Shortcode button compatibility with TinyMCE 4.0

Hi,

I have recently upgraded to WordPress 3.9. However, since the upgrade I noticed the shortcode button in the TinyMCE is not working anymore. I suspect this has to do with the TinyMCE api update by WordPress, so it won’t correspond anymore with the plugin.

Is there by any chance a fix for this or can we expect an updated version of the plugin with a fix in it?

Thank you in advance!
