Hi, We just finished the developing and testing of 4.5.0. Will start the release vote soon.
Here is the draft of changelog https://github.com/apache/incubator-echarts-doc/blob/master/en/changelog.md#v450 Also we will start adding the pull request link and author related to each change in the changelog from this version. I think it will make developers much easier to track each change. And may have more willings to contribute. Regards.
