Langchain v0.1 – Updating GraphAcademy Neo4j & LLM Courses

Langchain v0.1 has been released with significant changes that introduce a new structure for the core, making it leaner and more concise. This update includes changes to how LLM integrations and community tools are organized, as well as deprecations of certain methods and classes. The API has also been standardized through the use of invoke instead of the deprecated __call__ method, and parameters should now be passed as a dictionary through the invoke method. Additionally, the process of creating and working with agents has been updated, requiring a 3-step process that includes creating an agent prompt, creating an agent, and creating an agent executor. These changes offer greater flexibility and improved dependency management, making Langchain v0.1 an important update for users looking to integrate LLMs alongside Neo4j.
