Compatibility with WordPress 4.0? Issue since update

Hi

I was loving your free plugin – but since I deactivated plugins to update to the new wordpress, I now get the “Plugin could not be activated because it triggered a fatal error.” message when I try to activate the plugin.

It worked fine until then.

I see 2 days ago there was an update – but it still shows support only to 3.9 somehing..

Will the plugin be made compatible ?

Thanks
