Release2026-09-24

LangChain released Managed Deep Agents 0.8. It adds user-owned credentials for per-user permissions. It adds user-level memory for caller-specific context. It adds HTTP channels for webhook-based agent access. It adds file transfer support in Slack. It includes a pre-built web search tool powered by Parallel. User memory is scoped to the authenticated caller. Agent memory remains shared across users. Default policies prevent user memory leakage in group channels. Connections support 23 services with managed OAuth. Slack workflows now accept files directly in conversations.
