# 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](https://pypi.org/project/holoscan) and [Holoscan CLI](https://pypi.org/project/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](https://github.com/nvidia-holoscan/holoscan-cli#deprecations) 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.
