+* Tue Sep 30 2025 xu_ping <707078654@qq.com> - 15.0.3-1
+- Update to 15.0.3:
+  * fix for declaration of xSYCON and xHECON functions in LAPACK
+  * fix for rare corner-case in reshape()
+  * expanded the field class with .reshape() and .resize() member functions
+  * fix for fft() and ifft() when using FFTW3 in multi-threaded contexts
+  * added support for SuperLU 7.0
+  * added balance() to transform matrices so that column and row norms are 
+    roughly the same
+  * added omit_nan() and omit_nonfinite() to extract elements while omitting 
+    NaN and non-finite values
+  * added find_nonnan() for finding indices of non-NaN elements
+  * added standalone replace() function
+  * C++14 is now the minimum required C++ standard
+  * added preliminary support for matrices with half-precision fp16 element type
+  * added second form of cond() to allow detection of failures
+  * added repcube()
+  * added .freeze() and .unfreeze() member functions to wall_clock
+  * extended conv() and conv2() to accept the "valid" shape argument
+  * optionally use OpenMP parallelisation for fp16 matrix multiplication
+  * fix superfluous deprecation warning in hist()
+  * fix potential loss of precision when saving single-precision matrices as CSV files
