All notable changes to this project will be documented in this file.
This project adheres to [Semantic Versioning](http://semver.org/).
## Not released:
## 7.0.0 - 2020-06-23
* **BREAKING** `inherit` option is removed from `visible` and `listening`. They now just have boolean values `true` or `false`. If you do `group.listening(false);` then whole group and all its children will be removed from the hitGraph (and they will not listen to events). Probably 99% `Konva` applications will be not affected by this *breaking change*.
