- 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)

- 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

- worked around a problem in the pre-AVX kernels 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 and N1
- 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
