David DeCaprio a4bcb45f65 core:Add optional max_messages to MessagePlaceholder (#16098) ... - **Description:** Add optional max_messages to MessagePlaceholder - **Issue:** [16096](https://github.com/langchain-ai/langchain/issues/16096) - **Dependencies:** None - **Twitter handle:** @davedecaprio Sometimes it's better to limit the history in the prompt itself rather than the memory. This is needed if you want different prompts in the chain to have different history lengths. --------- Co-authored-by: Harrison Chase <hw.chase.17@gmail.com>		3 months ago
