Update or version bump?

Any chance we could get an update or version bump? The plug-in seems to work fine on 4.9.7 but I don’t know everything to look for, or if there’s newer ways of doing things in the code to make it better.

Anyway the plug-in page here complains that the plug-in is old and untested on my version of WordPress, an security plugins like wordfence warn that the plug-in hasn’t been updated constantly.

It would be very much appreciated if the author could have a look!
