v10.3.0-beta1 (Dec 3, 2025)

Dec 3, 2025, version 10.3.0

* GrB_extract: performance improvement for C=A(I,J) when A is very large
    and (typically) hypersparse, and I is an explicit list and also large.
* GrB_(Matrix,Vector,Scalar)_dup:  pending work is now left unfinished;
    any pending work in the input matrix will appear in the copy.  In
    v10.2.0 and earlier, all pending work in the input matrix was finished
    first.  To obtain the behavior in v10.2.0 and earlier, simply call
    GrB_*_wait on the input matrix before calling GrB_*_dup.

What's Changed

• GraphBLAS 10.3.0: performance improvements by @DrTimothyAldenDavis in #437

Full Changelog: v10.2.0...v10.3.0-beta1

v10.2.0 (Nov 1, 2025)

Nov 1, 2025, version 10.2.0

* printing of user-defined types: get/set with GxB_PRINT_FUNCTION
* doc: documentation of GrB_Matrix_import/export was backwards
* performance: new GrB_assign kernel for C<C,struct> += A added

Full Changelog: v10.1.1...v10.2.0

v10.1.1 (July 25, 2025)

July 25, 2025: version 10.1.1

* gcc can now be used on the Power or s390:  workaround added;
    see Source/mxm/factory/GB_AxB_saxpy3_symbolic_fine_template.c.
    This resolves the issue found in v10.1.0.
* OpenMP usage: replace omp critical with lock/unlock.
* MATLAB: added method for getting/setting the JIT cache path.
* JIT file lock/unlock: removed; if multiple user processes use
    GraphBLAS at the same time, each must set their own unique JIT cache.
* (65) bug fix: theta type definitions for user-defined index binary ops
    were incorrectly typedef'd in the JIT kernels.

New Contributors

• @luszczek made their first contribution in #433

Full Changelog: v10.1.0...v10.1.1

v10.1.0 (June 1, 2025)

June 1, 2025: version 10.1.0

* add support for RISC-V vectorization: contributed by Rodion Suvorov
* added GRAPHBLAS_VANILLA: compile-time flag that disables all GxB methods
* gcc and the Power or s390 processor:  using gcc on the Power or s390
    architecture leads to a failure in the OpenMP atomic capture intrinsic.
    See Source/mxm/factory/GB_AxB_saxpy3_symbolic_template.c.  The cmake
    build system has been revised so that it refuses to use gcc on a
    Power-based or s390-based system.  Use clang or the IBM xlc compiler
    instead.
* GxB_STDC_VERSION: this is normally equal to __STDC_VERSION__ and is
    determined automatically in GraphBLAS.h.  If it is >= 2011012L,
    then C11 is being used and the polymorphic functions (based on
    _Generic) are available.  It can now be #define'd by the user
    application prior to its '#include "GraphBLAS.h"' statement.
    If a C++ compiler is used to compile the user application then
    GxB_STDC_VERSION is set to 199001L to denote C90 (and no _Generic
    keyword is used).  See GraphBLAS/Demo/Include/graphblas_demo.h
    for an example usage.
* minor updates to build system
* iterator methods: revised so they do not conflict with the copy of
    GraphBLAS v7.4.4 used inside MATLAB R2024b.  No effect on normal
    C API, so no change in major SO number for this release.
