[BlackySoul]

Привет! Спасибо за PR 🙂

Мы поддерживаем не только 18 версию реакта, но и 17, а для неё импорты из react-dom валидны. Возможно, в документации будет лучше просто оставить пометку, что в 18 версии нужен другой импорт?

[ernado]

Да, точно, пропустил поддержку 17 версии.

В принципе 18 версия не ломается, так что можно просто подождать, когда дропнете поддержку 17. Как поменять импорты в целом понятно, если что - люди найдут этот PR по поиску и починят ворнинг.

PR пока закрою.
