v1.2.0 (July 25, 2025)

July 25, 2025: version 1.2.0

* v2.1 C API: using the new GrB_get/set methods in the C API;
    LAGraph can now use a "vanilla" GraphBLAS that supports the v2.1
    C API.  If SuiteSparse:GraphBLAS is used, v9.0.0 is required.
* src/utility: random number generator
* src/utility/LAGraph_MMRead: now exploits 32-bit integers if using
    SuiteSparse:GraphBLAS v10.

Full Changelog: v1.1.1...v1.1.4

v1.1.1 (Jan 10, 2024)

Changes in this release (LAGraph v1.1.1):

updates to build system:

• find_package for OpenMP looks for C components only, and uses the GLOBAL keyword only for cmake 3.24 or later.
• libm linked in via cmake CheckSymbolExists
• workaround for a very old MacOS case (math.h includes some breaking extensions, powerpc only)

update to benchmarks: using the proper enum type in the triangle-count test.

This version also appears in SuiteSparse 7.5.0, alongside GraphBLAS 9.0.0: https://github.com/DrTimothyAldenDavis/SuiteSparse .

v1.1.0 (Dec 30, 2023)

Dec 30, 2023: version 1.1.0

* major change to build system: by Markus Mützel
* port: to 32-bit systems

This version also appears in SuiteSparse 7.4.0 ( https://github.com/DrTimothyAldenDavis/SuiteSparse/releases/tag/v7.4.0 ).

v1.0.2 (Aug 29, 2023)

Version 1.0.2: Aug 2, 2023

* port: removed GxB_SelectOp so LAGraph v1.0.2 can be compiled with
    SuiteSparse:GraphBLAS v8.x.
