## DRAFT RELEASE NOTES — Introduction to Go 1.N {#introduction}

**Go 1.N is not yet released. These are work-in-progress release notes.

            We check the binary compatibility by comparing the current code’s binary interfaces
            against THE LATEST VERSION WHICH IS RELEASED FROM RELEASE BRANCH (from `released-version.json` on this branch)
