Understand it, then run it
Go 1.25.2 was released on 2025‑10‑07. It contains a set of security fixes for several standard packages: archive/tar, crypto/tls, crypto/x509, encoding/asn1, encoding/pem, net/http, net/mail, net/textproto, and net/url. In addition, the release includes bug fixes for the compiler, runtime, context, debug/pe, os, and sync/atomic. These changes do not add new language features or APIs; they simply patch existing code to make it safer and more reliable.
Run it now
// This program demonstrates that Go 1.25.2 does not introduce new APIs.
// It simply prints a message confirming the absence of changes to the language.
package main
import "fmt"
func main() {
fmt.Println("go1.25.2 has no new API to showcase.")
}
What it printed when we ran it on Go 1.27.1
go1.25.2 has no new API to showcase.
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.
