发布日期: 2026-02-13
版本号: v3.4.41

请先查看变更日志了解完整更新内容，并在升级前阅读升级指南，可能存在破坏性变更。安装指南请参考 play.etcd.io 和 etcd 操作文档，各平台支持状态详见“支持的平台”页面。

Linux：下载 v3.4.41 版本压缩包，解压后运行 etcd、etcdctl、etcdutl 验证版本并启动服务，可通过 etcdctl 进行数据读写测试。

macOS：下载对应版本压缩包，解压后验证工具版本。

Docker：使用 gcr.io/etcd-development/etcd:v3.4.41 镜像启动容器，映射 2379 与 2380 端口并挂载数据目录，通过 docker exec 验证服务并进行读写测试。

etcd主要使用gcr.io/etcd-development/etcd作为容器镜像仓库，次要使用quay.io/coreos/etcd。

etcd uses gcr.io/etcd-development/etcd as a primary container registry, and quay.io/coreos/etcd as secondary.
