这是Prometheus 3.0的第二个测试版本（beta.1），暂不推荐生产环境使用。本版本主要包含自v3.0.0-beta.0以来的更新，完整更新需结合beta.0和beta.1的变更日志。关键变更包括：正则表达式".“现匹配所有字符以提升性能；holt_winters函数更名为double_exponential_smoothing并移至实验性功能标志下；启用OTLP接收端点的参数调整为–web.enable-otlp-receiver；目标地址端口处理逻辑变更，移除no-default-scrape-port标志；日志格式调整并采用结构化日志。功能增强涵盖UI多项修复与新增启动/关闭通知、PromQL直方图指数插值、TSDB支持乱序直方图样本摄入、Kubernetes服务发现支持sidecar容器、Consul服务发现支持目录过滤等。性能优化包括并行化数据删除、块编码优化、动态扩展存储结构等。BUG修复涉及指标单位缺失、PromQL直方图处理异常、TSDB数据块冗余字节清理、无效YAML文件自动重载等问题。
