# MuleSoft AI Chain Connector Release Notes

> For the full documentation index, see: https://docs.mulesoft.com/llms.txt

MuleSoft AI Chain Connector enables developers to design, develop, and manage AI agents from within
Anypoint Platform. It provides the tools and support needed to integrate Large Language Models
(LLMs), vector stores, and other advanced AI services into MuleSoft applications.

Guide: [MuleSoft AI Chain Connector User Guide](https://docs.mulesoft.com/mulesoft-ai-chain-connector/latest/)

## 2.0.0

**September 24, 2026**

### What’s New

- This connector is now compatible with Java 17 only.

- Java classes moved from `org.mule.extension.mulechain` to `com.mulesoft.connectors.mulechain`.
  Update custom Java code that imports the previous package.

- `com.mulesoft.connectors.mulechain.internal.config.LangchainLLMConfiguration.getModel()` now
  returns `dev.langchain4j.model.chat.ChatModel`. In version 1.x,
  `org.mule.extension.mulechain.internal.config.LangchainLLMConfiguration.getModel()` returned
  `dev.langchain4j.model.chat.ChatLanguageModel`.

- You can use tools with Ollama chat models. The embedded LangChain4j engine is upgraded from 0.34.0
  to 1.20.0. For more information, see
  [Tools Use AI Service](https://docs.mulesoft.com/mulesoft-ai-chain-connector/latest/mulesoft-ai-chain-connector-reference#ToolsUseAiService).

- File paths that contain a `..` segment are rejected. A **Configuration Json**
  [File Path](https://docs.mulesoft.com/mulesoft-ai-chain-connector/latest/mulesoft-ai-chain-connector-reference#Config)
  that contains `..` is not loaded. The
  [Image Read Scanned Documents](https://docs.mulesoft.com/mulesoft-ai-chain-connector/latest/mulesoft-ai-chain-connector-reference#ImageReadScannedDocuments)
  **File Path** fails with `MS-AICHAIN:FILE_HANDLING_FAILURE`.

For more information about how to upgrade, see
[Upgrading and Migrating MuleSoft AI Chain Connector to 2.x](https://docs.mulesoft.com/mulesoft-ai-chain-connector/latest/mulesoft-ai-chain-connector-upgrade-migrate).
