Difference between L4T R32.4.3 and L4T R32.4.2


We are currently using L4T R32.4.2 and Jetpack 4.4 on NX. In the release notes of L4T R32.4.3, we did not find any content for the difference between L4T R32.4.3 and L4T R32.4.2. Can you please tell us what are the main difference between those two L4T versions?

Some related questions we have: Is the Jetpack 4.4 with L4T R32.4.2 only a develop preview version? And is it recommended to switch to L4T R32.4.3 for production launch?


Hi hencl4o,

JetPack 4.4 GA is the latest production release, supporting all Jetson modules.

The key differences between R32.4.3 and R32.4.2 are issues fixed listed at release notes, and support for Jetson Xavier NX, also the new production versions of CUDA, TensorRT and cuDNN.
