Doubling down on DeepAgents

LangChain has announced the 0.2 release of DeepAgents, a Python package for building complex, long-running AI agents. The primary new feature is pluggable backends, which create a filesystem abstraction讓 agents to interact with various storage systems like local files or cloud databases. Other improvements include automatic eviction of large tool results to the filesystem and summarization of long conversation histories. The release also clarifies the library's role as an "agent harness" that builds upon the LangChain framework and LangGraph runtime for creating autonomous agents.
