With Beta 1.1 more and more people wanted to share their hours playing GTA United with others, so the voices desiring an multiplayer got louder. SA:MP in Vice City / Liberty CitySince the modification requires more ressources than the original game it was delivered together with an tool called Limit Adjuster, which is based on a DirectX hook. Since the most important multiplayer modifications for San Andreas – Multi Theft Auto and San Andreas Multiplayer – are based on DirectX hooks, too, it was impossible to play the modification online. With version 1.2 a new Limit Adjustment system has been announced, which works different from the hook and allows the player to play simple multiplayer modifications. In 2008 the San Andreas: Multiplayer development team released a special client model for GTA United, which sets it's limits internaly new and allows the player to play online, too. Due the seperate limit adjustment system the United SA-MP client is compatible to all major release versions of the modification, including the upcoming version 1.2. However the GTA United Development team is not related into the development of this client and so it is just released as a seperate download.

So I'm assuming that either the SA-MP or the old U-MP client are still compatible with the new GTA United? But it might be an outdated text as well, so I'm not sure. Also, the changelog mentions a "# New Limit Adjuster" (second from bottom).
