Poor wording.  E.g. merchants need to do something, unless they sell stuff by hand: turn off their automated bitcoin processing.

What about miners against public pools? I'm assuming we should check the pool website for status, but is there anything specific we can do?

@JedDaniels, yes, you could also check bitcointalk to find a pool operator that is clearly running the correct version.
