主要标签 🏷️

以下是镜像的主要标签。每个提交及其简写sha256值也有对应的标签。

• 3.5.3

没有latest标签，我应该如何处理更新？

我认为:latest标签很危险。很多时候，我对镜像引入了破坏性变更，这可能会给一些人带来麻烦。如果您不想将标签更改为最新的语义化版本，只需使用语义化版本的短版本。不使用:3.5.3，您可以使用:3或:3.5。由于这些标签会在每个新版本中更新为软件的最新版本，使用它们与使用:latest类似，但至少固定在主版本或次版本上。

如果您仍然坚持使用此应用的最新版本，只需使用:rolling标签，但请注意！您将立即获得应用的最新版本，无论是否有破坏性变更或安全问题。风险自负！
