  • fixed a CMAKE-specific build problems on older versions of MacOS
  • worked around linking problems on old versions of MacOS
  • corrected installation location of the lapacke_mangling header in CMAKE builds
  • added type declarations for complex variables to the MSVC-specific parts of the LAPACK header
  • significantly sped up ?GESV for small problem sizes by introducing a lower bound for multithreading
  • imported additions and corrections from the Reference-LAPACK project:
    • added new LAPACK functions for truncated QR with pivoting (Reference-LAPACK PRs 891&941)
    • handle miscalculation of minimum work array size in corner cases (Reference-LAPACK PR 942)
    • fixed use of uninitialized variables in ?GEDMD and improved inline documentation (PR 959)
    • fixed use of uninitialized variables (and consequential failures) in ?BBCSD (PR 967)
    • added tests for the recently introduced Dynamic Mode Decomposition functions (PR 736)
    • fixed several memory leaks in the LAPACK testsuite (PR 953)
    • fixed counting of testsuite results by the Python script (PR 954)

x86-64:

  • fixed computation of CASUM on SkylakeX and newer targets in the special
    case that AVX512 is not supported by the compiler or operating environment
  • fixed potential undefined behaviour in the CASUM/ZASUM kernels for AVX512 targets
  • worked around a problem in the pre-AVX kernel for GEMV
  • sped up the thread management code on MS Windows

arm64:

  • fixed building of the LAPACK testsuite with Xcode 15 on Apple M1 and newer
  • sped up the thread management code on MS Windows
  • sped up SGEMM and DGEMM on Neoverse V1
  • sped up ?DOT on SVE-capable targets
  • reduced the number of targets in DYNAMIC_ARCH builds by eliminating functionally equivalent ones
  • included support for Apple M1 and newer targets in DYNAMIC_ARCH builds

power:

  • improved the SGEMM kernel for POWER10
  • fixed compilation with (very) old versions of gcc
  • fixed detection of old 32bit PPC targets in CMAKE-based builds
  • added autodetection of the POWERPC 7400 subtype

your installation location, if you plan to have OpenBLAS findable via pkgconfig or cmake on your Windows system)
