0.23.0

Features:

• The management of the downlink device-queue has moved to LoRa Server.
  Based on the device-class (A or C and in the future B), LoRa Server will
  decide how to schedule the downlink transmission.
• LoRa Server sends nACK on Class-C confirmed downlink timeout
  (can be set in the device-profile) to the application-server.

Changes:

Working towards a consistent and stable API, the following API changes have
been made:

Application-server API

• HandleDataDownACK renamed to HandleDownlinkACK
• HandleDataUp renamed to HandleUplinkData
• HandleProprietaryUp renamed to HandleProprietaryUplink
• GetDataDown has been removed (as LoRa Server is now responsible for the
  downlink queue)

Network-server API

• Added

  • CreateDeviceQueueItem
  • FlushDeviceQueueForDevEUI
  • GetDeviceQueueItemsForDevEUI

• Removed

  • SendDownlinkData

Note: these changes require LoRa App Server 0.15.0 or higher.
