## Helm 4.0.0：首个稳定版本 Helm 团队发布了 Helm 4.0.0，这是一次重要的版本更新，引入了显著的改进。主要功能包括：重新设计的插件系统，支持 Web Assembly；服务器端应用；增强的资源监控；本地缓存；以及通过 `slog` 改进的日志记录。SDK API 已更新，支持多个图表 API 版本，包括实验性的 v3 版本。虽然在 CLI 标志和输出方面与 v3 不兼容，但团队旨在使过渡比 v2 到 v3 的转变更加平滑。现有的 v2 图表仍然受支持，并且大多数工作流程*应该*继续正常运行。**鼓励测试**以确保兼容性。未来发布计划于 2025 年 12 月 10 日（补丁版本 3.19.3 & 4.0.1）和 2026 年 1 月 21 日（小版本 3.20.0 & 4.1.0）。在此处下载 Helm 4.0.0 并查找安装指南：[https://helm.sh/docs/overview/](https://helm.sh/docs/overview/) 团队对充满活力的社区的贡献和支持表示感谢。

原文

The Helm Team is proud to announce the first stable release of Helm 4.

New Features

Helm 4 has numerous new features, but a few deserve highlighting here:

Redesigned plugin system that supports Web Assembly based plugins
Post-renderers are now plugins
Server side apply is now supported
Improved resource watching, to support waiting, based on kstatus
Local Content-based caching (e.g. for charts)
Logging via slog enabling SDK logging to integrate with modern loggers
Reproducible builds of chart archives
Updated SDK API including support for multiple chart API versions (new experimental v3 chart API version coming soon)

For full release notes, please see: https://helm.sh/docs/overview/

Compatibility with Helm v3

Helm v4 is a major version with backward incompatible changes including to the flags and output of the Helm CLI and to the SDK.

Please evaluate the changes to your workflows. The changes are not as extensive as those from Helm v2 to v3, with the goal that the majority of workflows remain compatible between Helm v3 and v4.

Helm charts apiVersion v2 (majority of today's charts) will continue to be supported in Helm v4. Existing charts should continue to install, upgrade, and otherwise work. Please test the installation and upgrade of charts to ensure it works as expected. Changes (e.g., server side apply) may impact the experience.
