This automated release-watch entry was generated from the project's official GitHub release feed and is kept separate from human-reviewed editorial analysis. Release notes: What Internal hardening of how the browser runtime issues authenticated LLM and Model Gateway requests: they now use a fetch reference captured at startup rather than the ambient global. No public API or behavior change for callers. Changes extension/llm/boundFetch.ts (new) — a fetch reference captured at module load. extension/llm/aiSdkClient.ts — pass boundFetch into the provider connection (OpenAI/Anthropic/Google/Groq/Cerebras). extension/llm/LLMProvider.ts — pass boundFetch into getAISDKLanguageModel 's provider factory. extension/llm/gatewayClient.ts — fetchWithoutModel uses boundFetch ; createGatewayLanguageModel always passes the load-time reference (previously only when no model config). sdk-go embedded extension regenerated; gateway-client test updated to the new contract. Draft — part of an incremental hardening series.","sponsors":[]}
