plugin not updated for more than 5 months

Hi.

First of all, let me point out that this plugin is great and was able to resolve an issue I've had with another plugin, and I am very pleased to use it.

I just wanted to ask why this plugin hasn't been updated for more than 5 months now.

It's not officially supported by the latest version of WP, and as time goes by, it is potentially more and more vulnerable for security issues and so on.

Thanks.
