When will whonix-gw templates offer the version of Tor with congestion control?

Tor is a very important release as it enables support for congestion control which:

Congestion control will eliminate the speed limit of current Tor, as well as reduce latency by minimizing queue lengths at relays. It will result in significant performance improvements in Tor, as well as increased utilization of our network capacity. In order for users to experience these benefits, we need Exit relay operators to upgrade as soon as possible.

Users of Tor versions 0.4.7 and above will experience faster performance when using Exits or Onion Services that have upgraded to 0.4.7.
