What content was added to gta online after launch?

The excerpt from Wikipedia offers a basic overview of Grand Theft Auto Online, noting its release dates across various platforms and its open‑world setting within the fictional state of San Ari­as. It describes the game’s core mechanics and its relationship to Grand Theft Auto V, but it does not mention any post‑launch updates, expansions, or additional content that Rockstar North released after the game’s initial launch. Therefore, based solely on the supplied evidence, there is no information available about content added to GTA Online after launch.
