LangChain shipped langchain-openai 1.4.2 with fixes for context window overflows and broken Claude rename operations, while OpenHands v1.11.0 adds per-run LLM cost tracking.

langchain-openai==1.4.2 [1] landed with a critical fix for `ContextWindowExceededError` handling and a repair to the Claude file-tool middleware that was throwing `KeyError` on every rename operation [2]. The same release filtered langchain-generated content block IDs to prevent conflicts with OpenAI's response handling [1]. In the core LangChain repo, the `SummarizationMiddleware` now preserves conversation history on summary failure by retrying transient errors up to 3 times via `Runnable.with_retry` [3], closing a gap where error text could overwrite entire chat threads. The `LLMToolEmulator` import handler [4] now raises actionable errors when `langchain-anthropic` isn't installed, giving teams a migration window before `model` becomes required in a future release. OpenHands v1.11.0 [5] shipped per-run LLM cost visibility in the Activity Log and exports, alongside UI polish for the Agent Canvas and conversation tag filtering [6]. Across 3 repos, this period saw 47 commits, 48 PRs, and 4 releases. On the Cline desktop side, a breaking fix [7] removed Vercel Analytics injection that was crashing webview startup with SyntaxError, while tooling hardening [8] prevents malformed model outputs from crashing the CLI formatter.

Action items

→ Upgrade langchain-openai to 1.4.2 if using Claude file tools or hitting context window errors langchain-ai/langchain [immediate]
→ Update OpenHands to v1.11.0 to enable cost-per-run tracking in production logs OpenHands/OpenHands [plan]
→ Redeploy Cline desktop agents to pick up webview startup fix cline/cline [immediate]
