+# Performance Optimizations
+## Intel Architecture Processors
+  * Improved fp16/bf16 softmax performance with relaxed [accumulation mode](https://oneapi-src.github.io/oneDNN/dev_guide_attributes_accumulation_mode.html#doxid-dev-guide-attributes-accumulation-mode).
+  * Added support and improved perfomance for fp8 matmul with bf16/fp16.
+
+## Intel Graphics Products
+  * Introduced initial optimizations for GPUs based on Xe3 architecture.
+  * Improved performance for convolution for Intel Arc Graphics for Intel Core Ultra processors (Series 2) (formerly Lunar Lake).
+
+## AArch64-based Processors
+
+# Functionality
+  * Introduced support for `select` algorithm in binary primitive. The functionality is optimized for Intel CPUs.
+  * Enabled support for matmul primitive with grouped quantization on weight along N dimension
+  * Introduced support for fp16/bf16 compressed weights in fp32 matmul on Intel CPUs.
+  * Introduced support for grouped scales and zero points in reorder primitive.
+  * Enabled support for 4d weight scale in matmul primitive.
+  * [experimental] Extended microkernel API:
+		Introduced int4 quantization support.
+		Fpmath mode API
+# Usability
+  * Relaxed memory object lifetime requirements created with CPU engine and SYCL runtime. New behavior is aligned with GPU engine.
+  * Improve verbose diagnostic to better identify issues during dispatching, primitive and kernel creation for CPU primitive and GPU (in case of OpenCL implementation) primitive implementations.
+  * Improve verbose diagnostic to simplify debugging of nGEN fallbacks.
+  * Enabled frame pointers support on Intel64 platforms to improve integration with profilers.
+# Validation
+  * Extended benchdnn with support and validation for fp8 matmul patterns for tensor tags in RNN primitive validation.
+# Deprecated Functionality
+
+# Breaking Changes
+  * Updated minimal supported CMake version to 3.13 (was 2.8.12).
+  * Updated minimal supported GCC version to 8.0 (was 4.8).
+  * Updated minimal supported Clang version to 11.0 (was 3.0).
