5.1 is in the final stages of beta testing. It took a bit longer than we expected, but it also includes some neat, unannounced features. We expect it out around the end of the month.
As mentioned, it does support flying a VOR and localizer, as well as adding full GPS steering support from compatible panel mounted GPS units. Tracking a VOR without needing a GPS, DG, or other external equipment like the competition does is a bit tricky!
