 ## hipBLASLt 1.0.0 for ROCm 7.0.0
 
+### Added
+
+* Added the ``HIPBLASLT_MATMUL_DESC_A_SCALE_MODE`` and ``HIPBLASLT_MATMUL_DESC_B_SCALE_MODE`` attributes for configuring scalar (``HIPBLASLT_MATMUL_MATRIX_SCALE_SCALAR_32F``), vector (``HIPBLASLT_MATMUL_MATRIX_SCALE_OUTER_VEC_32F``) or block (``HIPBLASLT_MATMUL_MATRIX_SCALE_VEC32_UE8M0``) settings.
+
 ### Changed
 
-* ``HIPBLASLT_MATMUL_DESC_A_SCALE_POINTER_VEC_EXT`` and ``HIPBLASLT_MATMUL_DESC_B_SCALE_POINTER_VEC_EXT`` are deprecated, use ``ROCBLASLT_MATMUL_DESC_A_SCALE_MODE`` and ``ROCBLASLT_MATMUL_DESC_B_SCALE_MODE`` attributes to set scalar (``HIPBLASLT_MATMUL_MATRIX_SCALE_SCALAR_32F``) or vector (``HIPBLASLT_MATMUL_MATRIX_SCALE_OUTER_VEC_32F``).
 * The non-V2 APIs (``GemmPreference``, ``GemmProblemType``, ``GemmEpilogue``, ``GemmTuning``, ``GemmInputs``) in the Cpp header are now the same as the V2 APIs (``GemmPreferenceV2``, ``GemmProblemTypeV2``, ``GemmEpilogueV2``, ``GemmTuningV2``, ``GemmInputsV2``). The original non-V2 APIs are removed.
