The routing feature is still a long way off. Most likely not even the next release but the subsequent one.
While the routing aspect is not that bad, there is a lot of stuff under the hood to do for recording virtual ports.
I've gotten most of synth recording working at this point which is cool. There is a lot of dev work and testing so be patient. It will get there.
That work has been going on in parallel with other development. This month a lot of time was spent on the Windows 10 stuff and bug fixes of course. Most likely you will see the start screen for the next update which is going to be an awesome feature.
