-> To maintain a smooth operation of your models, install the open-source [Florence 2 model](https://huggingface.co/microsoft/Florence-2-large) and use its Region to segmentation feature, which allows for a similar background removal operation.
+> The segmentation feature of the open-source [Florence 2 model](https://huggingface.co/microsoft/Florence-2-large) might meet your needs. It returns an alpha map marking the difference between foreground and background, but it doesn't edit the original image to remove the background. Install the Florence 2 model and try out its Region to segmentation feature.

 ## January 2025
 
+### Face liveness detection GA
+
+The Face liveness detection feature is now generally available (GA).
+
+* Server-side API: [Face API v1.2](/rest/api/face/operation-groups?view=rest-face-v1.2)
+* Client-side SDK: [Azure AI Vision SDK 1.0.0](https://github.com/Azure-Samples/azure-ai-vision-sdk/releases/tag/1.0.0)
+
+This SDK allows developers to utilize face liveness checks on both native-mobile applications and web-browsers applications for identity-verification scenarios.
+
+The new SDK supports both Passive and Passive-Active modes. The hybrid Passive-Active mode is designed to require Active motion only in poor lighting conditions, while using the speed and efficiency of Passive liveness checks in optimal lighting. 
+
+For more information, see the [SDK release notes](https://github.com/Azure-Samples/azure-ai-vision-sdk/releases/tag/1.0.0).
