TomaIsTosik What version do you see in the lower-left corner of the Main Menu? The current version is 1.113.297. If you have that, there's nothing to update.
If you see an earlier version, repair the game and look again.
The newest items, released a few days ago, are part of a Sims Delivery Update. You can check for updates under Options > Game Options > Sims Delivery. It make take a few minutes for the content to install, and you'll need to restart the game to see it.
If that doesn't help, please open Documents > Electronic Arts > The Sims 4 and delete the content folder. Load the game, and if the SDX download doesn't start on its own, check again under Sims Delivery. Either way, give it a few minutes to download, then quit and reload to see whether the content appears.
Keep in mind that the items don't necessarily show as new, so you may have to search for them manually.
