One recent thing I've noticed is a that a number of UK NOTAMS involving airfields, as published on the AIS website now only give an ICAO code and not the common name.
This slows down the flight planning process. If one doesn't recognise the ICAO one then has to go elsewhere to check which airfield it refers to.
Jolly irritating - some of us don't get much time to read and inwardly digest the NOTAMS (reams of 'em recently, especially since every man and his dog now seems to have a kite or a bird of prey, or a fireworks display, or all three).
