Versioning

This describes the versioning scheme used for the Azure SDK and firmware.

Azure Kinect SDK Versioning

Azure Kinect uses Semantic Versioning.

  • Increasing the major version indicates a breaking change has been made and a loss of functionality may result. The client application may require updates to use the new version.
  • Increasing the minor version indicates new features have been added in a backward compatible way.
  • Increasing the patch version (sometimes called iteration version) implies changes have been made to the binary in a backward compatible way.

More details about release versioning can be found here

Firmware Versioning

The Azure Kinect firmware is composed of 4 different firmware versions. These firmware versions are exposed through k4a_hardware_version_t. Here is a sample of that hardware version:

RGB Sensor Version:  1.6.98
Depth Sensor Version:1.6.70
Mic Array Version:   1.6.14
Sensor Config:       5006.27

This version can also be simplified as 1.6.098070014 where 098, 070, and 014 are the patch versions of each component version, converted to a zero-based 3 digit form, and concatenated.
