There seem to be some reports that the implementation of new hand baggage rules are going to be delayed by the EU for six months until November:

I'd take them with a pinch of salt for the moment, simply because I have not found an official press release from the European Commission and the story does not appear to be widely covered.

I guess we'll know closer to 6 May, when I think the rules were due to come into effect.
