Improvements
------------

We've added the following improvements for DLAMI support in this release of the AWS Neuron SDK:

* Support for PyTorch 2.8 (Amazon Linux 2023, Ubuntu 22.04) single-framework DLAMI
* Updates multi-framework DLAMI virtual environments to support PyTorch 2.8
* All Neuron packages and their dependencies have been upgraded to support version 2.26.0 of the AWS Neuron SDK

Behavioral changes
------------------
* End-of-support for the Transformers NeuronX library starts with the 2.26.0 release of the AWS Neuron SDK. As a result, the PyTorch inference Deep Learning Container (DLC) will no longer provide the ``transformers-neuronx`` virtual environment in both single and multi-framework DLAMIs. For more details, see :ref:`announce-eos-tnx`.
