Breaking Changes:

• ⚠ (all, smithy-rs#2611) Update MSRV to Rust 1.67.1

New this release:

• 🎉 (server, smithy-rs#2540) Implement layer for servers to handle ALB health checks.
  Take a look at aws_smithy_http_server::plugin::alb_health_check to learn about it.
• 🎉 (client, smithy-rs#2254, @eduardomourar) Clients now compile for the wasm32-unknown-unknown and wasm32-wasi targets when no default features are enabled. WebAssembly is not officially supported yet, but this is a great first step towards it!
• (server, smithy-rs#2540) Implement PluginPipeline::http_layer which allows you to apply a tower::Layer to all operations.
• (client, aws-sdk-rust#784, @abusch) Implement std::error::Error#source() properly for the service meta Error enum.
• 🐛 (all, smithy-rs#2496) The outputs for event stream operations now implement the Sync auto-trait.
• 🐛 (all, smithy-rs#2495) Streaming operations now emit the request ID at the debug log level like their non-streaming counterparts.
• 🐛 (client, smithy-rs#2495) Streaming operations now emit the request ID at the debug log level like their non-streaming counterparts.
• (client, smithy-rs#2507) The enableNewCrateOrganizationScheme codegen flag has been removed. If you opted out of the new crate organization scheme, it must be adopted now in order to upgrade (see the upgrade guidance from March 23rd's release).
• (client, smithy-rs#2534) aws_smithy_types::date_time::Format has been re-exported in service client crates.
• 🐛 (server, smithy-rs#2582, smithy-rs#2585) Fix generation of constrained shapes reaching @sensitive shapes
• 🐛 (server, smithy-rs#2583, smithy-rs#2584) Fix server code generation bug affecting constrained shapes bound with @httpPayload
• (client, smithy-rs#2603) Add a sensitive method to ParseHttpResponse. When this returns true, logging of the HTTP response body will be suppressed.
