v0.15.0

Summary

The 0.15.0 represents a milestone in which dpctl.tensor.usm_ndarray object now implements all special Python operators, except __matmul__ and __rmatmul__.

The dpctl.tensor increases its array-API conformance test suite pass rate to 81.8%, (passed: 916, failed: 84, skipped: 119).

Details
