**New features:**

* CPU runtime:

* Enabled weights decompression support for Large Language models (LLMs). The implementation
supports avx2 and avx512 HW targets for Intel® Core™ processors and gives up to 2x improvement
in the latency mode (FP32 VS FP32+INT8 weights comparison). For 4th Generation Intel® Xeon®
Scalable Processors (formerly Sapphire Rapids) this INT8 decompression feature gives 10-25%
performance improvement, compared to pure BF16 inference.
* Reduced memory consumption of compile model stage by moving constant folding of Transpose
nodes to the CPU Runtime side.
* Set FP16 inference precision by default for non-convolution networks on ARM. Convolution
network will be executed in FP32.

* GPU runtime: Added paddings for dynamic convolutions to improve performance for models like
Stable-Diffusion v2.1.

* Python API:

* Added the ``torchvision.transforms`` object to OpenVINO preprocessing.
* Moved all python tools related to OpenVINO into a single namespace,
improving user experience with better API readability.

* TensorFlow FE:

* Added support for the TensorFlow 1 Checkpoint format. All native TensorFlow formats are now enabled.
* Added support for 8 new operations:

* MaxPoolWithArgmax
* UnravelIndex
* AdjustContrastv2
* InvertPermutation
* CheckNumerics
* DivNoNan
* EnsureShape
* ShapeN

* PyTorch FE:

* Added support for 6 new operations. To know how to enjoy PyTorch models conversion follow

* Frameworks:

- PyTorch Updates: OpenVINO now supportsoriginally quantized PyTorch models, including models produced with the Neural Network Compression Framework (NNCF).
- PyTorch Updates: OpenVINO now supports originally quantized PyTorch models, including models produced with the Neural Network Compression Framework (NNCF).
- TensorFlow FE: Now supports Switch/Merge operations, bringing TensorFlow 1.x control flow support closer to full compatibility and enabling more models.
- Python API: Python Conversion API is now the primary conversion path, making it easier for Python developers to work with OpenVINO.
