Jan 1, 2025January 2025 (oneapi-src/oneDNN) focused on stabilizing the build, clarifying ownership, and increasing portability, while continuing to push performance-enabled features. Key outcomes include build-system hardening, metadata/format hygiene, governance cleanup, and significant relocation of third-party dependencies to simplify maintenance and CI. XE/JIT/OCL enhancements progressed, including compute scales, FP8, typed scales, and quantization offsets, with improvements targeting cross-arch performance. Version bumped to 3.8.0 to signal a stable, customer-facing release. Testing and bug fixes were applied to reduce CI noise and improve reliability across CPU and OpenCL paths, including test permissions, dst-scale handling, and bias shape corrections on the OpenCL path. These changes reduce CI friction, increase portability across compilers/architectures, and establish clearer ownership for ongoing maintenance.
