LiteLLM v1.104.6：更换镜像签名密钥并修复多项计费与流式问题
原标题：v1.104.6
AI 摘要
LiteLLM 发布 v1.104.6，共包含 17 个 PR。本次发布最需要关注的变化是：Docker 镜像和 Helm chart 的签名 cosign 密钥已更换，使用旧密钥验证会失败，因此需要更新 CI 校验和 Kyverno 等准入策略。此外，该版本还修复了 Azure AI Foundry 的 400 错误、gpt-5.4+ 工具调用落在 choices[1]、Bedrock/Vertex 流式响应卡住、DeepSeek 与 Qwen3.5 的 token 计数偏差，以及多项成本追踪计费错误。
