A Breakdown of changes for the 1.5 Driver & SDK releases

Release Notes

2026-01-27 - Kindly Kraken 1.5.0-beta.6 (Public Beta)

Highlights of this Release

This release adds many new features and improvements such as (non-conformant) support for the OXR API, which enables WebXR support in Chromium-based browsers on Windows, automatic gameboard incline detection, Direct3D 12 support, and wide-angle camera image streaming support.

Source-Level Incompatibility

The reference frame called GBD, which was used in various struct field names to refer to the reference frame associated with the physical gameboard, has been replaced with a reference frame called STAGE. With the introduction of automatic gameboard orientation detection, we wanted to draw a distinction between the reference frame of the physical gameboard, which may now have arbitrary orientation, and that of the display region, which will always remain gravitationally aligned (i.e. Z pointing up). The pose of the physical gameboard is made available via a new query, and is now referred to as the BOARD reference frame.

Known Issues

  • Attempting to stream camera images to an application built with a prior SDK while running the 1.5.0-beta.6 driver will result in no images being sent. This will be fixed for the final 1.5.0 driver. Until then, if camera images are needed, please use the 1.4.2 driver.
