 Due to working remotely over the last few weeks, we couldn't do as much manual verification testing as we normally do.

We haven't made any changes we think could have broken anything on these platforms, and our automated tests all passed. In the unlikely event that we missed something, please let us know on [GitHub](https://github.com/Azure-Samples/cognitive-services-speech-sdk/issues?page=2&q=is%3Aissue+is%3Aopen).<br>
 Stay healthy!
