 - Add support for multi-node PTQ and export with FSDP2 in ``examples/llm_ptq/multinode_ptq.py``. See `examples/llm_ptq/README.md <https://github.com/NVIDIA/TensorRT-Model-Optimizer/tree/main/examples/llm_ptq#multi-node-post-training-quantization-with-fsdp2>`_ for more details.
 - Add support for Nemotron Nano VL v1 & v2 models in FP8/NVFP4 PTQ workflow.
 - Add flags ``nodes_to_include`` and ``op_types_to_include`` in AutoCast to force-include nodes in low precision, even if they would otherwise be excluded by other rules.
+- Enabled native Modelopt quantization support for FP8 and NVFP4 formats in SGLang. See `SGLang quantization documentation <https://github.com/sgl-project/sglang/blob/main/docs/advanced_features/quantization.md#using-nvidia-modelopt>`_ for more details.
+- Added modelopt quantized checkpoints in vLLM/SGLang CI/CD pipelines (PRs are under review).
