⚠ (smithy-rs#1144) Some APIs required that timeout configuration be specified with an aws_smithy_client::timeout::Settings struct while
others required an aws_smithy_types::timeout::TimeoutConfig struct. Both were equivalent. Now aws_smithy_types::timeout::TimeoutConfig
is used everywhere and aws_smithy_client::timeout::Settings has been removed. Here's how to migrate code your code that
depended on timeout::Settings:
The old way:
let timeout = timeout::Settings::new()
.with_connect_timeout(Duration::from_secs(1))
.with_read_timeout(Duration::from_secs(2));
The new way:
// This example is passing values, so they're wrapped in `Option::Some`. You can disable a timeout by passing `None`.
let timeout = TimeoutConfig::new()
.with_connect_timeout(Some(Duration::from_secs(1)))
.with_read_timeout(Some(Duration::from_secs(2)));
⚠ (smithy-rs#1085) Moved the following re-exports into a types module for all services:
<service>::AggregatedBytes -> <service>::types::AggregatedBytes<service>::Blob -> <service>::types::Blob<service>::ByteStream -> <service>::types::ByteStream<service>::DateTime -> <service>::types::DateTime<service>::SdkError -> <service>::types::SdkError⚠ (smithy-rs#1085) AggregatedBytes and ByteStream are now only re-exported if the service has streaming operations,
and Blob/DateTime are only re-exported if the service uses them.
⚠ (smithy-rs#1130) MSRV increased from 1.54 to 1.56.1 per our 2-behind MSRV policy.
New this release:
MakeConnectorFn, HttpConnector, and HttpSettings have been moved from aws_config::provider_config to
aws_smithy_client::http_connector. This is in preparation for a later update that will change how connectors are
created and configured.Document shape parser generationClient and Config re-exports now have their documentation inlined in the service docs(smithy-rs#1087) Improve docs on Endpoint::{mutable, immutable}

🐛 (smithy-rs#1054, aws-sdk-rust#391) Fix critical paginator bug where an empty outputToken lead to a never ending stream.
New this release:
⚠ (smithy-rs#990) Codegen will no longer produce builders and clients with methods that take impl Into except for strings and boxed types.
Breaking Changes:
impl Into<T> except for strings and boxed types.aws_smithy_protocol_test::validate_headers was made more flexible but may require adjusting invocations slightly.New this release:
.into_paginator() and (when supported) .into_paginator().items() to enable paginating responses automatically.
