Nuno Campos	663747b730	core[patch]: Fixes for convert_messages (#21207) ... - support two-tuples of any sequence type (eg. json.loads never produces tuples) - support type alias for role key - if id is passed in in dict form use it - if tool_calls passed in in dict form use them --------- Co-authored-by: Bagatur <baskaryan@gmail.com>	5 months ago

ccurme	795c728f71	mistral[patch]: add IDs to tool calls (#20299) ...

Leonid Ganeline	8609afbd10	core[patch]: Update `messages` namespace to fix API reference docs (#19161) ... Classes and functions defined in __init__.py are not parsed into the API Reference. For example: - libs/core/langchain_core/messages/__init__.py : AnyMessage, MessageLikeRepresentation, get_buffer_string(), messages_from_dict(), ... Opinionated: __init__.py is not a typical place to define artifacts. Moved artifacts from __init__ into utils.py. Added `MessageLikeRepresentation` to __all__ since it is used outside of `messages`, for example, in `libs/core/langchain_core/language_models/base.py` Added `_message_from_dict` to __all__ since it is used outside of `messages`(???) I would add `message_from_dict` (without underscore) as an alias. Please, advise.	6 months ago

Leonid Ganeline	2f2b77602e	docs: modules descriptions (#17844) ...

Hendrik Hogertz	e6862e6e7d	Fix Azure Openai function calling in streaming mode (#13768) ... - **Description**: This PR addresses an issue with the OpenAI API streaming response, where initially the key (arguments) is provided but the value is None. Subsequently, it updates with {"arguments": "{\n"}, leading to a type inconsistency that causes an exception. The specific error encountered is ValueError: additional_kwargs["arguments"] already exists in this message, but with a different type. This change aims to resolve this inconsistency and ensure smooth API interactions. - **Issue**: None. - **Dependencies**: None. - **Tag maintainer**: @eyurtsev This is an updated version of #13229 based on the refactored code.
