   The new SDK supports all the features of the v2.0 REST API for Form Recognizer. For example, you can train a model with or without labels and extract text, key value pairs and tables from your forms, extract data from receipts with the pre-built receipts service and extract text and tables with the layout service from your documents. You can share your feedback on the SDKs through the [SDK Feedback form](https://aka.ms/FR_SDK_v1_feedback).
