How specifically has the breakfast improved over the years?

I remember before always being served on my North Atlantic KL Y flights:

a hot breakfast dish such as an omelette or pancakes,
unlimited bread and
hot croissants with butter and jam,
cheese and/or ham,
fresh juice,
coffee, tea,
fresh fruit or fruit salad,
yoghurt.

And beer and wine or bloody mary's if you asked for them.

--- What have they done to improve on this?
