There have been some more venue changes wih regard to the applicant file. It's all explained here:

Basketball was moved to Las Ventas bullring because it appears Real Madrid may not be building their new arena in the Campo de las Naciones cluster, so to avoid problems, the bid team reached an agreement with the city council to roof Las Ventas and host the basketball tournament there. I don't know if the roof would be temporary or permanent, it depends on what the city council decides, but from what I'm reading, I think it's likely to be permanent.
Hockey and volleyball will not be held in the Olympic Park anymore in order to use already existing venues and not to build new infrastructure. Hockey will now be held in the Campo de las Naciones cluster, right next to rugby and archery, and volleyball will be moved to the Palacio de Deportes, in the city center. The temporary venue for beach volleyball will be built in the Olympic Park instead of in the Casa de Campo cluster.
As the Palacio de Deportes is hosting volleyball now, judo and taekwondo will be moved to the IFEMA exhibition center in the Campo de las Naciones cluster, which will also host badminton, fencing, weightlifing, wrestling and table tennis. Boxing was also planned to be held here, but it's now been moved to the Palacio de Vistalegre, close to the Casa de Campo cluster.
So in the end, the only permanent venues that would need to be built if Madrid is awarded the Olympics are the gymnastics arena in the Olympic Park, the Madrid/Getafe Regatta Centre for canoe sprint, rowing and open water swimming in Getafe, the La Gavia Slalom Centre for canoe slalom in southern Madrid, halfway between the Olympic Park and the Magic Box, and the Paracuellos Shooting Center in Paracuellos del Jarama, close to the Barajas airport. The velodrome and the beach volleyball stadium would now be the only temporary venues.
