The one in misc/makerelease/makerelease.go is particularly bad and probably warrants rotating our keys. I didn't update old weekly notes, and reverted some changes involving test code for now, since we're late in the Go 1.5 freeze. Otherwise, the rest are all auto-generated changes, and all manually reviewed.
