// The SDK version reaches customers through three channels that are edited in
// different places: version.go (rendered from the manifest), the CHANGELOG
// heading, and the git tag. They drifted once already — version.go said
// 12.0.0-rc.1 while the CHANGELOG still announced v12.0.0 — which is the kind
// of mismatch nobody notices until a release is cut against the wrong notes.
//
// These assert the two the SDK can see. The tag is checked at release time.
