See the main docs for changes in versioning and flags, this section focuses on how the generated code differs.

• The credential system has been completely revamped:
  • Previously we had used azure.common.credentials or msrestazure.azure_active_directory instances, which are no longer supported. We now use credentials from azure_identity and the AzureKeyCredential from azure-core.
  • The credentials parameter to the service client has been renamed to credential
• The config attribute is no longer exposed on the client, and custom configurations should be passed as a kwarg. For example, we now have Client(credential, subscription_id, enable_logging=True). For a complete set of supported inputs to your client, see our list of acceptable initialization parameters in azure-core.
• You can't import a version module anymore, use __version__ instead. Additionally, we only generate a version file if you specify a package version on the command line (--package-version), or you tell AutoRest during generation time to keep the current version file in the directory (--keep-version-file). See our flag index for more information on these 2 flags.
• Long running operations that used to return a msrest.polling.LROPoller now return a azure.core.polling.LROPoller by default. These operations are also now prefixed with begin_.
• The exception tree has been simplified, and now most exceptions are an azure.core.exceptions.HttpResponseError. CloudError has been removed.
• Most of the operation kwargs have changed. The most noticeable are:
  • raw has been removed. We now use cls, which is a callback that gives access to the internal HTTP response for advanced users.
  • For a complete set of supported options, see the acceptable parameters to operations in azure-core.

• Type annotations using the standard typing library. SDKs are mypy ready!
• This client has stable and official support for async. Look in the aio namespace of your generated package to find the async client.
• The client now natively supports tracing with OpenTelemetry. Use the flag --trace to generate code for this, and you can see our tracing docs for more information.

Note: OpenCensus has been deprecated and is no longer supported. Please use OpenTelemetry instead.
