+**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.
