I configured a RPi B+ using the latest NOOBS found here: https://www.raspberrypi.org/downloads/noobs/, which I assumed had the latest Raspbian on it (Stretch, as of November 2017).

But after installing Raspbian and then performing `cat /etc/os-release` from an ssh session (logged in as the `pi` user) I'm seeing:

    PRETTY_NAME="Raspbian GNU/Linux 8 (jessie)"
    NAME="Raspbian GNU/Linux"
    VERSION_ID="8"
    VERSION="8 (jessie)"
    ID=raspbian
    ID_LIKE=debian
    HOME_URL="http://www.raspbian.org/"
    SUPPORT_URL="http://www.raspbian.org/RaspbianForums"
    BUG_REPORT_URL="http://www.raspbian.org/RaspbianBugs"

Which leads me to assume that it's Jessie, not Stretch that is installed. What is up with that? Either I'm reading the version information incorrectly or the latest NOOBS is installing Jessie not Stretch, or I'm losing my mind.

Which one is it?
