Maintained or not?

Dear Chris,

as others, too, I am an enthusiastic user of your great extension.
You released the last version of it to years ago.
In the meantime WordPress claims, that your extension is not tested with the last 3 major releases of WordPress.
To be able to plan:
Please let your fans know, whether you plan to release a new version of your extension soon, or not.
Thank you very much in advance!
Kind regards,
Gerald
