Computer Vision API 2.0

Thanks for your question @Anonymous .

Per my research the endpoint /vision/v2.0/areaOfInterest doesn't have any official information on deprecation. Meaning the service will continue to be functional.

Having said that, you will have to note that the v 2.0 RecognizeText operations are in the process of being deprecated in favor of the new Read API and needs transition towards the Read API.

If you want to draw a quick comparison between 2.0 and 3.2 endpoints with regards to areaofinterest alone. You could compare the below 2 pages :

v2.0/areaofInterest
https://westus.dev.cognitive.microsoft.com/docs/services/5adf991815e1060e6355ad44/operations/b156d0f5e11e492d9f64307c

v3,2/areaofInterest
https://westus.dev.cognitive.microsoft.com/docs/services/computer-vision-v3-2/operations/b156d0f5e11e492d9f64418d

As per my understanding there is only an addition of an model-version parameter in the newer endpoint - optional parameter to specify the version of the AI model. The values are "latest", "2021-04-01". There is one AI Model version now, & are expected to grow. Similarly, you can see the model version in the 3.2 API response.

You could refer this in order to understand the overall improvement of the V3.x API across all the operations.
