 ### Computer Vision v3.2 GA
 
 The Computer Vision API v3.2 is now generally available with the following updates:
+
 * Improved image tagging model: analyzes visual content and generates relevant tags based on objects, actions, and content displayed in the image. This model is available through the [Tag Image API](https://westus.dev.cognitive.microsoft.com/docs/services/computer-vision-v3-2/operations/56f91f2e778daf14a499f200). See the Image Analysis [how-to guide](./vision-api-how-to-topics/howtocallvisionapi.md) and [overview](./overview-image-analysis.md) to learn more.
 * Updated content moderation model: detects presence of adult content and provides flags to filter images containing adult, racy, and gory visual content. This model is available through the [Analyze API](https://westus.dev.cognitive.microsoft.com/docs/services/computer-vision-v3-2/operations/56f91f2e778daf14a499f21b).

-* [Spatial Analysis operations](spatial-analysis-operations.md) can be now configured to detect if a person is wearing a protective face covering such as a mask. 
-    * A mask classifier can be enabled for the `personcount`, `personcrossingline` and `personcrossingpolygon` operations by configuring the `ENABLE_FACE_MASK_CLASSIFIER` parameter.
-    * The attributes `face_mask` and `face_noMask` will be returned as metadata with confidence score for each person detected in the video stream

+  * The attributes `face_mask` and `face_noMask` will be returned as metadata with confidence score for each person detected in the video stream
 * The *personcrossingpolygon* operation has been extended to allow the calculation of the dwell time a person spends in a zone. You can set the `type` parameter in the Zone configuration for the operation to `zonedwelltime` and a new event of type *personZoneDwellTimeEvent* will include the `durationMs` field populated with the number of milliseconds that the person spent in the zone.
 * **Breaking change**: The *personZoneEvent* event has been renamed to *personZoneEnterExitEvent*. This event is raised by the *personcrossingpolygon* operation when a person enters or exits the zone and provides directional info with the numbered side of the zone that was crossed.
 * Video URL can be provided as "Private Parameter/obfuscated" in all operations. Obfuscation is optional now and it will only work if `KEY` and `IV` are provided as environment variables.
 * Calibration is enabled by default for all operations. Set the `do_calibration: false` to disable it.
 * Added support for auto recalibration (by default disabled) via the `enable_recalibration` parameter, please refer to [Spatial Analysis operations](./spatial-analysis-operations.md) for details
 * Camera calibration parameters to the `DETECTOR_NODE_CONFIG`. Refer to [Spatial Analysis operations](./spatial-analysis-operations.md) for details.
