Release highlights

Core 0.28.0 Changelog

Breaking Changes

  • Added a lifetime parameter to TokenRequestOptions.
  • Added the ability to configure pipeline configuration independently from ClientOptions. This adds a new optional PipelineOptions parameter to azure_core::http::Pipeline::new(). If not specified, it defaults to the expected options for azure_core services.
  • Changed FromStr for RequestContent<T, F> to RequestContent::from_str().
  • Changed TryFrom<&'static str> for RequestContent<T, F> to RequestContent::from_static().
  • Changed TryFrom<Bytes> for RequestContent<T, F> to From<Bytes> for RequestContent<T, F> because it was already infallible.
  • Removed TryFrom<Vec<u8>> for RequestContent<T, F> since RequestContent::from() already exists.
  • Removed feature reqwest_rustls_tls. See README.md for alternative HTTP client configuration.
  • Removed the fs module including the FileStream and FileStreamBuilder types. Moved to examples/ for typespec_client_core to copy if needed.
  • Removed the setters macro.
  • Renamed RawResponse to BufResponse. New RawResponse contains complete body as Bytes used in ErrorKind::HttpResponse.

Features Added

  • Added RawResponse to ErrorKind::HttpResponse that contains the HTTP status code, headers, and complete error response body.
  • Added RequestContent::from_slice().
  • Added TokenRequestOptions { method_options: ClientMethodOptions }.
  • Added TryFrom<T> for RequestContent<T, JsonFormat> for JSON primitives.
  • Added support for WASM to the async_runtime module.
  • Added logging policy to log HTTP requests and responses in the pipeline. As a part of this change, sanitization support was added to places which log HTTP headers and URLs. The azure_core::http::ClientOptions has been enhanced with a LoggingOptions which allows a user/service client to specify headers or URL query parameters which should be allowed. Note that the sanitization feature is disabled if you build with the debug feature enabled.
  • Added support for a new azure_core::error::http::ErrorResponse structure which describes an error according to the Azure REST API guidelines.
  • Added a new azure_core::http::check_success(BufResponse) function to convert a buffered response to an ErrorKind::HttpResponse.

Core - AMQP 0.7.0 Changelog

Breaking Changes

  • Distinguish remote disconnect and remote closed errors by origin

Core - Macros 0.2.0 Changelog

Other Changes

  • Updated dependencies.

Core - OpenTelemetry 0.2.0 Changelog

Other Changes

  • Updated dependencies.

Cosmos DB 0.27.0 Changelog

Other Changes

  • Updated Core SDK dependencies

Event Hubs 0.7.0 Changelog

Breaking Changes

  • ProducerClient::send_batch now consumes its batch argument.
  • RetryOptions::max_retries is a u32 not a usize.

Features Added

  • Reconnect support for EventHubs operations.
  • Enable Geo Replication support in Event Hubs consumers and producers.

EventHubs Checkpoint Store for Azure Blob Storage 0.1.0 Changelog

Features Added

  • Initial Release

Identity 0.28.0 Changelog

Features Added

  • Credentials retry HTTP requests by default.

Breaking Changes

  • Removed all ClientCertificateCredentialOptions methods
  • Removed TokenCredentialOptions. HTTP client options are now set on ClientOptions. Credentials which formerly got an authority host from this type now get it from an authority_host field in their own options type.
  • Replaced DefaultAzureCredential with DeveloperToolsCredential. This new type is excluded from WASM32 builds because it can’t authenticate in a WASM runtime environment; however, neither could DefaultAzureCredential, which wasn’t properly excluded.

  • Changed FromStr for RequestContent<T, F> to RequestContent::from_str().
  • Changed TryFrom<&'static str> for RequestContent<T, F> to RequestContent::from_static().
  • Changed TryFrom<Bytes> for RequestContent<T, F> to From<Bytes> for RequestContent<T, F> because it was already infallible.
