(1.2.2) — [release notes](https://github.com/langchain-ai/langchainjs/releases/tag/%40langchain/aws%401.2.2) ### Security - LangChain: MongoDBChatMessageHistory query injection can allow cross-session access (1.3.1) — [security advisory](https://github.com/advisories/GHSA-M6RX-H84Q-8R95) - LangChain: RediSearch Filter Injection via Unescaped Tag/Text Values (1.1.1) — [security advisory](https://github.com/advisories/GHSA-5X6V-P487-7QH2) ### New APIs and options - Accepts additionalModelResponseFieldPaths as a constructor and call option, forwarding it to Converse and ConverseStream. (1.4.7) — [release notes](https://github.com/langchain-ai/langchainjs/releases/tag/%40langchain/aws%401.4.7) - Maps Anthropic's thinking-token count to this field for invoke(), .stream() and streamEvents() when the native usage field is present; output_tokens remains unchanged. (1.4.7) — [release notes](https://github.com/langchain-ai/langchainjs/releases/tag/%40langchain/aws%401.4.7) - Add direct routing for Bedrock Converse and Vertex AI chat models through LANGSMITH_GATEWAY. (1.4.6) — [release notes](https://github.com/langchain-ai/langchainjs/releases/tag/%40langchain/aws%401.4.6) - Bedrock Converse now supports native streamEvents events. (1.4.0) — [release notes](https://github.com/langchain-ai/langchainjs/releases/tag/%40langchain/aws%401.4.0) - Adds defaultHeaders to ChatBedrockConverse. (1.3.3) — [release notes](https://github.com/langchain-ai/langchainjs/releases/tag/%40langchain/aws%401.3.3) - Adds bedrockApiKey, bedrockApiSecret, and bedrockApiSessionToken constructor fields for passing AWS credentials directly, with environment-variable fallbacks; an explicit credentials field retains highest priority. (1.3.2) — [release notes](https://github.com/langchain-ai/langchainjs/releases/tag/%40langchain/aws%401.3.2) - Structured output now supports standard schemas. (1.3.1) — [release notes](https://github.com/langchain-ai/langchainjs/releases/tag/%40langchain/aws%401.3.1) - The Converse API now supports the Priority, Standard, and Flex AWS Bedrock service tiers. (1.2.0) — [release notes](https://github.com/langchain-ai/langchainjs/releases/tag/%40langchain/aws%401.2.0) - Adds support for using a Bedrock Application Inference Profile. (1.1.0) — [release notes](https://github.com/langchain-ai/langchainjs/releases/tag/%40langchain/aws%401.1.0) ### Behavior and default changes - File names are imputed for document content blocks. (1.3.4) — [release notes](https://github.com/langchain-ai/langchainjs/releases/tag/%40langchain/aws%401.3.4) - Input messages support standard multimodal video and audio blocks, converted to Bedrock's native format, and native Bedrock blocks pass through unchanged.

(1.4.5) — [release notes](https://github.com/langchain-ai/langchainjs/releases/tag/%40langchain/aws%401.4.5) - Stream-idle timeout errors now set lc_error_code directly on the error, so a plain error.lc_error_code check can detect them. (1.4.4) — [release notes](https://github.com/langchain-ai/langchainjs/releases/tag/%40langchain/aws%401.4.4) - The streamIdleTimeout watchdog now covers the wait before the initial response, as well as gaps between stream chunks. (1.4.4) — [release notes](https://github.com/langchain-ai/langchainjs/releases/tag/%40langchain/aws%401.4.4) - Standard reasoning blocks preserve signatures; replay omits incomplete signature-only reasoning while retaining compatibility with legacy and redacted Bedrock reasoning.

(1.3.9) — [release notes](https://github.com/langchain-ai/langchainjs/releases/tag/%40langchain/aws%401.3.9) - Preserves Bedrock tool call identity in callback-streamed chunks. (1.3.8) — [release notes](https://github.com/langchain-ai/langchainjs/releases/tag/%40langchain/aws%401.3.8) - Bedrock Converse object errors are normalized for tracing. (1.3.5) — [release notes](https://github.com/langchain-ai/langchainjs/releases/tag/%40langchain/aws%401.3.5) - When aborted, stream() throws a regular AbortError; streaming loops now check abort signals and return early. (1.2.2) — [release notes](https://github.com/langchain-ai/langchainjs/releases/tag/%40langchain/aws%401.2.2) - Cache points in ToolMessage are mapped outside the tool result content block.
