## Release Information

NVIDIA JetPack 7.2.1 with Jetson Linux 39.2.1. This section includes highlights of what&#39;s new, supported Jetson hardware platforms, and a complete list of included library and SDK versions.

### What&#39;s New

NOTE: For full details, refer to [Jetson Linux release notes](https://docs.nvidia.com/jetson/archives/r39.2.1/ReleaseNotes/Jetson_Linux_Release_Notes_r39.2.1.pdf).

Jetson Linux 39.2.1 is the latest Jetson Linux release that supports NVIDIA JetPack 7.2.1. The following are the highlights for this release:

1. 

Support for Jetson T3000 emulation

2. 

Agent skills for video pipelines

3. 

ISO now flashes the Jetson Orin Nano Developer Kit with Super Mode flashing configuration by default.

4. 

Support for PCN211461 and PCN211462.

5. 

Fixes for known issues and security vulnerabilities.

**BLOG POST** : Learn more about the key features in this release in the supporting blog post [here](https://developer.nvidia.com/blog/nvidia-jetpack-7-2-1-adds-agentic-video-skills-and-t3000-emulation/).

**NOTES** : 

- 

With JetPack 7 series, Jetson software aligns with the Server Base System Architecture (SBSA), positioning Jetson Thor alongside industry-standard ARM server design. SBSA standardizes critical hardware and firmware interfaces, delivering stronger OS support, simpler software portability, and smoother enterprise integration. Building on this foundation, Jetson Thor now supports a unified NVIDIA® CUDA® 13.0 installation across all Arm targets, streamlining development, reducing fragmentation, and ensuring consistency from server-class systems to Jetson Thor.

- 

The manual flashing instructions have slightly changed because of Thor using SBSA architecture. Please follow the [manual flashing instructions](https://docs.nvidia.com/jetson/archives/r39.2.1/DeveloperGuide/SD/FlashingSupport.html#) carefully.

- 

There is no more SD Card image for Jetson Orin Nano Developer Kit. Use the unified ISO image to flash the developer kit using a USB stick. Follow the instructions on [Getting Started Guide](https://docs.nvidia.com/jetson/agx-thor-devkit-4fed1671/user-guide/latest/quick_start.html).

- 

If you’re re-installing JetPack 7.2.1 using ISO on an already installed system, please carefully follow the instructions in the[Getting Started Guide](https://docs.nvidia.com/jetson/agx-thor-devkit-4fed1671/user-guide/latest/quick_start.html).

- 

The ISO image-based flashing now uses Super flashing configuration on Jetson Orin Nano Developer Kit by default.
