Version 4.0.0 ( June 2026)#

What’s new in 4.0.0#

  • CUDA 13 is now used by default so CUDA version dependent packages have been updated accordingly.

  • Holoscan SDK and Holoscan CLI, the key dependencies if this SDK, are now pinned below version 4.3.0. This is because of the following reasons

    • Holoscan SDK version 4.2 provides all core functionalities to support this SDK.

    • MAP packaging support is deprecated starting from Holoscan CLI version 4.3.0.

  • More robust decoding of compressed images with nvImageCodec due to the use of improved GPU-accelerated libraries in the CUDA 13 toolkit.
