LangChain ships Managed Deep Agents 0.10 with browser use and async subagents

LangChain released Managed Deep Agents v0.10. Founder Harrison Chase argues many harness-engineering challenges are now best solved by tighter integration of harness and infra, with async subagents and browser use as prime examples.
- Browser use: most of the web has no API, just pages built for humans — agents can now operate a browser directly. When a site requires login, agents can hand over the window so passwords stay out of the model
- Async subagents: long-running tasks execute in the background while the main agent keeps working
Both are built into every MDA deployment.
