Understand it, then run it

The Go 1.26.6 release contains security fixes for several core packages, including crypto/tls, encoding/asn1, encoding/xml, html/template, net, net/http, and net/url. It also includes bug fixes for the compiler, linker, runtime, and the os package. The changes do not add new language features or modify existing APIs; they simply patch vulnerabilities and improve stability.

Run it now

Todaygo

// This program demonstrates that Go 1.26.6 contains no new API changes.
// It simply prints a message confirming that the language itself is unchanged.
package main

import "fmt"

func main() {
	fmt.Println("Go 1.26.6 does not introduce new language features.")
}

What it printed when we ran it on Go 1.27.1

Go 1.26.6 does not introduce new language features.

Run sends this program (for Solidity, the contract and its tests) to our own sandbox, where it is compiled and run once, with no network, and what it printed or the test report comes back here. Nothing is kept. Runs are counted per visitor for the day so everyone gets a turn; the details are on the legal page.
