Test for recent WordPress release?

Hi, love your plugin, but is there any chance you could do some testing and release an update for a more recent version of WP, a 5.x release? I don’t suppose anything will actually be broken, but the uncertainty is a bit worrying and some tools are flagging it as ‘abandoned’. The WP Plugins directory warns “This plugin hasn’t been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.”

All the best, David
