### Bug fixes

* Add concept restriction to ensure `ConstMult` inline function only hit with arithmetic-values times complex values. Fixes build failures with the test suite when enabling OpenMP, and disabling BLAS and Python under clang.
[(#936)](https://github.com/PennyLaneAI/pennylane-lightning/pull/936)

* Bug fix for `applyMatrix` in `lightning.tensor`. Matrix operator data is not stored in the `cuGateCache` object to support `TensorProd` obs with multiple `Hermitian` obs.
[(#932)](https://github.com/PennyLaneAI/pennylane-lightning/pull/932)
