Dec 30, 2023: version 7.4.0
* major change to build system: by Markus Mützel. Includes a
top-level CMakeLists.txt that builds all packages, and support for
pkg-config. Default location of files is now listed below, where
PACKAGE is one of the packages in SuiteSparse:
* CMAKE_INSTALL_PREFIX/include/suitesparse: include files
* CMAKE_INSTALL_PREFIX/lib: compiled libraries
* CMAKE_INSTALL_PREFIX/lib/cmake/SuiteSparse: helper *.cmake scripts
for all of SuiteSparse
* CMAKE_INSTALL_PREFIX/lib/cmake/PACKAGE: *Config.cmake scripts for a
specific package
* CMAKE_INSTALL_PREFIX/lib/pkgconfig/PACKAGE.pc: *.pc pkg-config
files with information for a specific package
Additional changes are listed below.
* LAGraph 1.1.0: new package: graph algorithms based on GraphBLAS
* ParU 0.1.0: new package: parallel unsymmetric multifrontal method,
with Mohsen Aznaveh. This is a stable package but is tagged as 0.1.0
since the API is still subject to change.
* CHOLMOD 5.1.0: full support for sparse single precision matrices,
bug fixes in the GPU Module.
* AMD 3.3.0: minor change for CHOLMOD 5.1.0 tests
* CAMD 3.3.0: minor change for CHOLMOD 5.1.0 tests
* SuiteSparse_config 7.4.0: added wrappers for single-precision BLAS/LAPACK,
added SUITESPARSE_TIME macro.
* *_version: added methods to all package that didn't have them:
AMD, CAMD, COLAMD, CCOLAMD, BTF, CSparse, CXSparse, KLU, BTF, RBio,
SPEX, SPQR, and UMFPACK.
Oct 31, 2023: version 7.3.1
* CHOLMOD 5.0.1: remove "I" from cholmod.h.
Oct 23, 2023: version 7.3.0
* CHOLMOD 5.0.0: initial support for sparse single precision matries.
CHOLMOD:Core replaced with CHOLMOD:Utility
* updated to require CHOLMOD 5.0.0:
Example 1.4.3, GPUQREngine 3.3.3, KLU 2.2.2, SPQR 4.2.2, UMFPACK 6.2.2
* SuiteSparseLAPACK.cmake: allow the use of BLIS/FLAME for LAPACK;
update from Theirry Thomas.
* build system: further updates to cmake, by Markus Muetzel.
Oct 18, 2023: version 7.2.2
* CHOLMOD 4.2.2: bug fix to CHOLMOD/Supernodal (heuristic to determine
# threads to use for last supernode was incorrect)
Oct 7, 2023: version 7.2.1
* GraphBLAS 8.2.1: bug fix to GrB_mxm; incorrect handling of typecasting
* cross-compiler support: replace check_c_source_runs with _compiles,
for GraphBLAS and SuiteSparse_config, and remove check for
getenv("HOME").
* cmake update: add "None" build type, from Antonio Rojas, for Arch Linux,
to all *Config.cmake files for all packages except CSparse (CXSparse
is built instead, and CSparse does not have CSparseConfig.cmake file)
* UMFPACK v6.2.1 and GPUQREngine v3.2.1: copies internal include files
from other SuiteSparse packages (AMD and SuiteSparse_GPURuntime),
so these two packages can be built independently.
Sept 8, 2023: version 7.2.0
* build system: modern cmake structure, by Markus Muetzel.
Most packages updated to vX.2.0 where X is unchanged (except SPQR
and Example package).

