-    release notes. Go 1.16 is expected to be released in February 2021.
-  </strong>
+  The latest Go release, version 1.16, arrives six months after <a href="/doc/go1.15">Go 1.15</a>.
+  Most of its changes are in the implementation of the toolchain, runtime, and libraries.
+  As always, the release maintains the Go 1 <a href="/doc/go1compat.html">promise of compatibility</a>.
+  We expect almost all Go programs to continue to compile and run as before.
