Breaking Changes:

• ⚠️ (server) The generated crates no longer have the aws-lambda feature flag enabled by default. This prevents the aws-lambda feature from being automatically enabled in aws-smithy-http-server when the SDK is not intended for AWS Lambda.

New this release:

• 🎉 (server) All relevant types from aws-smithy-http-server are now re-exported within the generated crates. This removes the need to explicitly depend on aws-smithy-http-server in service handler code and prevents compilation errors caused by version mismatches.

• 🎉 (all, smithy-rs#3573) Support for the rpcv2Cbor protocol has been added, allowing services to serialize RPC payloads as CBOR (Concise Binary Object Representation), improving performance and efficiency in data transmission.

September 26th, 2024

New this release:

• 🐛 (client, smithy-rs#3820) Fixed a bug with the content length of compressed payloads that caused such requests to hang.

Internal and aws-sdk-rust-related changes only with this release

September 9th, 2024

Breaking Changes:

• 🐛⚠️ (server, smithy-rs#3813) Operations with event stream member shapes must include ValidationException in the errors list. This is necessary because the member shape is a required field, and the builder for the operation input or output returns a std::result::Result with the error set to crate::model::ValidationExceptionField.

New this release:

• 🎉 (server, smithy-rs#3803) Setting the addValidationExceptionToConstrainedOperations codegen flag adds aws.smithy.framework#ValidationException to operations with constrained inputs that do not already have this exception added.

  Sample smithy-build-template.json:

  {
      "...",
      "plugins": {
          "rust-server-codegen": {
              "service": "ServiceToGenerateSDKFor",
                  "module": "amzn-sample-server-sdk",
                  "codegen": {
                      "addValidationExceptionToConstrainedOperations": true,
                  }
          }
      }
  }
  

• 🐛 (all, smithy-rs#3805) Fix bug in DateTime::from_secs_f64 where certain floating point values could lead to a panic.

August 28th, 2024

Breaking Changes:

• ⚠️ (all, smithy-rs#3800) Upgrade MSRV to Rust 1.78.0.

New this release:

• 🐛 (client, smithy-rs#3798) Fix the execution order of modify_before_serialization and read_before_serialization in the orchestrator. The modify_before_serialization method now executes before the read_before_serialization method. This adjustment may result in changes in behavior depending on how you customize interceptors.
• (client, smithy-rs#1925) Backport connection poisoning to hyper 1.x support
• 🐛 (client, aws-sdk-rust#821, smithy-rs#3797) Fix the Length::UpTo usage in FsBuilder, ensuring that the specified length does not exceed the remaining file length.
• 🐛 (client, aws-sdk-rust#820) Re-export ByteStream's Length and FsBuilder. By making these types available directly within a client crate, customers can use ByteStream::read_from without needing to import them separately from the aws-smithy-types crate.

Internal changes only with this release

August 8th, 2024

New this release:

• 🐛 (client, smithy-rs#3767) Fix client error correction to properly parse structure members that target a Union containing that structure recursively.
• 🐛 (client, smithy-rs#3765, smithy-rs#3757) Fix incorrect redaction of @sensitive types in maps and lists.
• (client, smithy-rs#3779) Improve error messaging when HTTP headers aren't valid UTF-8

July 16th, 2024

New this release:

• (client, smithy-rs#3742) Support stringArray type in endpoints params
• (client, smithy-rs#3755) Add support for operationContextParams Endpoints trait
• (client, smithy-rs#3591) aws_smithy_runtime_api::client::orchestrator::HttpRequest and aws_smithy_runtime_api::client::orchestrator::HttpResponse are now re-exported in generated clients so that using these types does not require directly depending on aws-smithy-runtime-api.

July 9th, 2024

Breaking Changes:

• ⚠️ (server, smithy-rs#3746) FromParts<Protocol>::Rejection must implement std::fmt::Display.

  Handlers can accept user-defined types if they implement
  FromParts with a Rejection
  type that implements std::fmt::Display (preferably std::error::Error) to enable error logging when parameter construction from request parts fails.

  See the changelog discussion for futher details.

New this release:

• (client, smithy-rs#3742) Support stringArray type in endpoints params
• 🐛 (client, smithy-rs#3744) Fix bug where stalled stream protection would panic with an underflow if the first event was logged too soon.
