This is a patch release on top of v1.28.0, containing support for device-free WebGPU compilation, improved compatibility with sandboxed Windows processes, and targeted graph-validation fixes.

WebGPU EP

  • Added support for device-free compile-only sessions, enabling offline graph transformation and optimized-model serialization without access to GPU hardware (#29681)

Bug Fixes

  • Prevented an access violation in Windows processes under Win32k lockdown by skipping DXGI device discovery (#29755)
  • Allowed zero-input EPContext nodes, aligning their schema with support for compiling zero-input models (#29799)
  • Hardened FastGelu fusion to skip malformed Mul and Pow patterns (#32016)
  • Added validation for in-memory external initializer references, rejecting unregistered or mismatched data before graph transformation (#32042)
