2019-11-20 Berwin A Turlach <Berwin.Turlach@gmail.com> * DESCRIPTION (Version): New version is 1.5-8 * DESCRIPTION (Author): Added Cleve Moler as requested per CRAN policy * src/solve.QP.compact.f, solve.QP.f: Implemented fixes suggested at: https://chasethedevil.github.io/post/quadprog-nans/ https://github.com/cran/quadprog/pull/1/files 2019-05-05 Berwin A Turlach <Berwin.Turlach@gmail.com> * DESCRIPTION (Version): New version is 1.5-7 * src/Makevars, src/Makevars.win: Changed compiler flags so that the package should work with older versions of R (<3.6.0) again. 2013-04-17 Berwin A Turlach <Berwin.Turlach@gmail.com> * DESCRIPTION (Version): New version is 1.5-5 * src/util.f: Changed declaration of arrays in subroutine to avoid faults if R is running with array bound checks. 2011-05-12 Berwin A Turlach <Berwin.Turlach@gmail.com> * DESCRIPTION (Version): New version is 1.5-4. * R/quadprog.R, DESCRIPTION, src/aind.f, src/solve.QP.compact.f: src/init.c, src/quadprog.h, src/solve.QP.f: Updated e-mail details. 2010-04-09 Berwin A Turlach <berwin@maths.uwa.edu.au> * DESCRIPTION (Version): New version is 1.5-3. * tests/: added further test problems. * src/aind.f: changed argument ok from LOGICAL to INTEGER as per documentation on how logicals should be passed to FORTRAN code. * NAMESPACE: added .registration and .fixes argument to useDynLib directive. * R/quadprog.R: removed PACKAGE argument from FF calls and used registered symbols in namespace instead. 2010-04-08 Berwin A Turlach <berwin@maths.uwa.edu.au> * DESCRIPTION (Version): New version is 1.5-2. * src/init.c, src/quadprog.h, src/quadprog-win.def, src/Makevars: Implemented changes to register native routines and control visibility. At least one other package seems to call the FORTRAN code directly and checks of that package fail more gracefully if the interface to a registered FORTRAN routine changes. 2010-04-06 Berwin A Turlach <berwin@maths.uwa.edu.au> * DESCRIPTION (Version): New version is 1.5-1. * src/solve.QP.f, src/solve.QP.compact.f, man/solve.QP.Rd, man/solve.QP.compact.Rd, R/quadprog.R: Implemented changes proposed by Jason Nielsen <jdn@cs.sfu.ca> to return the Lagrangian. * src/solve.QP.f, src/solve.QP.compact.f: Added some code to calculate a number close to machine precision. If inequality constraints are fulfilled to this precision, they are considered fulfilled. This solves some numerical problems reported in the past (see TalbotKatz.R in /tests) * tests/: added a directory with tests. * DESCRIPTION: Took over maintenance from Kurt Hornink. New version is 1.5-0. Added Type: entry, change license to GPL (>=2). * src/Makevars, src/Makevars.win: latter new, both ensure that the solve.QP*.f files are compiled with SAFE_FFLAGS which seems to be necessary for some platforms. * LICENSE.GPL-2, LICENSE.GPL-3: GPL license files to accompany source but not to be installed. * src/solve.QP.f, src/solve.QP.compact.f: Fixed typo in line after loop 191. Noticed by Phillip Wild <p.wild@uq.edu.au> while porting the code to JAVA. 2009-11-19 Kurt Hornik <Kurt.Hornik@wu.ac.at> * DESCRIPTION (Version): New version is 1.4-12. * README: Update. * R/quadprog.R (solve.QP): Fix typo. 2007-07-12 Kurt Hornik <Kurt.Hornik@wu-wien.ac.at> * DESCRIPTION (Version): New version is 1.4-11.

Had meanwhile fixed Rd syntax problems in man/solve.QP.Rd without a ChangeLog entry. 2001-06-10 Andreas Weingessel <Andreas.Weingessel@ci.tuwien.ac.at> * Changed Version number to 1.4-3 to fit to CRAN 2000-12-27 Andreas Weingessel <Andreas.Weingessel@ci.tuwien.ac.at> * DESCRIPTION (Version): New version is 1.2-4. Minor changes in description file to fit R 1.2.0. Minor changes in the documentation to make better use of the Rd features.
