 **Noteworthy changes and features**

 - Authentication: The packages `@azure/ms-rest-nodeauth` or `@azure/ms-rest-browserauth` are no longer supported. Use package [@azure/identity](https://www.npmjs.com/package/@azure/identity) instead. Select a credential from Azure Identity examples based on the authentication method of your choice.
 - Callbacks: Method overloads that used callbacks have been removed and the use of promises is encouraged instead.
 - List operations now return an iterable result that follows the `PagedAsyncIterableIterator` interface as opposed to the previous model where you had to make a new request using the link to the next page.
