Yep, that means you can no longer access your news and article feeds in one central web application. But if you’re afraid of losing all your subscriptions, don’t worry because there’s a way to save it all.
Simply head to Google Takeout, log in with your Google account, and select the “choose services” button, and select “Google Reader”, and click the “create archive button”. Wait for your archives to create and then simply download it. [Source]
