Performance Optimizations
* Intel Architecture processors
* Improved performance of int8 compute functionality for future Intel Xeon Scalable processor (code name Sapphire Rapids). The functionality is disabled by default and should be enabled via [CPU dispatcher control](https://oneapi-src.github.io/oneDNN/dev_guide_cpu_dispatcher_control.html).
* Improved performance of compute functionality for future Intel Core processor with Intel AVX2 and Intel DL Boost instructions support (code name Alder Lake).
* Improved fp32 inner product forward propagation performance for processors with Intel AVX-512 support.
* Improved `dnnl_gemm` performance for cases with `n=1` on all supported processors.
* Intel Graphics products
* Introduced NHWC format support for activations for int8 primitives.
* AArch64-based processors
* Improved performance of fp32 and int8 convolution, and softmax primitives for processors with SVE 512 support.
* Improved performance of fp32 convolution via Arm Compute Library (ACL).
* Improved performance of convolution with a combination of `sum` and `relu` post-ops via ACL.
Functionality
* Extended [eltwise primitive](https://oneapi-src.github.io/oneDNN/dev_guide_eltwise.html) with support for `mish` and `hardswish` algorithms.
* Extended [binary primitive](https://oneapi-src.github.io/oneDNN/dev_guide_binary.html) with support for comparison operators.
* Introduced support for post-ops in GPU resampling implementation.
* Introduced asymmetric quantization support for int8 deconvolution.
* Introduced binary post-ops support for matmul primitive.
Usability
* Improved presentation of oneDNN primitives in VTune Amplifier.
* Introduced Linux perf support for AArch64.
* Introduced support for Fujitsu C++ compiler.
* Introduced a build time check for minimal supported ACL version. Currently oneDNN requires ACL 21.02 or later.
* Added support for cuDNN 8.x
