+Samples for CUDA Developers which demonstrates features in CUDA Toolkit. This version supports [CUDA Toolkit 12.5](https://developer.nvidia.com/cuda-downloads).
 
 ## Release Notes
 
 This section describes the release notes for the CUDA Samples on GitHub only.
 
-### CUDA 12.4
-
-- Hopper Confidential Computing Modes do not support Video samples, nor do they support host-pinned memory due to the restrictions created by CPU IOMMUs. The following Samples are affected:
-  - convolutionTexture
-  - cudaNvSci
-  - dct8x8
-  - lineOfSight
-  - simpleCubemapTexture
-  - simpleIPC
-  - simpleLayeredTexture
-  - simplePitchLinearTexture
-  - simpleStream
-  - simpleTexture
-  - simpleTextureDrv
-  - watershedSegmentationNPP
-
+### CUDA 12.5
 
 ### [older versions...](./CHANGELOG.md)
 
 ## Getting Started
 
 ### Prerequisites
 
-Download and install the [CUDA Toolkit 12.4](https://developer.nvidia.com/cuda-downloads) for your corresponding platform.
+Download and install the [CUDA Toolkit 12.5](https://developer.nvidia.com/cuda-downloads) for your corresponding platform.
 For system requirements and installation instructions of cuda toolkit, please refer to the [Linux Installation Guide](http://docs.nvidia.com/cuda/cuda-installation-guide-linux/), and the [Windows Installation Guide](http://docs.nvidia.com/cuda/cuda-installation-guide-microsoft-windows/index.html).
