In my experience, BMW's website is often behind on changes like this and, specifically, changes to the 1 Series configurator seem to come dead last. During last year's MY switchover, the 1 Series configurator was the last to be updated and it didn't happen until 5-6 weeks into the MY (dealers were already selling 2013s off the lot). Lame.
Here's an odd thing I noted: according to the updated 1 Series order guide, Blue Water Metallic goes EOP this month, but it was already removed from the configurator a while back. Similarly, it appears that the Light Burl Walnut interior trim goes EOP this month (according to the guide), but it's still on the configurator. And as you noted, the ZED package and the Mineral White paint options are nowhere to be found even though they supposedly start production soon.
It might be a while -- I say talk to your dealer.