Jan 17, 2023: version 7.0.0
* SuiteSparse_config: now v7.0.0
* SuiteSparse_config struct: removed from external visibility to simplify
the Windows build, so that no global data is externally visible.
This requires a major version number increase from v6.x to v7.x for the
SuiteSparse meta-package (which has the same version number as
SuiteSparse_config). Added get/set methods to SuiteSparse_config to
access the contents of the struct.
* NFORTRAN: option added to ignore any Fortran methods, even if a Fortran
compiler is available.
* port of new cmake-based build system to Windows
* UMFPACK 6.1.0: copy/serialize/deserialize methods: added new methods to
copy, serialize, and deserialize the Numeric and Symbolic objects. By
Will Kimmerer, revised by T. Davis.
Dec 29, 2022: SuiteSparse 6.0.4
* NFORTRAN: option added to disable Fortran entirely
* GraphBLAS v7.4.1: global free pool disabled, and GrB_mxm heuristics

* GPUQREngine 2.0.2: minor change to build system
* GraphBLAS 7.3.3: -latomic added if needed, using ANSI C11 atomic functions
for gcc (atomic_compare_exachange_weak instead of __atomic_* variants),
chunk factor revised for GrB_mxm (generic saxpy3 method);
minor change to build system
* KLU 2.0.2: Fortran no longer required; minor change to build system
* LDL 3.0.2: minor change to build system
* Mongoose 3.0.2: fixed matrix download in python test scripts (no change
to the compiled library itself, other than the version/date);
minor change to build system
* RBio 3.0.2: minor change to build system
* SPEX 2.0.2: minor change to build system
* SPQR 3.0.2: Fortran no longer required; minor change to build system

no Fortran compiler found; minor change to build system
* UMFPACK 6.0.2: Fortran no longer required; minor change to build system
* Example: simple package that illustrates how to use SuiteSparse
Find*.cmake modules in cmake.
* not changed from SuiteSparse v6.0.1: ssget, CSparse, MATLAB_Tools
Nov 12, 2022: SuiteSparse 6.0.1
* BLAS: C prototypes for the Fortan BLAS were unintentionally exposed to
the user application. Removed. If you want to use them, see the
instructions in SuiteSparse_config.h.
Nov 12, 2022: SuiteSparse 6.0.0
* major update: using CMake build system for all packages
* CMake Find*: all packages now have a Find*.cmake. See
SuiteSparse_config/cmake_modules.
* integers: int (32-bit) and SuiteSparse_long (nominally 64-bit) replaced
with int32_t and int64_t. The SuiteSparse_long #define has been
deprecated and removed. Replace its use with int64_t in any code that
uses SuiteSparse v6.0.0 or later. This is unlikely to change any
use of any SuiteSparse package, but since it's possible that
SuiteSparse_long was 32-bits on some platforms, the SO_VERSIION of
all packages has been increased by one.
* UMFPACK: new options to support ParU. Single umfpack.h include file.
* CHOLMOD: Single cholmod.h include file.
* SuiteSparse/metis-5.1.0: now embedded into CHOLMOD, in a different
name space. No longer an independent library.
* SPDX License Identifier: added to each file. No change in license.
* BLAS/LAPACK interface: now supports any Fortran BLAS/LAPACK, with
either 32-bit (default) or 64-bit integers, via FindBLAS.cmake.
* SPEX: replaces SLIP_LU
Aug 25, 2022, SuiteSparse 5.13.0
* GraphBLAS v7.2.0: see GraphBLAS/Doc/ChangeLog for details.
* performance: more compact serialization (ZSTD added, now the
default compression method).
* MATLAB interface: faster linear indexing, reshape, bandwidth,
istril, istriu, isbanded, isdiag. C(I,J)=A can now grow the
size of C.
* features: reshape methods, cube root operator, isStoredElement
* bugs: a minor bug; user-defined types were incorrectly limited to
128 bytes in size in v7.0.3.
Apr 10, 2022, SuiteSparse 5.12.0
* GraphBLAS v7.0.3: see GraphBLAS/Doc/ChangeLog for details.
* performance: GrB_mxm, GrB_assign, and transpose
* bug fix: vector iterator for bitmap
* revised ACM TOMS submission: Doc/toms_parallel_grb2.pdf
* spec bug: GrB_Matrix_diag was implemented incorrectly,
thus requiring a version v7.x
Mar 14, 2022, SuiteSparse 5.11.0
* GraphBLAS v6.2.5: see GraphBLAS/Doc/ChangeLog for changes.
Primary ones highlighted here:
* v2.0 API: v6.x complies with the v2.0 C API of the GraphBLAS Spec.
Note that GrB_wait, GrB_Info are now different than in the v1.3
C API Specification (and in v5.x of SuiteSparse:GraphBLAS).
* GxB_Iterator: to iterate over rows/cols/entries of a matrix or vector
* GxB_eWiseUnion: like eWiseAdd but with the op always applied
* GxB_Matrix/Vector_sort: to sort the vectors of a matrix
* better performance: for sparse-times-dense and dense-times-sparse,
in particular; also other cases for GrB_mxm, up to 10x faster.
* Apple Silicon: port @GrB to Octave 7 (thanks to Gabor Szarnyas)
* added cpu_features: by Google
* added LZ4/LZ4HC: compression library, http://www.lz4.org (BSD 2),
v1.9.3, Copyright (c) 2011-2016, Yann Collet, All Rights Reserved.
* iso-valued matrices and vectors: to exploit the common case of
an unweighted graph
* bug fixes: 4 bugs fixed since SuiteSparse 5.10.1 with
GraphBLAS v5.0.5. 12 other bugs appeared in the interim but
appeared in versions after v5.0.5 but fixed before ever
affecting SuiteSparse itself.

