Extension changes after game published

If a game using extensions is published on a site like liluo or any other, would it change if extensions are later changed? or the extension published with the game are not affected?

When added to a project, your project contains a unique copy of the extension, that you can also modify at will. As such, you can think of them as part of your events, they are compiled from your project files and stored on every build you make, like your normal events. You modifying the extension in your project, or an update being published for the extension will not affect your game.
