Included issuses

Issue	Area	Description	Required Update	Sensor OS
DFND-13560	Sensor installation	When installing or upgrading a sensor on Linux machines, the installation log had unexpected results, including numerous repeated and redundant lines in the log. This was due to the results of a verification of the presence of prerequisite libraries on the machine. We have resolved this issue and the log entries have been streamlined for better use.	Sensor and server	Linux
DFND-14202	Sensor performance	Frequently, the sensor was not able to connect to the Dynamic Sensor Connections service to get sensor content updates. This occurred when the token was expired and a new token was not downloaded. This issue has been resolved and the sensor is now able to continually connect to the Dynamic Sensor Connections service as expected on a continuous basis.	Sensor and server	Windows
