Main changes:
- Improving Join procedure : 
  * Adding possibility to configure DevNonce feature (only applicable for OTAA devices) from dashboard and GMS API: activation/de-activation.
  * Taking into account the technical recommendations for preventing state synchronization issues around LoRaWAN™ 1.0.x join procedure.
- Improving MIC error management: 
  * Differenciating counter issues and MIC error. Providing more information about MIC errors: "Reused FCntUp", "Exceed FCntUpMAxGap", "Invalid MIC".
- Improving Software Update :
  * Adding the possibility to upload and delete software update to the server repository. Selecting a software available in the server repository and using it through workflow and GMS API.
- Improving Backhaul configuration:
  * Adding the possibility to configure Ethernet static IP (DHCP deactivated), with optionally first and second DNS.
  * Adding the possibility to configure cellular backhaul: APN (1 for Wirnet Station and up to 10 for Wirnet iBTS, iFemtoCell, and iStation), login, password, MCC, MNC.
- KPI Management:
  * Adding the option to stop end-devices KPIs computing.
- Improve end-devices and gateways export and import:
  * Export a list of end-devices or gateways to CSV format, with fields (all or only authorized ones) sorted by category.
  * Import a previous export of end-devices or gateways.
- Adding a cluster overview:
  * Panel with all the cluster information: name, customer, payload type, push enabled, push configuration, geolocation, geolocation expiration date.
  * Histogram bar with the actual status of all the cluster's end-devices.
- Better support of AS923 region countries:
  * Specific regional parameters defined for Japan, Indonesia, and Vietnam.
- Provide payload encoding:
  * Add new field “encodingType” (Base 64 or Hexadecimal)in DataUpDto and PushDataUpDto.
  * On the dashboard, display encoding type used for payload (dataUp, dataDown, mcDataDown, messages).
- Radio channels configuration : 
  * sharing gateway channel configuration between BSC and LNS: The end-device's CFlist is created from the gateway radio channel configuration.
  * Improve mac commands: send / receive mac commands.
  * Multiple gateways with possible different channel configurations.
- Support of additional Wirnet stations: 
  * Support of Wirnet iStation (with Embedded 3.2.x Software release).
  * Support of Wirnet iFemtoCell-evolution (with Embedded 3.3.x Software release).
- Management of 16-channels configuration:
  * By default, only 8 channels are configured after CFList within the Join Accept.
  * For regions with dynamic channels plans, the end-devices are now informed of the additional 8 channels by NewChannelReq dedicated MAC command(s)
- Timestamping for buffering feature :
  * In case of network latency or backhaul disconnection, the message is delayed so the reception timestamps from gateway and WMC can be different.
  * Separation between message receive timestamps from gateway and WMC.
  * Parameter gwRecvTimeadded to figure out the gateway reception timestamp.
  * Both timestamp values (gwRecvTime and recvTime) are displayed on dashboard and pushed to the end user in DataUpDto
- When immediate sending, RX window choice is no more based on the networkMaxDelays, current ping value is now used.
- Add possibility to filter on power-loss alarm.
- Improvement of downlink messages process:
  * For classA & classC, downlinks are now sent to the gateways immediately after being provisioned by LNS in order to increase the chance to target the RX1 window.
- Improvement of RX1DROfsset management:
  * RX1DROffset=0 (no offset applied on DR) is now used for JOIN Accept.
  * RX1DROffset=n (if set) is only applied on subsequent downlinks.

Main restrictions:
Some residual cases of downlinks stucked in Class C.
