+ expanded hardware and data-type support, a correctness fix, and an
+ enumeration update:
- - Support for the BF16 data type (and BF16 input with FP32 output)
- on gfx90a (MI200/MI210/MI250). Users running mixed-precision workloads
- on Aldebaran hardware could not use BF16 with hipBLASLt in ROCm 7.1.
- - hipBLASLtExt operation APIs are now supported on gfx11XX and gfx12XX
- (RDNA3 and RDNA4 GPUs), extending the reach of the extension API to
- consumer and workstation hardware.
- - Sigmoid Activation Function is added as a new epilogue option, with a
- follow-up enumeration value fix (ROCm 7.2.1) ensuring the activation
- variant is correctly identified by downstream code.
- - Added HIPBLASLT_OVERRIDE_COMPUTE_TYPE_XF32 environment variable,
- allowing users to override the XF32 compute type when precision
- trade-offs are desired.
- - Fixed: users could encounter HIPBLAS_STATUS_INTERNAL_ERROR with various
- matrix sizes in CPX (complex) mode. This caused silent failures in
- complex-valued GEMM operations.

[ Where problems could occur ]
- * The BF16 and hipBLASLtExt API additions are new code paths that
- were not exercised in 7.1.x. A regression in these paths would manifest
- as HIPBLAS_STATUS_INTERNAL_ERROR or incorrect numerical results in
- BF16/mixed-precision GEMM on gfx90a, or as API call failures on
- gfx11XX/gfx12XX hardware using the Ext API.

- * The Sigmoid epilogue addition introduces new kernel dispatch logic.
- A regression would appear as incorrect activations or a segfault when
- HIPBLASLT_EPILOGUE_SIGMOID_EXT is requested.

- * The CPX mode fix changes the code path for complex GEMM operations.
- Although the old behaviour was a bug, any application that worked around
- the HIPBLAS_STATUS_INTERNAL_ERROR by adjusting matrix sizes may behave
- differently with the fixed path. Symptom: unexpected success (benign) or
- a different error at a different size boundary.

- * The Tensile device library (GPU kernels) is rebuilt for each upstream
- release. A regression in kernel selection heuristics could cause
- performance degradation or incorrect results for GEMM shapes that
- exercise newly added or modified kernel variants.

[ Other Info ]
- * ABI: public API is fully stable. abipkgdiff (7.1.1 vs 7.2.4) reports
- 0 removed, 0 changed, 0 added public functions/variables. Internal
- symbol churn (origami:: heuristics, __hip_cuid_* build IDs) is expected
- and not ABI-relevant. SONAME: libhipblaslt.so.1.1 (unchanged).
- No debian/libhipblaslt1.symbols file exists — tracking this as a
- follow-up item.
