huggingface/transformers — Fixed silent attention scaling bug in GPT-2 affecting SDPA/FlashAttention backends. The bug caused incorrect outputs without any error — the most insidious type of bug. 3-round code review with maintainer. (PR #44397)
openai/openai-agents-python — Fixed RunConfig inheritance chain in agent-as-tool scenarios, ensuring parent tracing/privacy configs propagate to child agent runs. (PR #2463)
openai/openai-agents-python — Fixed voice pipeline trace lifecycle: spans were closed before pipeline processing completed, breaking observability. (PR #2472)
BerriAI/litellm — Filtered
customfield from tool definitions to prevent Bedrock 400 errors. Directly impacted all Claude Code users routing through LiteLLM. (PR #22861)
