Langchain released a first-party MCP adapter, Cline patched four CVEs and fixed telemetry in minified builds, and OpenHands added a runtime telemetry opt-out.

Langchain released langchain==1.4.0a2, an alpha preview that turns any MCP server into LangChain tools via `MCPAdapter` [1]. The adapter builds on FastMCP's client, so transport is inferred and connection handling inherits FastMCP's features. Install with `pip install "langchain[mcp]==1.4.0a2"`. Cline fixed a bug where Langfuse tracer detection always returned false in minified release builds, breaking telemetry in production CLI sessions [2]. The pin was the constructor-name guard in `initializeLangfuseTelemetry`, which fails after minification. Cline also bumped dependencies to address four CVEs in mermaid, all from a single upstream PR patched in 11.16.1 [3]. The sweep covers four packages across the bun workspace and npm-managed subprojects. Cline now loads the live model catalog for both `cline` and `cline-pass`, so the Cline provider can surface newly published models [4], and regenerated its built-in model list so the gateway correctly routes GLM as reasoning-capable [5]. OpenHands added a `--disable-telemetry` runtime flag for the self-hosted canvas, letting deployments opt out without rebuilding with `VITE_DO_NOT_TRACK` [6]. A chat fix re-derives the active profile stamp from event history on reload, with 64/64 tests passing [7].
