+## Introduction to Go 1.25 {#introduction}
 
-**Go 1.25 is not yet released. These are work-in-progress release notes.
-Go 1.25 is expected to be released in August 2025.**
+The latest Go release, version 1.25, arrives in [August 2025](/doc/devel/release#go1.25.0), six months after [Go 1.24](/doc/go1.24).
+Most of its changes are in the implementation of the toolchain, runtime, and libraries.
+As always, the release maintains the Go 1 promise of compatibility.
+We expect almost all Go programs to continue to compile and run as before.
