State	Update 🚀

This version is not covered by your current version range.

Without accepting this pull request your project will work just like it did before. There might be a bunch of new features, fixes and perf improvements that the maintainers worked on for you though.

I recommend you look into these changes and try to get onto the latest version of chart.js.
Given that you have a decent test suite, a passing build is a strong indicator that you can take advantage of these changes by merging the proposed change into your project. Otherwise this branch is a great starting point for you to work on the update.

Do you have any ideas how I could improve these pull requests? Did I report anything you think isn’t right?
Are you unsure about how things are supposed to work?

There is a collection of frequently asked questions and while I’m just a bot, there is a group of people who are happy to teach me new things. Let them know.

Good luck with your project ✨

You rock!

GitHub Release

New Build System

Starting with v2.2.0-rc.1 Chart.js uses a new build system. We no longer include the checked in files (dist folder) in the repository. When a tagged release is made, a build will occur and will be published on NPM automatically. A huge thanks to @simonbrunel for getting this set up and working.

This change means that installing via bower needs to use the bower npm resolver. Detailed instructions can be found in the docs
