons at runtime. New icon sets have also been implemented for the SharePoint 2013 theme and Platinum theme.
- Dynamic theme - The Dynamic theme has been updated to introduce several key enhancements:
  - Material focused styling: The theme now embraces a material design approach, improving the overall aesthetic and user experience across all devices, including mobile.
  - Font update: Fonts have been updated to the modern Poppins Google font, with revised sizing for better readability.
  - Chart series colors: The color palette for chart series has been updated with more vibrant, saturated colors, eliminating the previous desaturation to brown tones.
  - Toolbar icons: All toolbar icons have been converted to SVG format for sharper resolution and better scalability.
  If you want to use the previous version of the Dynamic theme instead of the new modernized theme, you can download the CSS from Nintex Community and use it as a custom theme.
- Control styles - Base icon colors have been added to the style profile designer to customize icon appearance. You can also use control-specific colors to further customize the appearance of the control.
- Icon style aware - The icons of some controls such as picker, worklist, multi-select, calendar, rich text, drop-down, lookup, view expansion, dialog, tree, tree widget, paging, and toolbar have been updated to SVG format, ensuring sharper resolution and better scalability. The Dynamic theme has been applied to these icons and you can customize certain elements of the icons further by using the style profile.
- Optimized SQL functions to improve performance for Identity Container lookups.
- Upgraded Micros to .NET 8
Workflow Designer
- The time interval boxes in steps such as the Task, Timer, and Call Sub Workflow have been enhanced to allow you to expand and collapse the boxes for ease of use.
Integration
- Oracle 21c and 23ai support, see known issue.

Behavioral changes

SmartForms
- Legacy theme - When creating a new form, the "Use Legacy Theme" check box is now unchecked by default. New forms are automatically assigned the modern Dynamic theme, although you can still choose to apply any of the legacy themes if preferred. The default style profile for the Dynamic theme includes standardized color settings such as main accent, page background, and content background to ensure a consistent appearance across new forms. Existing forms are not affected by this change. If you want to see the legacy style profile behavior with enhanced modern themes, check out the Nintex Gallery for examples.
- Style profile - When the "Use Legacy Theme" check box is selected on a form and a style profile is added, the check box is now automatically unchecked. This eliminates the need for manual intervention. The same behavior applies when switching style profiles: if a style profile is linked to a form and the "Use Legacy Theme" option is checked, selecting a different style profile will automatically uncheck the "Use Legacy Theme" check box.

Deprecated functionality and components

Internet Explorer 11 is unsupported and the Designer and runtime functionality is blocked.

Considerations

Microsoft Azure Active Directory is now Microsoft Entra ID
Applications using Azure Active Directory Authentication Library (ADAL) for authentication and authorization capabilities have been migrated to the Microsoft Authentication Library (MSAL). See Migrate applications to the Microsoft Authentication Library (MSAL) for more information.
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. Once downloaded, log a ticket with Nintex Customer Central to provide your public IP address ranges to K2 Operations. This allows access to your K2 Cloud environment from your network. Please see the Package and Deployment Considerations topic for further considerations about working with the Package and Deployment tool.
If you are using K2 Cloud for SharePoint, you must update the app and run through the K2 Cloud for SharePoint registration wizard after upgrade. See the following steps:
1. Click the K2 Cloud 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 Cloud 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 Cloud 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.
SharePoint integration - See Nintex K2 Cloud (SPFx) app overview for considerations when using the legacy Nintex K2 Cloud for SharePoint app and the new Nintex K2 Cloud (SPFx) app.
If you replace an existing Task step with a new Task step in a workflow, and the Form rules of the existing SmartForm Task remain but it shows the new Task’s name, follow the following article to successfully fix the issue: Known Issue : Old Workflow Task name in SmartForm overwritten by new Task
Google is rolling out changes to block third-party cookies in the Google Chrome browser. This affects SharePoint integration which loads Nintex K2 forms in an iframe. As a result, you may experience issues when navigating to a SharePoint integrated form. See Troubleshooting for more information and resolution to the third-party cookie phaseout.

Known Issues

Issue: When you configure a specific custom workflow step created for a single SQL Service Instance and Service Object in a workflow, the configuration panel allows you to select a service instance that is not linked to the specific custom workflow step.
