D3 5.0 introduces only a few non-backwards-compatible changes. D3 5.0 introduces only a few non-backwards-compatible changes.
D3 now uses [Promises](https://developer.mozilla.org/docs/Web/JavaScript/Guide/Using_promises) instead of asynchronous callbacks to load data. Promises simplify the structure of asynchronous code, especially in modern browsers that support [async and await](https://javascript.info/async-await).

With the adoption of promises, D3 now uses the [Fetch API](https://fetch.spec.whatwg.org/) instead of [XMLHttpRequest](https://developer.mozilla.org/docs/Web/API/XMLHttpRequest): the [d3-request](https://github.com/d3/d3-request) module has been replaced by [d3-fetch](https://github.com/d3/d3-fetch). Fetch supports many powerful new features, such as [streaming responses](https://beta.observablehq.com/@mbostock/streaming-shapefiles). D3 5.0 also deprecates and removes the [d3-queue](https://github.com/d3/d3-queue) module. Use [Promise.all](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise/all) to run a batch of asynchronous tasks in parallel, or a helper library such as [p-queue](https://github.com/sindresorhus/p-queue) to [control concurrency](https://beta.observablehq.com/@mbostock/hello-p-queue).

D3 no longer provides the d3.schemeCategory20* categorical color schemes. These twenty-color schemes were flawed because their grouped design could falsely imply relationships in the data: a shared hue can imply that the encoded data are part of a group (a super-category), while relative lightness can imply order. Instead, D3 now includes [d3-scale-chromatic](https://github.com/d3/d3-scale-chromatic), which implements excellent schemes from ColorBrewer, including [categorical](https://github.com/d3/d3-scale-chromatic/blob/master/README.md#categorical), [diverging](https://github.com/d3/d3-scale-chromatic/blob/master/README.md#diverging), [sequential single-hue](https://github.com/d3/d3-scale-chromatic/blob/master/README.md#sequential-single-hue) and [sequential multi-hue](https://github.com/d3/d3-scale-chromatic/blob/master/README.md#sequential-multi-hue) schemes. These schemes are available in both discrete and continuous variants. D3 no longer provides the d3.schemeCategory20* categorical color schemes.

These schemes are available in both discrete and continuous variants.
D3 now provides implementations of [marching squares](https://beta.observablehq.com/@mbostock/d3-contour-plot) and [density estimation](https://beta.observablehq.com/@mbostock/d3-density-contours) via [d3-contour](https://github.com/d3/d3-contour)! There are two new [d3-selection](https://github.com/d3/d3-selection) methods: [*selection*.clone](https://github.com/d3/d3-selection/blob/master/README.md#selection_clone) for inserting clones of the selected nodes, and [d3.create](https://github.com/d3/d3-selection/blob/master/README.md#create) for creating detached elements. [Geographic projections](https://github.com/d3/d3-geo) now support [*projection*.angle](https://github.com/d3/d3-geo/blob/master/README.md#projection_angle), which has enabled several fantastic new [polyhedral projections](https://github.com/d3/d3-geo-polygon) by Philippe Rivière.

Lastly, D3’s [package.json](https://github.com/d3/d3/blob/master/package.json) no longer pins exact versions of the dependent D3 modules. This fixes an issue with [duplicate installs](https://github.com/d3/d3/issues/3256) of D3 modules.

The method signature for optional accessors has been changed to be more consistent with array methods such as [*array*.forEach](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/forEach): the accessor is passed the current element (*d*), the index (*i*), and the array (*data*), with *this* as undefined.

The [d3.quantile](https://github.com/d3/d3-array/blob/master/README.md#quantile) method previously did not take an accessor. Some methods with optional arguments now treat those arguments as missing if they are null or undefined, rather than strictly checking arguments.length.

The new [d3.histogram](https://github.com/d3/d3-array/blob/master/README.md#histograms) API replaces d3.layout.histogram. Rather than exposing *bin*.x and *bin*.dx on each returned bin, the histogram exposes *bin*.x0 and *bin*.x1, guaranteeing that *bin*.x0 is exactly equal to *bin*.x1 on the preceeding bin. The “frequency” and “probability” modes are no longer supported; each bin is simply an array of elements from the input data, so *bin*.length is equal to D3 3.x’s *bin*.y in frequency mode. To compute a probability distribution, divide the number of elements in each bin by the total number of elements. The new [d3.histogram](https://github.com/d3/d3-array/blob/master/README.md#histograms) API replaces d3.layout.histogram. Rather than exposing *bin*.x and *bin*.dx on each returned bin, the histogram exposes *bin*.x0 and *bin*.x1, guaranteeing that *bin*.x0 is exactly equal to *bin*.x1 on the preceding bin.

To compute a probability distribution, divide the number of elements in each bin by the total number of elements.
The *histogram*.range method has been renamed [*histogram*.domain](https://github.com/d3/d3-array/blob/master/README.md#histogram_domain) for consistency with scales. The *histogram*.bins method has been renamed [*histogram*.thresholds](https://github.com/d3/d3-array/blob/master/README.md#histogram_thresholds), and no longer accepts an upper value: *n* thresholds will produce *n* + 1 bins. If you specify a desired number of bins rather than thresholds, d3.histogram now uses [d3.ticks](https://github.com/d3/d3-array/blob/master/README.md#ticks) to compute nice bin thresholds. In addition to the default Sturges’ formula, D3 now implements the [Freedman-Diaconis rule](https://github.com/d3/d3-array/blob/master/README.md#thresholdFreedmanDiaconis) and [Scott’s normal reference rule](https://github.com/d3/d3-array/blob/master/README.md#thresholdScott).

[Sequential scales](https://github.com/d3/d3-scale/blob/master/README.md#scaleSequential), are a new class of scales with a fixed output [interpolator](https://github.com/d3/d3-scale/blob/master/README.md#sequential_interpolator) instead of a [range](https://github.com/d3/d3-scale/blob/master/README.md#continuous_range).
