 # Release Notes
 
+## New in Release 2.15.0
+
+Post-training Quantization:
+
+- Breaking changes:
+  - ...
+- General:
+  - ...
+- Features:
+  - (TorchFX, Experimental) Preview support for the new `quantize_pt2e` API has been introduced, enabling quantization of `torch.fx.GraphModule` models with the `OpenVINOQuantizer` and the `X86InductorQuantizer` quantizers. `quantize_pt2e` API utilizes `MinMax` algorithm statistic collectors, as well as `SmoothQuant`, `BiasCorrection` and `FastBiasCorrection` Post-Training Quantization algorithms.
+  - (TensorFlow) The `nncf.quantize()` method is now the recommended way for the quantization initialization for Quantization-Aware Training. Please refer to an [example](examples/quantization_aware_training/tensorflow/mobilenet_v2) for more details about how to use new approach.
+- Fixes:
+  - ...
+- Improvements:
+  - Significantly faster data-free weight compression for OpenVINO models: INT4 compression is now up to 10x faster, while INT8 compression is up to 3x faster. The larger the model the higher the time reduction.
+  - AWQ weight compression is now up to 2x faster, improving overall runtime efficiency.
+  - Peak memory usage during INT4 data-free weight compression in the OpenVINO backend is reduced up to 50% for certain models.
+- Deprecations/Removals:
+  - (TensorFlow) The `nncf.tensorflow.create_compressed_model()` method is now marked as deprecated. Please use the `nncf.quantize()` method for the quantization initialization.
