Common

Features

  • Upgraded Sass to the latest version 1.100.0.
  • Enhanced Syncfusion theme packages to support both consolidated and control-level styles. Each control now provides dedicated style files with an index.css/index.scss that includes required dependencies, enabling simpler and more modular style management.
  • Added support to cancel the drag action using the Escape key in the draggable component.
  • Enabled tree-shaking support in CRG, allowing unused code to be eliminated during bundling for better performance and reduced application size.

  • Introducing Standalone UI SDKs

    We are introducing Standalone UI SDKs to provide greater flexibility in how you license and build your applications.

    In addition to the UI Component Suite, you can now purchase individual SDKs for:

    • Grid SDK
    • Chart SDK
    • File Manager SDK
    • Gantt SDK
    • Scheduler SDK
    • Diagram SDK
    • Rich Text Editor SDK

    Whether you need a single specialized component or a comprehensive UI suite, you can now choose the product that best fits your application requirements and budget.

    Starting with this release, Gantt, Scheduler, Diagram and Rich Text Editor components are now available as standalone SDKs and licensed separately. While the UI component suite continues to provide the comprehensive collection of the remaining high-performance UI components.

    Note: This change applies to the new product purchases only. Existing customers will continue to receive access to all the UI components, including Gantt, Scheduler, Diagram and Rich Text Editor, according to their current licensing. No changes are required for the existing customers.

    Breaking Changes

  • SCSS files are no longer supported within control packages and EJ2 package, and direct SCSS imports will not work. Use SCSS theming by importing styles from centralized theme packages.
