I don't like the idea of auto-updates either. Look what it caused to Liberty Unleashed - the client is now stuck several seconds when you launch it, because the auto-updater source is offline and client still attempts to find the downloads. When SA-MP is eventually discontinued at some point in future, the client could cause troubles for players too.

The auto-update is also not needed, as it was announced, there most likely won't be no further updates after 0.3.9.

I'm operating my server since 0.2.2 and there never were any significant issues for players to update their clients. If anything, I would just suggest server can display a dialog to player, if they connect with different version than the server is running on - this could be used to inform players where to download the latest client. The hostname might be too short to put all the relevant info to. But this is just minor suggestion and is probably not needed either.
