Where are the Vaadin Chart release notes?

I’m a bit confused… I see in the Addon directory that the maven plugin shows to use 4.0.4 but in [user manual]
(https://vaadin.com/docs/v10/charts/java-api/charts-installing.html) it says 6.0.0.beta1 but calls it vaadin-charts-flow. What is the difference?

Also where can I find the release notes for Charts itself?

vaadin-charts-flow is for the Flow framework (Vaadin 10+) and vaadin-charts 4.x is for Vaadin Framework 8.
