==================

**Breaking Changes:**

- ⚠ (server, [smithy-rs#2161](https://github.com/awslabs/smithy-rs/issues/2161)) Remove deprecated service builder, this includes:

    - Remove `aws_smithy_http_server::routing::Router` and `aws_smithy_http_server::request::RequestParts`.

    - Move the `aws_smithy_http_server::routers::Router` trait and `aws_smithy_http_server::routing::RoutingService` into `aws_smithy_http_server::routing`.

    - Remove the following from the generated SDK:

        - `operation_registry.rs`

        - `operation_handler.rs`

        - `server_operation_handler_trait.rs`

    If migration to the new service builder API has not already been completed a brief summary of required changes can be seen in [previous release notes](https://github.com/awslabs/smithy-rs/releases/tag/release-2022-12-12) and in API documentation of the root crate.

**New this release:**

- 🐛 (server, [smithy-rs#2213](https://github.com/awslabs/smithy-rs/issues/2213)) `@sparse` list shapes and map shapes with constraint traits and with constrained members are now supported

- (all, [smithy-rs#2223](https://github.com/awslabs/smithy-rs/issues/2223)) `aws_smithy_types::date_time::DateTime`, `aws_smithy_types::Blob` now implement the `Eq` and `Hash` traits

- (server, [smithy-rs#2223](https://github.com/awslabs/smithy-rs/issues/2223)) Code-generated types for server SDKs now implement the `Eq` and `Hash` traits when possible

Improve SDK credentials caching through type safety. `LazyCachingCredentialsProvider` has been renamed to `LazyCredentialsCache` and is no longer treated as a credentials provider. Furthermore, you do not create a `LazyCredentialsCache` directly, and instead you interact with `CredentialsCache`. This introduces the following breaking changes.

If you previously used `LazyCachingCredentialsProvider`, you can replace it with `CredentialsCache`.

<details>

<summary>Example</summary>

Before:

```rust

use aws_config::meta::credentials::lazy_caching::LazyCachingCredentialsProvider;

use aws_types::provider::ProvideCredentials;

fn make_provider() -> impl ProvideCredentials {

    // --snip--

}

let credentials_provider =

    LazyCachingCredentialsProvider::builder()

        .load(make_provider())

        .build();

let sdk_config = aws_config::from_env()

    .credentials_provider(credentials_provider)

    .load()

    .await;

let client = aws_sdk_s3::Client::new(&sdk_config);

```

After:

```rust

use aws_credential_types::cache::CredentialsCache;

use aws_types::provider::ProvideCredentials;

fn make_provider() -> impl ProvideCredentials {

    // --snip--

}

// Wrapping a result of `make_provider` in `LazyCredentialsCache` is done automatically.

let sdk_config = aws_config::from_env()

    .credentials_cache(CredentialsCache::lazy()) // This line can be omitted because it is on by default.

    .credentials_provider(make_provider())

    .load()

    .await;

let client = aws_sdk_s3::Client::new(&sdk_config);

```

If you previously configured a `LazyCachingCredentialsProvider`, you can use the builder for `LazyCredentialsCache` instead.

Before:

```rust

use aws_config::meta::credentials::lazy_caching::LazyCachingCredentialsProvider;

use aws_types::provider::ProvideCredentials;

use std::time::Duration;

fn make_provider() -> impl ProvideCredentials {

    // --snip--

}

let credentials_provider =

    LazyCachingCredentialsProvider::builder()

        .load(make_provider())

        .load_timeout(Duration::from_secs(60)) // Configures timeout.

        .build();

let sdk_config = aws_config::from_env()

    .credentials_provider(credentials_provider)

    .load()

    .await;

let client = aws_sdk_s3::Client::new(&sdk_config);

```

After:

```rust

use aws_credential_types::cache::CredentialsCache;

use aws_types::provider::ProvideCredentials;

use std::time::Duration;

fn make_provider() -> impl ProvideCredentials {

    // --snip--

}

let sdk_config = aws_config::from_env()

    .credentials_cache(

        CredentialsCache::lazy_builder()

            .load_timeout(Duration::from_secs(60)) // Configures timeout.

            .into_credentials_cache(),

    )

    .credentials_provider(make_provider())

    .load()

    .await;

let client = aws_sdk_s3::Client::new(&sdk_config);

```

The examples above only demonstrate how to use `credentials_cache` and `credentials_provider` methods on `aws_config::ConfigLoader` but the same code update can be applied when you interact with `aws_types::sdk_config::Builder` or the builder for a service-specific config, e.g. `aws_sdk_s3::config::Builder`.

</details>

If you previously configured a `DefaultCredentialsChain` by calling `load_timeout`, `buffer_time`, or `default_credential_expiration` on its builder, you need to call the same set of methods on the builder for `LazyCredentialsCache` instead.

<details>

<summary>Example</summary>

Before:

```rust

use aws_config::default_provider::credentials::DefaultCredentialsChain;

use std::time::Duration;

let credentials_provider = DefaultCredentialsChain::builder()

    .buffer_time(Duration::from_secs(30))

    .default_credential_expiration(Duration::from_secs(20 * 60))

    .build()

    .await;

let sdk_config = aws_config::from_env()

    .credentials_provider(credentials_provider)

    .load()

    .await;

let client = aws_sdk_s3::Client::new(&sdk_config);

```

After:

```rust

use aws_config::default_provider::credentials::default_provider;

use aws_credential_types::cache::CredentialsCache;

use std::time::Duration;

// Previously used methods no longer exist on the builder for `DefaultCredentialsChain`.

let credentials_provider = default_provider().await;

let sdk_config = aws_config::from_env()

    .credentials_cache(

        CredentialsCache::lazy_builder()

            .buffer_time(Duration::from_secs(30))

            .default_credential_expiration(Duration::from_secs(20 * 60))

            .into_credentials_cache(),

    )

    .credentials_provider(credentials_provider)

    .load()

    .await;

let client = aws_sdk_s3::Client::new(&sdk_config);

```

The introduction of `CredentialsCache` comes with an accompanying type `SharedCredentialsCache`, which we will store in the property bag instead of a `SharedCredentialsProvider`. As a result, `aws_http::auth:set_provider` has been updated to `aws_http::auth::set_credentials_cache`.

    SharedCredentialsProvider::new(credentials),
