-    Go 1.17 is not yet released. These are work-in-progress
-    release notes. Go 1.17 is expected to be released in August 2021.
-  </strong>
+  The latest Go release, version 1.17, arrives six months after <a href="/doc/go1.16">Go 1.16</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">promise of compatibility</a>.
+  We expect almost all Go programs to continue to compile and run as before.
