Change Log

Unreleased

Removed the deprecated unprefixed aliases for generated AWS service clients. Imports such as BedrockRuntimeClient must now use the Async-prefixed name, such as AsyncBedrockRuntimeClient.
Changed all generated AWS clients to use AIOHTTPClient as their default transport, including services configured for HTTP/2 or event streaming. Applications that require the CRT transport, such as those using bidirectional event streams, must install the generated client's awscrt extra and explicitly configure AWSCRTHTTPClient.
Removed the legacy Config class from generated AWS clients in favor of the service-specific, async-resolved Async<SdkId>Config class, such as AsyncBedrockRuntimeConfig. Explicit configuration must now be resolved with await Async<SdkId>Config.resolve(...) before it is passed to the client.

Renamed generated AWS service clients to include Async (e.g. BedrockRuntimeClient is now AsyncBedrockRuntimeClient) to match the Python community convention for async clients. For clients that were already published under the unprefixed name, the old name remains available as a deprecated alias that emits a DeprecationWarning and will be removed in an upcoming release. The unprefixed name will later be reintroduced for synchronous clients.
