What's Changed

New Features

• Structured Output via ChatSession: ChatSessionOptions now exposes an OutputConfig property, allowing consumers to leverage Bedrock's structured output (JSON schema) feature directly through the chat session API. Previously, structured output was only accessible via the lower-level ConverseBuilder.

Full Changelog

• Plumb OutputConfig through ChatSession.BuildConverseRequest() following the same pattern as ToolConfig and ServiceTier
• Add OutputConfig property to ChatSessionOptions
• Add tests for OutputConfig passthrough behavior

0.7.3-preview

What's Changed

Configurable HTTP Timeout for AWS Service Clients

• Added HttpTimeout property to AwsServiceConfiguration, defaulting to 10 seconds
• Bedrock client overrides to 30 seconds to accommodate longer model inference times
• Timeout is now passed through to the underlying HttpClient via AddGoaService

Structured Output & Strict Tool Support for Bedrock Converse API

• Added OutputConfig models for JSON schema structured output (OutputConfig, OutputFormat, OutputFormatStructure, JsonSchemaDefinition)
• Added WithJsonSchemaOutput builder methods (string and JsonElement overloads) for constraining model output to a JSON schema
• Added WithStrictTool builder method for tools with strict schema enforcement
• Added Strict property to ToolSpec
• Registered new types in BedrockJsonContext for AOT-compatible serialization

Model Switching & ServiceTier Support for Chat Sessions

• Added ModelId property and ChangeModelAsync method to IChatSession for changing the model mid-conversation
• Conversation history is preserved across model changes
• Persistence metadata is updated atomically — _modelId is only set after a successful store update
• Added ServiceTier option to ChatSessionOptions for priority routing

Lambda Bootstrapper Resilience & Graceful Shutdown

• Changed the long-polling /invocation/next HTTP client to use infinite timeout, matching AWS RuntimeSupport behaviour for surviving Lambda freeze/thaw cycles
• Added per-request 30-second timeouts for error reporting and response sending
• Properly propagate external cancellation for graceful shutdown instead of swallowing OperationCanceledException
• Removed unnecessary connection pool settings for the localhost-only Lambda Runtime API client
