Disclaimer, Ford is rolling it out step-wise so it may or may not yet be available to you.

Installation went smoothly (thankfully different to when I installed v4.4) and it only took 10-15 minutes. Had to re-pair my phone and everything seems to be working. At least temporarily it seems to have corrected the problem where when I asked for a particular tract on my iPod, sync would repeat the correct tract but play something completely different. Repeating the request would then select another incorrect song, in spite of sync correctly repeating the song I asked for. I'll withhold a conclusion about this fix for now because re-installing v4.4 would also correct this for a couple of days before it went back to the problem. This was my biggest gripe that came along with v4.4.

Here's the official Ford blurb on the update from the website:
