Sept 1, 2025: version 1.2.1

    * MaxFlow: performance bug fix for results in HPEC'25 paper.

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.
    * added many experimental algorithms and utilities
    * cmake and github CI: many minor improvements

Feb 20, 2025: version 1.1.5

    * minor updates to github CI
    * typos: in helloworld demos

Aug 20, 2024: version 1.1.4

    * fix MMWrite when matrix is dense

Mar 22, 2024: version 1.1.3

    * minor updates to build system

Jan 20, 2024: version 1.1.2

    * minor update to build system

Jan 10, 2024: version 1.1.1

    * minor update to build system

Dec 30, 2023: version 1.1.0

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

Version 1.0.2: Aug 2, 2023

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

Version 1.0.1: Dec 26, 2022

    * bug fix: LAGraph_MMWrite incorrectly created a Matrix Market
        file with "array pattern" format, which is invalid.
    * header updates: with copyright info
    * CONTRIBUTING.md: renamed the file
    * CODE_OF_CONDUCT.md: added, from https://www.contributor-covenant.org
    * FindGraphBLAS.cmake and FindLAGraph.cmake: revised to find both dynamic
        and static libraries, and to find the version number from the include
        file if it's not present in the filename of the library.
    * LAGraph_FastGraphletTransform: now able to compile it when OpenMP
        is not available.
    * bug fix: LAGRAPH_VANILLA option fixed.  Added "make vanilla" to the
        Makefile.  GxB_*_TypeName methods are required, even for a "vanilla"
        GraphBLAS.

Version 1.0.0: Sept 20, 2022

    * LAGraph v1.0 released.

Jan 29, 2019
