Will the Linux client notify me when a new binary is available to download? I love the convenience of auto-updating launchers like GoG Galaxy, but I would prefer to play on Linux, and I would like to get any relevant patches as soon as they are released.

What is the Linux client of which you speak? Gog doesn't support Linux in that way. Are you talking about the blue dot on the web site, indicating updates? That doesn't work most of the time. Are you talking about lgogdownloader? I suppose you can set up a cron job to look for updates with it.

I see. Well, I don't let any game touch the 'net, so I can't help there. I've just never heard of the game executable being called a client, except for multi-player on-line games.

I wouldn't be a big fan of the game going to the internet myself due to privacy concerns. But maybe try using lgogdownloader, it will help you download updates in an automated way. I haven't tried the newer galaxy options but it should even be able to handle the installation with them.
