Curiouser and curiouser... We'll just have to wait until our copy turns up.
It does seem a bit odd though, as there is usually lots of paperwork floating around when phraseology changes but just a little bit (I'm thinking of "FL wun hundred" and "Tree hundred, three zero zero" which were very widely publicized).
What you've described seems quite a big change by comparison.
Waiting with interest, BEX
