  • v3.0.0-alpha.2

    July 17, 2020

    Highlights

    ๐Ÿš€ The main highlight of this second 3.0.0 alpha release is the introduction of tree shaking. When using a bundler, such as Rollup or Webpack, the bundler can now remove unused charts, scales, and plugins from your code to result in a smaller bundle being delivered to the end user.

    ๐Ÿ’ฅ Breaking Changes

    ๐Ÿš€ There are many breaking changes in this release of Chart.js in addition to those introduce in the previous 3.0.0-alpha release. Most will not be noticeable to users as they are in the internals of the chart, or at points where plugins & scales interface with the chart. However, there are changes to the config option format in v3 that will affect all users of Chart.js. Most noticeably, in all alpha releases, scales are no longer specified in an array and instead are specified in an object. The migration guide provides more details on all of the changes made so far.

    ๐Ÿš€ Major breaking changes since the last alpha release include:

    • Dist file renamed from Chart.js to chart.js
    • ๐Ÿ”Œ npm users must register the charts, scales, elements, and plugins they wish to use (#7435)

    ๐Ÿ’ฅ Breaking Changes

    ๐Ÿš€ There are many breaking changes in this release of Chart.js. Most will not be noticeable to users as they are in the internals of the chart, or at points where plugins & scales interface with the chart. However, there are changes to the config option format in v3. Most noticeably, scales are no longer specified in an array and instead are specified in an object. The migration guide provides more details on all of the changes made so far.
