LangChain shipped langchain-core 1.6.3 with tracing metadata that now reflects the model and provider a gateway actually runs, and OpenHands added per-profile MCP server scoping so an agent can be restricted from servers that make changes.

langchain-core 1.6.3 is out [1]. The release includes a change that lets clientside tracing metadata for model name and provider be overridden from the gateway response [2]. With custom configs, the model and provider the gateway actually runs differ from what the client requested; the new behavior reconciles the trace with what was executed. The same release also refreshes automated model profile data, adding 10 profiles, removing 0, and changing 13 across 4 providers, including `deepseek-flash` at 1,000,000 context and 384,000 output with text+image input, reasoning, and tools [3].

OpenHands shipped v1.18.0 [4] alongside a change that scopes an agent profile to specific MCP servers [5]. Previously the editor never wrote `mcp_server_refs`, so every profile reached every MCP server a user had configured, including servers that can make changes. The profile picker now supports restriction, which the PR ties to a "Code Exploration agent I trust not to edit anything" goal. A separate fix removes the misleading "No budget limit" line from the Token Usage panel, since no way exists for a user to set `max_budget_per_task` [6].

Cline landed two desktop items. The composer provider picker now lists Cline Pass and gains a set-up row [7]; the underlying constraint is that the picker only lists providers with a saved `providers.json` entry, derived from `enabled = Boolean(directSettings)` in `listLocalProviders`. Cloud session foundations also landed, covering authenticated remote Hub connections and recovery of pending session approvals scoped to attached clients [8]. A separate fix corrects OpenCode Go session headers and model API routing: requests now carry a stable conversation ID and use the API protocol declared for the selected model, addressing the reported `Request is missing x-opencode-session and cannot be routed efficiently` failure [9].

LlamaIndex fixed Gemini tool request IDs [10]. `GoogleGenAI.get_tool_calls_from_response()` had discarded the unique per-call ID returned by Gemini and used the tool name as `ToolSelection.tool_id` instead, a behavior present with `llama-index-core==0.14.7`, `llama-index-llms-google-genai==0.8.7`, and `google-genai==1.63.0`. The reporter found it while debugging tool-context updates in a voice AI agent workflow using Gemini LLMs.
