## DRAFT RELEASE NOTES — Introduction to Go 1.24 {#introduction}

**Go 1.24 is not yet released. These are work-in-progress release notes.

## Linker {#linker}

## Bootstrap {#bootstrap}

<!-- go.dev/issue/64751 -->
As mentioned in the [Go 1.22 release notes](/doc/go1.22#bootstrap), Go 1.24 now requires
Go 1.22.6 or later for bootstrap.

## Ports {#ports}

### Linux {#linux}

As [announced](go1.23#linux) in the Go 1.23 release notes, Go 1.24 requires Linux
kernel version 3.2 or later.

### WebAssembly {#wasm}

and the [go command documentation](/cmd/go#hdr-Build_and_test_caching).

### Go 1.24

Go 1.24 changed the global [`math/rand.Seed`](/pkg/math/rand/#Seed) to be a
no-op. This behavior is controlled by the `randseednop` setting.
For Go 1.24 it defaults to `randseednop=1`.
Using `randseednop=0` reverts to the pre-Go 1.24 behavior.

Go 1.24 added new values for the `multipathtcp` setting.
The possible values for `multipathtcp` are now:

- [CHANGELOG-1.28.md](./CHANGELOG-1.28.md)
- [CHANGELOG-1.27.md](./CHANGELOG-1.27.md)
