Full Changelog: 2026.0.0...2026.1.0

oneAPI Data Analytics Library 2026.0.0

oneDAL is happy to introduce 2026.0.0 release!

🚩 Removals and ABI Compatibility

• The following functionality is removed in the 2026.0.0 release:
  • Deprecated input formats from oneDAL’s C++ interfaces
  • Matrix, PackedSymmetricMatrix and PackedTriangularMatrix data types
  • ODBC, KDB and MySQL data sources
  • The algorithms listed in the 20251015-DAAL-algorithms-deprecation RFC
  • The DAAL APIs listed in the 20251022-DAAL-interfaces-deprecation RFC, but their functionality is available through other APIs.

🚨 What's New

• Introduced new oneDAL functionality:
  • Switched the static-link oneDAL C++ library to use dynamic linkage to the DPC++ components of MKL instead of static-linking them
  • Moved the GPU and SPMD components of oneDAL into separate libraries that are now optional dependencies, substantially reducing the size of CPU-only installs

New Contributors

• @vyevtyus made their first contribution in #3357
