Create new tag release

Hi,
A lot has happened since v3.3.1. Please consider adding a newer tag.
Reasons explained in #402.
Thanks.

Hi,
Is there any news on this ?
I just migrated from arch to nixos and one of the big part of my setup is the mailsync script which is out of date in the nixpkgs as mutt-wizard is still using the version 3.3.1 https://github.com/NixOS/nixpkgs/blob/master/pkgs/by-name/mu/mutt-wizard/package.nix.
Creating a new release would make it very simple to update the pkg.
Thanks a lot.
