+
+The constructor `Cursor(Device, ImageData, ImageData, int, int)` has been **deprecated** in SWT due to its limited DPI support.
+
+You should now use the new constructor:
+
+```
+Cursor(Device, ImageDataProvider, int, int)
+```
+
+The new constructor with `ImageDataProvider` gives you the best image for the cursor for all zoom levels, ensuring proper support for high-DPI displays and modern environments.
+
+Please update your code to use the new constructor signature. For more details, see the [pull request](https://github.com/eclipse-platform/eclipse.platform.swt/pull/2563).
