Redux-React Basic Tutorial issues

Not quiet sure where else to put this.

For the Basic Tutorial https://react-redux.js.org/introduction/basic-tutorial there are 3 issues.

Issue 1: The Sandbox Code: https://codesandbox.io/s/6vwyqrpqk3 uses react: 16.4.2, but needs at least 16.8.4 because of .memo()

Issue 2: The tutorial implements the connection for the VisibilityFilters, but it omits setting the filters const VisibilityFilters = ({ activeFilter, setFilter }) => {

<span
key={`visibility-filter-${currentFilter}`}
className={cx(
  "filter",
  currentFilter === activeFilter && "filter--active"
)}
onClick={() => {} /** waiting for setFilter handler*/} <------this should be mentioned in the Tutorial, or filled in
>
{currentFilter}
</span>

Issue 3: Similar to issue 2, the tutorial doesnt implement the toggleTodo() in Todo.js.

Thanks!
