Today the Go team is excited to release Go 1.24, which you can get by visiting the download page.

​ 今天，Go 团队很高兴发布 Go 1.24，您可以通过访问 下载页面 获取。

Go 1.24 comes with many improvements over Go 1.23. Here are some of the notable changes; for the full list, refer to the release notes.

​ Go 1.24 相较于 Go 1.23 有许多改进。以下是一些显著变化；完整列表请参阅 发布说明.

语言变化 Language changes

Go 1.24 now fully supports generic type aliases: a type alias may be parameterized like a defined type. See the language spec for details.

​ Go 1.24 现已完全支持 泛型类型别名：类型别名可以像定义类型那样带参数。详细信息请参阅 语言规范.

性能改进 Performance improvements

Several performance improvements in the runtime have decreased CPU overhead by 2–3% on average across a suite of representative benchmarks. These improvements include a new builtin map implementation based on Swiss Tables, more efficient memory allocation of small objects, and a new runtime-internal mutex implementation.

​ 运行时的几项性能改进使得在一系列代表性基准测试中，CPU 开销平均降低了 2–3%。这些改进包括基于 Swiss Tables 的全新内置 map 实现、更高效的小对象内存分配，以及全新的运行时内部互斥锁实现.

工具改进 Tool improvements

• The go command now provides a mechanism for tracking tool dependencies for a module. Use go get -tool to add a tool directive to the current module. Use go tool [tool name] to run the tools declared with the tool directive. Read more on the go command in the release notes.
• go 命令现在提供了一种跟踪模块工具依赖的机制。使用 go get -tool 为当前模块添加 tool 指令，使用 go tool [tool name] 来运行通过 tool 指令声明的工具。更多信息请阅读发布说明中的 go 命令.
• The new test analyzer in go vet subcommand reports common mistakes in declarations of tests, fuzzers, benchmarks, and examples in test packages. Read more on vet in the release notes.
• go vet 子命令中的新 test 分析器会报告测试包中测试、模糊测试、基准测试和示例声明中的常见错误。更多信息请阅读发布说明中的 vet.

标准库新增内容 Standard library additions

• The standard library now includes a new set of mechanisms to facilitate FIPS 140-3 compliance. Applications require no source code changes to use the new mechanisms for approved algorithms. Read more on FIPS 140-3 compliance in the release notes. Apart from FIPS 140, several packages that were previously in the x/crypto module are now available in the standard library.
• 标准库现新增了一套 促进 FIPS 140-3 合规性的机制。使用这些新机制支持已批准的算法，无需修改源代码。更多信息请阅读发布说明中的 FIPS 140-3 合规性。此外，之前位于 x/crypto 模块中的几个包现在已可在 标准库 中使用.
• Benchmarks may now use the faster and less error-prone testing.B.Loop method to perform benchmark iterations like for b.Loop() { ... } in place of the typical loop structures involving b.N like for range b.N. Read more on the new benchmark function in the release notes.
• 基准测试现在可以使用更快且更不易出错的 testing.B.Loop 方法来执行基准迭代，如 for b.Loop() { ... }，以替代传统涉及 b.N 的循环结构，如 for range b.N。更多信息请阅读发布说明中的 新基准函数.
• The new os.Root type provides the ability to perform filesystem operations isolated under a specific directory. Read more on filesystem access in the release notes.
• 全新的 os.Root 类型提供了在特定目录下执行文件系统操作的能力。更多信息请阅读发布说明中的 文件系统访问.
• The runtime provides a new finalization mechanism, runtime.AddCleanup, that is more flexible, more efficient, and less error-prone than runtime.SetFinalizer. Read more on cleanups in the release notes.
• 运行时提供了全新的清理机制 runtime.AddCleanup，比 runtime.SetFinalizer 更灵活、更高效且不易出错。更多信息请阅读发布说明中的 清理.

改进的 WebAssembly 支持 Improved WebAssembly support

Go 1.24 adds a new go:wasmexport directive for Go programs to export functions to the WebAssembly host, and supports building a Go program as a WASI reactor/library. Read more on WebAssembly in the release notes.

​ Go 1.24 新增了 go:wasmexport 指令，使 Go 程序可以将函数导出到 WebAssembly 宿主，并支持将 Go 程序构建为 WASI 反应器/库。更多信息请阅读发布说明中的 WebAssembly.
