Version 0.2.2 introduces breaking changes

With Version 0.2.2 the `StackedColumnConfig` is no longer found. As well as the `StackedColumn` in general seems to be gone. From the history and change tracker it seems that the idea is to use just the `Column` and the `ColumnConfig`. But so far I haven't found what the idea is to recreate the connected area again?

Also in case of release management I was pretty suprised to find such a change in a patch version update. I would suggest for future updates to go with semantic versioning. In that case that would have meant to increase the major version.
