The only thing that makes sense to me would be the change of the $DISPLAY to include an identifier that says which server it belongs to... maybe ssh previously ignored something of the format:
/tmp/launch-ATqbAa/:0
versus the current:
/tmp/launch-ATqbAa/org.macosforge.xquartz:0
or maybe it was getting a false-hit in its search of the xauth data before...
I dunno... either way, it's something easily ignored. I'm curious about why it might've suddenly appeared with the new $DISPLAY format, but since it is a benign warning, and I have tons of other things to worry about, I won't be giving it much additional though.
