About image caching

Note: These rules only apply when retrieving the menu image. The "normal" week communicates via Websockets and is updated automatically when a new menu is available.

To avoid unnecessary requests, the module returns a cached version of the menu image if it has not been told to force an update (see docs for info on how to do that), or if the script has restarted. This is nothing to worry about. Here, the rules of when the menu is retrieved are documented:

• When a menu object has been initialized and you want to get data for the first time (for example when the script restarts)

• When the week number changes related to when the menu was last updated.
