I would like to suggest that releases with changelog are added as a GitHub release, this makes it easier to follow your project.
A few perspectives:
When considering a lib, I always check for last commit date and last releases date to determine viability of project. Right now Konva is misrepresented as last release in 2018.
I have pinned versions on most important libaries i use, inkluding Konva, and need to manually detect and apply updates. I do use npm to apply the updates thou, not the GitHub releases themselves.
I use GitHub dashboard to pay attention to new releases for libaries i use, its a great way to do so!
