Microsoft claims that the latest build 10162 would bring along with it improved stability, a better battery life (which everyone appreciates, I am sure), performance and compatibility to previous releases. Considering how this particular version happens to be just a few builds newer as opposed to the previous release and that we are staring down the final furlong of the RTM build, there should not be any expectations, or rather too high expectations when it comes to new features.
Folks who happen to be in the Slow ring will need to wait, since Microsoft are still mulling over whether this release is for you, assuming no huge roadblocks are run into after Fast ring users have had their fair share of fun with it. [Press Release]
