Looking at current browser market shares on netmarketshare.com (first link that came up via google search) it looks like this version of chrome accounts for 0.07% of traffic this month. Why are you pinned on such an old version? Interestingly enough, the older version 45 has 6.08% share. Is some operating system pinning chrome 45 and perhaps providing security updates?
