Changelog

New Features:

• Granular control of history messages: Add num_history_messages to control how many messages to consider when getting them from history.
• Update AgentOS instances from lifespan functions: You can know gain access to the contextual AgentOS instance in lifespan functions. This is useful to update anything inside the AgentOS instance after it has already been initialized and run.

Improvements:

• Handle media in dict inputs: Media instances are now supported when providing the input for a run as a dictionary, instead of as a list of Messages.
• Client persistence for all models: All model implementations now cache and reuse their HTTP clients when possible.

Bug Fixes:

• OllamaEmbedder not respecting custom dimensions parameter: Fixed OllamaEmbedder to properly pass the dimensions parameter to the Ollama API during embedding generation.
• Metrics calculation: Fix a problem when persisting metrics calculations when using a model with : in its name.
• Agentic memory deletion: Fix a bug related to user memory deletion when using agentic memory management.
