Changelog

Detailed change logs are linked to in the Quick Links below. Here are some critical call outs.

Cosmos

• azure.cosmos.errors module deprecated and replaced by azure.cosmos.exceptions
• The access condition parameters (access_condition, if_match, if_none_match) have been deprecated in favor of separate match_condition and etag parameters.
• Added query Distinct, Offset and Limit support.

Event Hubs

• Added support for tracing (issue #7153).
• Added new boolean type parameter track_last_enqueued_event_properties in method EventHubClient.create_consumer().
• Added new property last_enqueued_event_properties of EventHubConsumer which contains sequence_number, offset, enqueued_time and retrieval_time information.
• Removed support for IoT Hub direct connection. EventHubs compatible connection string of an IoT Hub can be used to create EventHubClient and read properties or events from an IoT Hub.
• Removed support for sending EventData to IoT Hub.
• Removed parameter exception in method close() of EventHubConsumer and EventHubProcuer.

Key Vault

• Restructured the Certificate, Key, and Secret models and renamed them to KeyVaultCertificate, KeyVaultKey, and KeyVaultSecret.
• Renamed methods to more clearly reflect their intended uses.
• Both async and sync versions of deleting and recovering keys and secrets now return pollers that can be awaited if necessary
• For more specific details about these changes, see the respective certificate, key, and secret changelogs.

Storage

• The first preview for azure-storage-file-datalake has been released to allow accessing Azure Storage data with DataLake semantics when hierarchical namespace is enabled
• azure.storage.file is now azure.storage.fileshare.
  • The package is renamed from azure-storage-file to azure-storage-file-share along with renamed client modules.
• New API for stream download responses for blobs and files. This object is no longer iterable.
• Client and model modules are now internal.
• Changed optional params to keyword only in queues and files.
• enqueue_message is now called send_message in queues.
• Other breaking changes like renaming LeaseClient in blobs to BlobLeaseClient.

App Configuration

• Etag and match_condition of delete_configuration_setting are now keyword argument only

Identity

• DefaultAzureCredential accepts an authority keyword argument, enabling its use in national clouds
• All credentials with tenant_id and client_id positional parameters now accept them in that order
• Optional parameters for several credentials are now keyword arguments
• Authenticating with a single sign-on shared with other Microsoft applications only requires a username when multiple users have signed in
• Async credentials default to aiohttp for transport
• Known issue (#8292): DefaultAzureCredential and SharedTokenCredential raise exceptions on Python 3.8 on Windows
