 *This document covers only major changes. For minor and patch changes, please see the [release notes](https://github.com/d3/d3/releases).*
 
+D3 6.0 introduces several non-backwards-compatible changes.
+
+**Adoption of ES2015**
+
+* *All* the D3 modules have now adopted ES2015. Developers who need to maintain compatibility with older browsers will use transpilation. [[details](https://observablehq.com/d/f91cccf0cad5e9cb#es2015)]
+
+**d3-selection** has a new event manager:
+
+* d3.event ⇨ (event) passed as the first argument to all listeners  [[details](https://observablehq.com/d/f91cccf0cad5e9cb#events)]
+* d3.mouse, d3.touch, d3.touches, d3.clientPoint ⇨ d3.pointer [[details](https://observablehq.com/d/f91cccf0cad5e9cb#pointer)]
+
+**d3-brush**, **d3-drag** and **d3-zoom** also use the new event manager:
+
+* *brush*.on listeners now receive event [[details](https://observablehq.com/d/f91cccf0cad5e9cb#event_brush)]
+* *drag*.on listeners now receive event [[details](https://observablehq.com/d/f91cccf0cad5e9cb#event_drag)]
+* *zoom*.on listeners now receive event [[details](https://observablehq.com/d/f91cccf0cad5e9cb#event_zoom)]
+
+**d3-voronoi** is deprecated, and replaced by [d3-delaunay](https://github.com/d3/d3-delaunay):
+
+* d3.voronoi ⇨ d3.Delaunay  [[details](https://observablehq.com/d/f91cccf0cad5e9cb#delaunay)]
+
+**d3-collection** is deprecated, and its methods are replaced:
+
+* d3.nest ⇨ d3.group and d3.rollup (from d3-array)  [[details](https://observablehq.com/d/f91cccf0cad5e9cb#group)]
+* d3.map ⇨ Map [[details](https://observablehq.com/d/f91cccf0cad5e9cb#collection)]
+* d3.set ⇨ Set [[details](https://observablehq.com/d/f91cccf0cad5e9cb#collection)]
+* d3.keys ⇨ Object.keys [[details](https://observablehq.com/d/f91cccf0cad5e9cb#collection)]
+* d3.values ⇨ Object.values [[details](https://observablehq.com/d/f91cccf0cad5e9cb#collection)]
+* d3.entries ⇨ Object.entries [[details](https://observablehq.com/d/f91cccf0cad5e9cb#collection)]
+
+**d3-array** has renamed two methods:
+* d3.histogram ⇨ d3.bin [[details](https://observablehq.com/d/f91cccf0cad5e9cb#bin)]
+* d3.scan ⇨ d3.leastIndex [[details](https://observablehq.com/d/f91cccf0cad5e9cb#leastIndex)]
+
+**d3-interpolate** has a breaking change in an ancillary method:
+* d3.interpolateTransformCss is now stricter in its inputs. [[details](https://observablehq.com/d/f91cccf0cad5e9cb#interpolateTransformCss)]
+
+**d3-format** changes its minus sign:
+* The default symbol for the sign of negative values becomes unicode minus instead of hyphen-minus. [[details](https://observablehq.com/d/f91cccf0cad5e9cb#minus)]
+
+**bower**
+
+Support for the [bower](https://github.com/mbostock-bower/d3-bower) package manager has been dropped; use [unpkg](https://unpkg.com/d3) or [cdnjs](https://cdnjs.com/libraries/d3).

+# Changes in D3 5.0
+
+[Released March 22, 2018.](https://github.com/d3/d3/releases/tag/v5.0.0)
+
 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). (See this [introduction to promises](https://observablehq.com/@observablehq/introduction-to-promises) on [Observable](https://observablehq.com).) For example, to load a CSV file in v4, you might say:

 If you use npm, `npm install d3`. Otherwise, download the [latest release](https://github.com/d3/d3/releases/latest). The released bundle supports anonymous AMD, CommonJS, and vanilla environments. You can load directly from [d3js.org](https://d3js.org), [CDNJS](https://cdnjs.com/libraries/d3), or [unpkg](https://unpkg.com/d3/). For example:
 
 ```html
-<script src="https://d3js.org/d3.v5.js"></script>
+<script src="https://d3js.org/d3.v6.js"></script>
 ```
 
 For the minified version:
 
 ```html
-<script src="https://d3js.org/d3.v5.min.js"></script>
+<script src="https://d3js.org/d3.v6.min.js"></script>
 ```
 
 You can also use the standalone D3 microlibraries. For example, [d3-selection](https://github.com/d3/d3-selection):
 
 ```html
-<script src="https://d3js.org/d3-selection.v1.js"></script>

 D3 is written using [ES2015 modules](http://www.2ality.com/2014/09/es6-modules-final.html). Create a [custom bundle using Rollup](https://bl.ocks.org/mbostock/bb09af4c39c79cffcde4), Webpack, or your preferred bundler. To import D3 into an ES2015 application, either import specific symbols from specific D3 modules:

 You can also require individual modules and combine them into a `d3` object using [Object.assign](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/assign):
 
 ```js
