Go 1.19.1 发布了：看看要不要升级！！！

点击上方蓝色“Go语言中文网”关注，每天一起学 Go

大家好，Go 官方发布了 Go1.19.1 和 Go1.18.6，这是两个小版本，主要包括安全更新和一些 bug 修复，这次一共修复了 20 个 issue。

首先是两个安全更新：

• net/http 包：handle server errors after sending GOAWAY

  A closing HTTP/2 server connection could hang forever waiting for a clean shutdown that was preempted by a subsequent fatal error. This failure mode could be exploited to cause a denial of service.

• net/url 包：JoinPath does not strip relative path components in all circumstances

  JoinPath and URL.JoinPath would not remove ../ path components appended to a relative path. For example, JoinPath("https://go.dev", "../go") returned the URL https://go.dev/../go, despite the JoinPath documentation stating that ../ path elements are cleaned from the result.

其他的 issue 列表见：https://github.com/golang/go/issues?q=milestone%3AGo1.19.1+label%3ACherryPickApproved，文末点击「阅读原文」可以直达该页面。
