warn: "options.generator" property is deprecated, use "output.name" instead

index.js#39L

function isEbook(book) {
  // 2.x
  if (book.options && book.options.generator) {
    return book.options.generator === 'ebook';
  }

  // 3.x
  return book.output.name === 'ebook';
}

book.options.generator is a get/set,you could change to

function isEbook(book) {
  // 2.x
  if (/^2+\.\d+\.\d+$/.test(book.gitbook.version)) {
    return book.options.generator === 'ebook';
  }
  return book.output.name === 'ebook';
}
