Well, I got today the time and I've just release version 2.0.14 with the following changes:

• Fix group creation
  Thanks for the report on this. It seems solved now.
  
• Separate record functionality from 'Send' button so it is more difficult to start recording an audio message by mistake
  
  Now, the Send button is only the Send button. There's a new button for recording audio that disappears when writing some text so the typing space is not reduced. I hope this solves the glitch that sometimes made us start a new recording unknowingly.

I hope you all enjoy this small changes It's already available at extras-devel and in a few hours will be available at extras-testing.
