July 14, 2020, SuiteSparse 5.8.1 * SLIP_LU v1.0.2: resolved issue #51 * GraphBLAS v3.3.3: bug fix (GraphBLAS issue #13) July 2, 2020, SuiteSparse 5.8.0 * SLIP_LU v1.0.1 added: for solving Ax=b exactly. Requires the GNU GMP and MPRF libraries. * GraphBLAS v3.3.1: see the GraphBLAS/Doc/Changlog * replaced UFget with ssget: affects nearly all packages: UMFPACK, KLU, CHOLMOD, CXSparse/CSparse, etc, but their version numbers are left unchanged since it affects the MATLAB tests only, not the compiled libraries. * ssget v2.2.0: better URL redirects * updates to SuiteSparse build system Apr 8, 2020, SuiteSparse 5.7.2 * GraphBLAS v3.2.2: port to Microsoft Windows (with MS Visual Studio) Feb 20, 2020, SuiteSparse 5.7.1 * SuiteSparse_config: update version number * Makefile: fixed install issue with README.txt Feb 20, 2020, SuiteSparse 5.7.0 * GraphBLAS 3.2.0: better performance, new ANY and PAIR operators, structural mask, GrB_DESC_* from 1.3 C API Specification. * CHOLMOD 3.0.14: minor update to cholmod_check to print a matrix * added: CONTRIBUTIING.md, CODE_OF_CONDUCT.md, README.md. 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.
