The cfclient uses the protocol version reported by the firmware to decide which features to enable. Currently, each feature guards itself individually with a version check, but there is no central place that warns the user when their firmware is out of date.
A potential fix for the cflib2-based cfclient, could be to warn the user when they connect to the client with a firmware protocol version that is below what the client was built for, telling them that some features will not work. However, some features like the bootloader should always work.
