 OpenBLAS ChangeLog
+====================================================================
+Version 0.3.30
+19-Jun-2025
+
+general:
+ - fixed an installation problem with the thread safety test in gmake builds
+ - fixed spurious overwriting of an input array in complex GEMMT/GEMMTR
+ - fixed naming of GEMMTR in error messages from XERBLA
+ - fixed compilation of SBGEMMT/SBGEMMTR in CMake builds
+ - fixed the implementation of ?NRM2 to handle INCX=0 correctly
+ - removed tests for CSROT and ZDROT that relied on unspecified behavior
+ - fixed a performance regression in multithreaded GEMM that was particularly
+   serious on POWER targets
+ - fixed linking issues when using LLVM's flang-new with gmake
+ - fixed a potential thread safety problem with C11 atomic operations
+ - further improved the workload partitioning in parallel GEMM
+ - fixed omission of LAPACKE interfaces for CGESVDQ,CTRSYL3 and ?GEQPF in 
+   CMake builds
+ - fixed mishandling of setting NO_LAPACK to FALSE, and incorrect dependencies
+   for LAPACK function SPMV in CMake builds
+ - added explicit CMake options for building LAPACKE and shared libraries
+ - simplified and improved handling of OpenMP options in CMake builds
+ - reworked Windows DLL generation in CMake builds to ensure correct symbol
+   renaming (pre/postfixing) and optional generation of PDB files for debugging
+ - updated the Perl script version of the gensymbol utility for use with 
+   Windows-on-Arm
+ - Fixed building with (Mingw) gmake on Windows to ensure completeness of the
+   LAPACK included in the static library (potential race condition due to the
+   Windows version of the "ln" utility creating snapshot copies rather than links)
+ - fixed unwanted deletion of the lapacke_mangling.h file by "make clean"
+ - fixed potential duplication of a _64 suffix on library names in CMake builds
+ - fixed compilation of the C fallback copies of the LAPACK code with GCC 15
+ - included fixed from the Reference-LAPACK project:
+   - fixed a truncated error message in the EIG part of the testsuite
+     (Reference-LAPACK PR 1119)
+   - fixed too strict check in LAPACKE_?gesdd_work (PR #1126)
+   - fixed memory corruption when calling ?GEEV with non-finite data (PR #1128)
+   - fixed missing initialization of a variable in C/GEQP3RK (PR #1131)
+   - fixed 2nd dimension chosen in C/ZUNMLQ transposition operation (PR #1135)
+
+x86_64:
+ - fixed an error in the SBGEMV kernel for Cooper Lake/Sapphire Rapids
+ - fixed corner cases of NAN and INF input handling in CSCAL and ZSCAL
+ - improved the compiler identification code for flang-new
+ - fixed a potential build issue in the ZSUM kernel
+ - fixed "argument list too long" errors when building on MacOS
+ - added cpu autodetection support for several new Arrow Lake models
+ - fixed conditional inclusion of the fast path SGEMM kernel in DYNAMIC_ARCH
+ - fixed compilation with the MinGW build of GCC 15
+
+arm64:
+ - fixed cpu type detection of A64FX and some ThunderX models (broken in 0.3.29)
+ - added support for the AmpereOne/1A cpus in DYNAMIC_ ARCH builds
+ - added an optimized SBGEMM kernel for NEOVERSEV1
+ - improved 1xN SBGEMM performance by forwarding to SBGEMV 
+ - introduced a stepwise increase of the thread count used for
+   SGEMM and SGEMV on NEOVERSEV1/V2 in relation to problem size
+ - introduced a stepwise increase of the thread count used for
+   DGEMV on NEOVERSEV1 in relation to problem size
+ - introduced a stepwise increase of the thread count used for
