Next Release Notes Draft

DRAFT RELEASE NOTES — Introduction to Go 1.26

Go 1.26 is not yet released. These are work-in-progress release notes. Go 1.26 is expected to be released in February 2026.

Tools

Go command

cmd/doc, and go tool doc have been deleted. go doc can be used as a replacement for go tool doc: it takes the same flags and arguments and has the same behavior.

Bootstrap

As mentioned in the Go 1.24 release notes, Go 1.26 now requires Go 1.24.6 or later for bootstrap. We expect that Go 1.28 will require a minor release of Go 1.26 or later for bootstrap.

Standard library

Minor changes to the library

go/types

The Var.Kind method returns an enumeration of type VarKind that classifies the variable (package-level, local, receiver, parameter, result, or struct field). See issue #70250.

Callers of NewVar or NewParam are encouraged to call Var.SetKind to ensure that this attribute is set correctly in all cases.

database/sql/driver

A database driver may implement RowsColumnScanner to entirely override Scan behavior.

net

Added context aware dial functions for TCP, UDP, IP and Unix networks.

net/http/httptest

The HTTP client returned by Server.Client will now redirect requests for example.com and any subdomains to the server being tested.

Ports

Windows

As announced in the Go 1.25 release notes, the broken 32-bit windows/arm port (GOOS=windows GOARCH=arm) is removed.
