Apparently the one we've all been using was over a decade old. The USDA has just released an updated version. The map is pretty nicely done and easy to use.

According to this, I am 3a where I thought i was 3b. Lots of variation around my place going from 2a to 4b in just a handful of miles probably due to the extreme differences in elevation. None of the old maps I’ve seen had this level of detail.
What zone are you and did it change any?
