rangeRoundBands is deprecated in v4?

On https://square.github.io/intro-to-d3/data-binding/ there is a code section 

```
var y = d3.scaleOrdinal()
  .rangeRoundBands([0, 75])
  .domain(sales.map(function(d, i) {
    return d.product;
  }));
```

It looks like `rangeRoundBands` was removed in v4?
