If you don't know what app_config.xml is, or if you don't use it for PrimeGrid's LLR apps, you can ignore this notice. This doesn't affect you.

But if you are using app_config.xml on any of our LLR apps, we are changing the plan class of the LLR app versions, and therefore your app_config.xml won't work after the changes. For details, as well as what you should do right now, please see this message. Comments, questions, and discussion are also located in that thread.
