.. _neuron-2-33-1-whatsnew: .. meta:: :description: Release notes for AWS Neuron SDK release v2.33.1, a patch release with bug fixes for Neuron 2.33.0. :date-modified: 11/11/2026 AWS Neuron SDK Release Notes - v2.33.1 ======================================= **Release Date**: November 11, 2026 Release **2.33.1** of the AWS Neuron SDK includes bug fixes applied to the AWS Neuron SDK v2.33.0. See :doc:`the Neuron SDK v2.33.0 release notes ` for the full set of changes that shipped with the 2.33.0 release. Changes in 2.33.1 ----------------- Neuron Runtime ^^^^^^^^^^^^^^ * Corrects the internal execution order that triggers DMA engines in HWDGE (``DmaDirect2d`` and ``DmaTranspose`` on non-GPSIMD engines) to remove a race condition between HWDGE and other transpose DMA (like collectives) that can hang the TPB AXI fabric. * Adds a check that halts GPSIMD with an error message when it encounters ``DmaGatherTranspose`` indices whose validity is not strictly in groups of 16 (instead of causing an xbar AXI hang). Framework packages ^^^^^^^^^^^^^^^^^^ * ``libtorch_neuronx_lite``, ``libneuronxla``, and ``jax_neuronx`` are rebuilt against the updated Neuron Runtime and dependencies. They contain no functional changes. Package updates --------------- Neuron 2.33.1 updates the following packages. All other packages are the same as in Neuron 2.33.0. * ``aws-neuronx-collectives``: 2.35.49.0 * ``aws-neuronx-dkms``: 2.31.8.0 * ``aws-neuronx-oci-hook``: 2.19.74.0 * ``aws-neuronx-runtime-lib``: 2.35.33.0 * ``jax_neuronx``: 0.10.0.1.0.15472 * ``libneuronxla``: 3.0.12293.0 * ``libtorch_neuronx_lite``: 2.11.0.1.0.4089, 2.12.0.1.0.4089, and 2.13.0.1.0.4089 * ``nrtpy``: 2.35.33 ---- .. grid:: 1 :gutter: 2 .. grid-item-card:: :link: latest-neuron-release-artifacts :link-type: ref :class-card: sd-border-1 **Neuron 2.33.1 release artifacts** ^^^ The libraries and packages updated in this Neuron release.
