You may wish to [exclude moment](../../getting-started/integration.md) and choose from [other available adapters](https://github.com/chartjs/awesome#adapters) instead.

 Chart.js 3.0 introduces a number of breaking changes. Chart.js 2.0 was released in April 2016. In the years since then, as Chart.js has grown in popularity and feature set, we've learned some lessons about how to better create a charting library. In order to improve performance, offer new features, and improve maintainability it was necessary to break backwards compatibility, but we aimed to do so only when necessary.
 
-## Setup

-Chart.js is no longer providing the `Chart.bundle.js` and `Chart.bundle.min.js`. Please see the [installation](installation.md) and [integration](integration.md) docs for details on the recommended way to setup Chart.js if you were using these builds.

+* `moment` is no longer specified as an npm dependency. If you are using the time scale, you must include one of [the available adapters](https://github.com/chartjs/awesome#adapters) and corresponding date library. If you are using a date library other than moment, you no longer need to exclude moment from your build.

 ### Ticks
 
 * `options.ticks.userCallback` was renamed to `options.ticks.callback`
