[DEPRECATED] Anima2D - Advanced 2D Skeletal Animation Plugin

Is Anima2D dead?

Broken Anima2D features in every latest Unity version, no forum posts from Sergi in over a month, no update to the Asset Store plugin since April, and the latest comment there says it’s not being developed anymore: https://www.assetstore.unity3d.com/en/#!/content/79840

Also no news on Unity’s own 2D skeletal animation system which has been in development for quite some time: Bringing Anima2D to Unity

What’s going on?
