“Simple Responsive Slider” appears to be abandoned.

Since a week I get a notification from WordFence about Simple Responsive Slider
“The Plugin “Simple Responsive Slider” appears to be abandoned.”

We really want to keep using the plugin.

The plugin isn’t updated in 2 or more years. Is the plugin still good? Can we keep using it? Of is it better to go look for another similar plugin?

Thanks in advance!
