    grep '"tag_name":' |                                            # Get tag line
    sed -E 's/.*"([^"]+)".*/\1/'                                    # Pluck JSON value
}

# Usage
# $ get_latest_release "creationix/nvm"
# v0.31.4

For the gh-cli inclined:

gh release list --exclude-pre-releases --json tagName,isLatest --jq '.[] | select(.isLatest) | .tagName'

@roryabraham also gh CLI, but even shorter:

gh repo view --json latestRelease --jq '.[] | .tagName'
