The changes to the Olympic masterplan have been agreed by all involved with the bid-winning designs and will, according to the official line, result in no cost increases or delays.
The most significant changes:
there is to be a closer alliance between the landscaping and the existing topography of the whole Olympic Park area;
the broadcast and media centre is moving from the Stratford City plot to a site at Hackney Wick in the north-west corner of the park;
to accommodate the move of the media centre, the volleyball courts are moved off the site to Earl's Court in wast London;
the temporary basketball courts are moved to a site north-west of the stadium;
the fencing facilities are reduced to one hall rather than two and moved to a temporary site near Stratford City;
the hockey pitches are moved to a site nearer the Olympic Village; and - the cycling velodrome moves south of the A12 to make space for a new Paralympic tennis centre.
