thank you!

Hi @monchi. Might you know when this fix will be shipped?

[yukukotani]

@sonahovhannisyan
Hi, I'm afraid I don't know because i'm not a maintainer but just one of the contributors.
Maybe @shashachu or @Tapchicoma knows something about that.

[sonahovhannisyan]

Ah ok, thanks @monchi. Let's wait to hear from them then.

I suppose it will happen this week.
