- bug fix sensor stuck in bootloader (ds230/ds240) by upgrading bootloader. Some sensors were affected, stuck every 10th to 20th (hot) reboot. 
- bug fix multipage auth reception

20240130-1326
- bug fix creation of zombie processes (harmless)
- bug fix start process, initialization of wlan interfaces was incomplete resulting in starting the application twice (start, crash, start) instead of once
- added support for Docker builds/licenses

20240108-1539
- add debug output for the MQTT connection in /tmp/mqtt.log 
- add dummy CPU load to increase the temperature in cold environments. This should benefit the reliability  if the outside temperature is -20 degree Celsius

20231012-1105
- add watchdog function to check if the wlan adapters are still in monitor mode
- improved reboot function; sometimes reboot was not executed and the sensor did not reboot

20231006-1600
- bug fix, resetting wlan interfaces to monitor mode in case the dronescout process was terminated
- bug fix, when rebooting, shutdown wireless interfaces
- added a hook/script /root/custom.sh. Here, custom code (outside firmware) can be implemented

20230920-1626
- bug fix 100% cpu load in transmit_mode = 2
- support for ds240 receiver

20230828-1643
- remove esptool reset ble device
- add support for new ds230 rx board (instead of seperate wlan/ble adapters)

20230605-1350
- removed --insecure flag from update script to make sure only firmware is downloaded from the official download.bluemark.io server
- improved algorithm to surpress WLAN transponder signals on neighbouring channels in case the RSSI is very strong: only surpress adjacnet channel detections if the payload is similar.
- added description about the potential risks of using transmit mode 1. It is recommended to switch to mode 2.

20230329-1042
- add transmit mode 2: combine all Remote ID payloads into one MQTT message at publish it at a user-defined interval.

20230104-1650
- implement an algorithm to surpress WLAN transponder signals on neighbouring channels in case the RSSI is very strong. (If for instance a tranponder is detected on channel 6 at -45 dBm, it will also be detected at channel 4, 5 7 and 8. The algorithm will suppress those detections on adjacent channels.)

20221213-2153
- bug fix, version 20221208-1250 did have some internal code parts enabled by mistake.

20221208-1250
- added two options transmit_mode and aggregate_data in dronescout.conf. See manual.
- don't output debug/verbose information during firmware upgrade
- improved reboot function. In case the PoE power supply is at a critical level (e.g. bad cable, old PoE switch), shutdown first interfaces to prevent a hanging sensor.

20211210-1627
- first public release
