The deepagents‑code 0.1.4 release adds a `--sandbox-snapshot-name` CLI flag, unifies the `dcode mcp config` command with `--mcp-config`, and introduces interpreter middleware via `langchain-quickjs`.

Why it matters: These changes give developers explicit snapshot naming for sandbox testing, streamline MCP configuration handling, and enable custom interpreter workflows through langchain‑quickjs integration.
