What happened to 5.5.1.2 client?

[Zoltan Forray/AC/VCU]

Anyone know what happened to the 5.5.1.2 patch for the Windows client?

I downloaded it last week but the "readme" for what was new with this
update would never list anything beying 5.5.1.1

Now when I went back to check again, 5.5.1.2 is MIA?
