Breaking Changes:

• ⚠ (client, smithy-rs#2099) The Rust client codegen plugin is now called rust-client-codegen instead of rust-codegen. Be sure to update your smithy-build.json files to refer to the correct plugin name.
• ⚠ (client, smithy-rs#2099) Client codegen plugins need to define a service named software.amazon.smithy.rust.codegen.client.smithy.customize.ClientCodegenDecorator (this is the new file name for the plugin definition in resources/META-INF/services).
• ⚠ (server, smithy-rs#2099) Server codegen plugins need to define a service named software.amazon.smithy.rust.codegen.server.smithy.customize.ServerCodegenDecorator (this is the new file name for the plugin definition in resources/META-INF/services).

New this release:

• 🐛 (server, smithy-rs#2103) In 0.52, @length-constrained collection shapes whose members are not constrained made the server code generator crash. This has been fixed.
• (server, smithy-rs#1879) Servers support the @default trait: models can specify default values. Default values will be automatically supplied when not manually set.
• (server, smithy-rs#2131) The constraint @length on non-streaming blob shapes is supported.
• 🐛 (client, smithy-rs#2150) Fix bug where string default values were not supported for endpoint parameters
• 🐛 (all, smithy-rs#2170, aws-sdk-rust#706) Remove the webpki-roots feature from hyper-rustls
• 🐛 (server, smithy-rs#2054) Servers can generate a unique request ID and use it in their handlers.
