No, the release named "10.3" in the NIMBUS article will not spontaneously
convert to 10.2.3 -- 10.2.2 is the end of the 10.2 line (at least until after the
new version is released).
I realize it's frustrating to wait on a critical fix, but there may be reasons why
it could not be fixed in the 10.2.x code base, and there isn't any way to push
the train out of the station while it's still taking on fuel, water, baggage, and
passengers.
