Because Google now requires and API key with a valid billing address and payment method many users wanted a free mapping solution. This necessitated switching to a multiple mapping service provider library that I can use to switch mapping providers.
Since Google Maps is no longer natively being used, its controls such as zoom and layer type (road, satellite) do not exist. The controls on the maps being presented by this library and not Google.
All that said, yes, the satellite layer control had existed before the last update. More control over the map provider and layer controls will come in further updates.
Hope this helps!