Mar 12, 2018:
* GraphBLAS 2.0.0: with changes to API to conform to the latest
specification. The SO_VERSION of GraphBLAS must change,
as a result, since this affects both the ABI and API interface.

version numbers of AMD, CAMD, or KLU
Dec 1, 2017: SuiteSparse 5.1.0
* GraphBLAS 1.1.0
* minor update to SPQR Makefile (version remains unchanged;
no change to source)

* replaced UFget with ssget
Oct 3, 2017: SuiteSparse 4.5.6
* changed COLAMD, CAMD, and CCOLAMD to BSD 3-clause,
to match AMD. No other changes; version numbers of
packages unchanged.
Apr 17, 2017: SuiteSparse 4.5.5
* minor fix to SuiteSparse/Makefile for 'make install'
Dec 8, 2016: SuiteSparse 4.5.4
* minor update to SPQR for ACM TOMS submission
May 4, 2016: SuiteSparse 4.5.3
* minor changes to Makefiles
Apr 1, 2016: SuiteSparse 4.5.2
* licensing simplified (no other change); refer to PACKAGE/Doc/License.txt
for the license for each package.
Feb 1, 2016: SuiteSparse 4.5.1
* update to Makefiles. Version 4.5.0 is broken on the Mac.
That version also compiles *.so libraries on Linux with
underlinked dependencies to other libraries in SuiteSparse.
For example, AMD requires SuiteSparse_config. The links to
required libraries are now explicitly included in each library,
in SuiteSparse 4.5.1.
* minor change to CHOLMOD/Check/cholmod_write.c, when compiling with
options that disable specific modules
Jan 30, 2016: SuiteSparse 4.5.0
* better Makefiles for creating and installing shared libraries
* CHOLMOD now uses METIS 5.1.0, which is distributed with SuiteSparse
* fix for MATLAB R2015b, which changed how it creates empty matrices,
as compared to prior versions of MATLAB. This change in MATLAB
breaks many of the mexFunctions in prior versions of SuiteSparse.
If you use MATLAB R2015b, you must upgrade to SuiteSparse 4.5.0
or later.
Jan 1, 2016: SuiteSparse 4.4.7
* note that this minor update fails on the Mac, so its
listed on my web page as a 'beta' release.
* Improved the Makefiles of all packages. They now create *.so
shared libraries (*.dylib on the Mac). Also, there is now
only a single SuiteSparse_config.mk file. It now determines
your system automatically, and whether or not you have METIS
and CUDA. It also automatically detects if you have the Intel
compiler or not, and uses it if it finds it. There should be
no need to edit this file for most cases, but you may need to
for your particular system. With this release, there are almost
no changes to the source code, except for the VERSION numbers
defined in the various include *.h files for each package.
