Development team hardly works on the free product until there is any major vulnerability or security issue with the product.
The best way is to drop an email to bitdefender support at bitsy@bitdefender.com regarding your feedback and ask them to share it with the development team. In order to get a response back from the development team on your query you will have to stay in touch with the support team on the same email ticket.

Yes, it's still version 1.0.21.234
That is totally up to development team. More focus is on commercial/ paid version rather than free version.
