Update Status

Hi, author of this plugin,
Congratulations on your excellent plugin. I have been very pleased with your plugin over a number of years. I am not aware of any flaws in the operation of the current version of your plugin. However, I have the following concerns. There have been no updates in about a year and a half. Your page on WordPress lists WordPress version 4.8.8 (which is several versions back), as the last compatible version. That page also states “Warning: This plugin has not been tested with your current version of WordPress.” You have not responded to anyone’s posts on your forum in that same year and a half. I wonder if you might address the subject of the current status of your plugin and your future plans for this plugin.
Thank you very much.
