Oct 21, 2019, SuiteSparse 5.6.0
* GraphBLAS 3.1.1: OpenMP parallelism and MATLAB interface
Oct 20, 2019, SuiteSparse 5.5.0
* GraphBLAS 2.3.5: Collected Algorithm of the ACM
* UMFPACK 5.7.9: fix for compiling in MATLAB R2018b; BLAS library
* SPQR, CHOLMOD: fix to *_make.m for compiling in MATLAB; same version
* KLU: fix to Tcov/Makefile; no change to version number
* CXSparse 3.2.0: version was incorrect in CXSparse/Include/cs.h;
the corresponding CSparse v3.2.0 had the correct version information
in its cs.h include file.
* ssget and MATLAB_Tools/SuiteSparseCollection: update to sparse.tamu.edu
* Mongoose 2.0.4: update to sparse.tamu.edu
Dec 28, 2018: SuiteSparse 5.4.0
* GraphBLAS 2.2.2: many upgrades and new features, a few bug fixes
* CHOLMOD 3.0.13: fix to cholmod_core.h (for latest CUDA)
* SPQR 2.0.9: fix to SuiteSparseQR.hpp (for latest CUDA)
* UMFPACK 5.7.8: minor change to umf_analyze.h (not a bug, but the
parameter names in the *.h did not match the *.c.
* ssget: new matrices
* Mongoose 2.0.3: simpler cmake
* SuiteSparse_config: added JOBS option for parallel make, also added to
GraphBLAS, CHOLMOD, SPQR, UMFPACK, Mongoose, and metis-5.1.0
July 5, 2018: SuiteSparse 5.3.0
* GraphBLAS 2.0.3: bug fix to GxB_resize, better cmake script
* new package: Mongoose (version 2.0.2)
* fixed metis gk_arch.h for Windows
* UMFPACK 5.7.7: modified comments in umfpack*symbolic.h
* added contributor license for all of SuiteSparse
* updated and renamed MATLAB_Tools/UFcollection to SuiteSparseCollection
Mar 15, 2018: SuiteSparse 5.2.0
* GraphBLAS 2.0.1: bug fix to GxB_kron
* SuiteSparse_config: corrected back to SO_VERSION 5
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.
* CHOLMOD 3.1.12: bug fix (no change to the CHOLMOD ABI or API)
* KLU 1.3.9: minor edit, not a bug fix, but code is more clear now
Dec 28, 2017: SuiteSparse 5.1.2
* improved build process for GraphBLAS
* minor change to CSparse/Lib/Makefile, no change in CSparse version
Dec 17, 2017: SuiteSparse 5.1.1
* GraphBLAS added to top-level SuiteSparse/Makefile
* GraphBLAS 1.1.1: bug fix to *assign, split AxB for faster compile,
added memory usage statistics, AxB performance improvment
* minor update to [AMD CAMD KLU]/Doc/Makefile's, no change to
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)
Nov 25, 2017: SuiteSparse 5.0.0
* added GraphBLAS Version 1.0.0
* 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.
Aug 2015: SuiteSparse version 4.4.6
* SPQR: changed default tol when A has infs, from inf to realmax (~1e308)
July 2015: SuiteSparse version 4.4.5
* CHOLMOD 3.0.6:
- minor fix to CHOLMOD (disabling modules did not work as expected)
- added MATLAB interface for row add/delete (lurowmod)
* KLU 1.3.3: Fix for klu_dump.c (debugging case only)
* UFcollection: added additional stats for matrix collection
* AMD: changed the default license. See AMD/Doc/License.txt for details.
Mar 24, 2015: SuiteSparse version 4.4.4
* CHOLMOD version number corrected. In 4.4.3, the CHOLMOD_SUBSUB_VERSION
string was left at '4' (it should have been '5', for CHOLMOD 3.0.5).
This version of SuiteSparse corrects this glitch.
* Minor changes to comments in SuiteSparse_config.
* SPQR version 2.0.1 released (minor update to documentation)
Jan 19, 2015: SuiteSparse version 4.4.3
* CHOLMOD 3.0.5: minor bug fix to MatrixOps/cholmod_symmetry
Jan 7, 2015: SuiteSparse version 4.4.2
* CHOLMOD 3.0.4: serious bug fix in supernodal factorization,
introduced in CHOLMOD 3.0.0 (SuiteSparse 4.3.0). Can cause segfault,
and has no user workaround.
Oct 23, 2014: SuiteSparse version 4.4.1

minor update to CHOLMOD (non-ANSI C usage in one *.c file, affects
