What's wrong?

Feels like memory leaks and breaking changes.

I'm not sure what was happen so don't know why you merged these changes but not released them.

Okay, I updated on the latest version and see a lot of errors, but I don't see a correlation between this patch and memory leaks. I suspect that this is due to the update of dependencies, but right now I don't have enough time to solve it, maybe later.
About "released them", I'm not sure what I must released this and no one suggested doing it.
