I have this latest stable BI release, have installed it and have the BI settings location tab fields populated with my geographical data and the OpenWeatherMap API key.
The weather updates successfully every 15 minutes.
The BI user manual states that a number of macros should then be available but there are none to select on the BI settings macro tab.

What am I missing?
