what dlc?

when i go online its just the same as it was two days ago, havent had a prompt to download a dlc, as i go through the endless loading screens of gta v there is some nice pics of this dlc but when i get in game...nothing. very strange indeed

There isn't any changes that are apparent right when you log in

Look at the new cars added and new super expensive gold plane and helicopter. I think there is also a new gun in the shop.
