 This incompatibility is needed so connecting software is able to
 differentiate between HM-CFG-LAN and HM-CFG-USB.
 
+**Important security information:**
+Versions before 0.101 do not correctly transmit the AES channel-mask
+to the HM-CFG-USB, which results in signature-requests not being generated
+by the device in most cases. This can lead to processing of unsigned messages
+by the host-software. If you are relying on authenticated messages
+(with e.g. aesCommReq in Fhem) from devices like door-sensors and remotes,
+you should upgrade to at least version 0.101.

 ### Updating the HM-CFG-USB firmware to version 0.967: ###
 
 1.  Compile the hmcfgusb utilities like in the hmland HowTo above
     (steps 1 to 5) and stay in the directory

     `wget https://git.zerfleddert.de/hmcfgusb/firmware/hmusbif.03c7.enc`
 3.  Make sure that hmland is not running
 4.  Flash the update to the USB-stick:
     `./flash-hmcfgusb hmusbif.03c7.enc` (You might need to use `sudo` for this)
