[Plugin: Ultimate Taxonomy Manager] Future development

Hello,
Thanks for this excellent plugin.

Before settling on one particular custom taxonomy manager, I want to make sure the one I pick is going to continue to be developed. I’d hate to do a WP core update in the future only to find the taxonomy/custom-post-type plugin I am using breaks.

Would you please share what your plans are with this plugin? Is it still under active development?
