\"\"<\/a><\/p>\n

After 6 months of development, Go language announced new 1.24 release few days ago on Tuesday.<\/p>\n

Go 1.24 now fully supports generic type aliases.<\/b> Type aliases, a concept introduced in Go 1.9, allows to create a new name for an existing type without creating a new type. Previously, it didn’t support type parameters. But this changed in Go 1.24. See more about generic type aliases<\/a>.<\/p>\n

\"\"<\/a><\/p>\n

<\/p>\n

The feature is enabled by default in Go 1.24, but can be disabled by setting GOEXPERIMENT=noaliastypeparams<\/code>; though the aliastypeparams<\/code> setting will be removed for next Go 1.25.<\/p>\n

Go command in the release now has a new -tool<\/code> flag for go get<\/code>, allowing to add a tool directive to the current module for named packages. It also added new tests<\/code> analyzer for go vet<\/code> to report common mistakes in declarations of tests, fuzzers, benchmarks, and examples in test packages<\/p>\n

\"\"<\/a><\/p>\n

Go 1.24 now includes a new set of mechanisms to facilitate FIPS 140-3 compliance. The Go Cryptographic Module is a set of standard library to implement FIPS 140-3 approved algorithms. And, applications require no changes to use it for approved algorithms.<\/p>\n

Benchmarks may now use the faster and less error-prone testing.B.Loop<\/code> method to perform benchmark iterations like for b.Loop() { ... }<\/code> in place of the typical loop structures involving b.N<\/code> like for range b.N<\/code>.<\/p>\n

There are as well new os.Root<\/code> type provides the ability to perform filesystem operations within a specific directory, and new runtime.AddCleanup<\/code> finalization mechanism that is more flexible, more efficient, and less error-prone than runtime.SetFinalizer<\/code>.<\/p>\n

Other changes include go:wasmexport<\/code> compiler directive to export functions to the WebAssembly host, as well as:<\/p>\n
