+# Version 3.3.0 (October 2025)
+
+## What's new in 3.3.0
+
+This version of the App SDK is compatible with [Holoscan SDK](https://pypi.org/project/holoscan) CUDA 12 version, [holoscan-cu12](https://pypi.org/project/holoscan-cu12).
+
+It has also been tested compatible with the latest [MONAI at v1.5.1](https://pypi.org/project/monai/1.5.1/) which supports the latest PyTorch v2.8. PyTorch version 2.7 and above have embedded CUDA 12 Runtime `>= 12.6.77`, which is required by Holoscan v3.6 and v3.7 CUDA12 version on X86_64 Linux workstations.
+
+### Key changes
+
+- Compatible with the latest MONAI v1.5.1 and Holoscan v3.7 CUDA12 version, [holoscan-cu12](https://pypi.org/project/holoscan-cu12).
+- Volumentric image converted from DICOM has consistent `affine` and `space` metadata, e.g. converted image in original DICOM orientation is in `LPS`.
