arpack-ng - 3.6.0

 [ Franck Houssen ]
 * Add support for ISO_C_BINDING (Fortran 2003) for ARPACK, PARPACK (Fortran <-> C/C++).
   ARPACK:  example of   C/Fortran binding can be found in the         TESTS/icb_arpack_c.c          file.
   ARPACK:  example of C++/Fortran binding can be found in the         TESTS/icb_arpack_cpp.cpp      file.
   PARPACK: example of   C/Fortran binding can be found in the PARPACK/TESTS/MPI/icb_parpack_c.c     file.
   PARPACK: example of C++/Fortran binding can be found in the PARPACK/TESTS/MPI/icb_parpack_cpp.cpp file.
   DEBUG:   add support for debug.
   STAT:    add support for statistics (timers, nb operations, ...).
 * Provide tarball generation using cmake (cpack).
 * Provide find_package for (cmake) users to find arpack-ng.

 [ Denis Davydov ]
 * Rename pslamch to pslamch10 to avoid symbol collision with Scalapack 2.0.2 in MPI context.

 [ Kyle Guinn ]
 * Autoconf cleanup; move generated files to the build-aux subdirectory.

 [ Marco Caliari ]
 * Force the initial residual to be in the range of the operator OP in the standard case, too (Closes: #79).

 [ Sylvestre Ledru ]
 * Add coverage information to improve testing: https://coveralls.io/github/opencollab/arpack-ng

 [ Darcy Beurle]
 * Add C++11 interface through arpack.hpp and parpack.hpp
 * Rewrite C++ examples / tests demonstrating new C++11 interface
 * Pre-C++11 interface available through arpack.h and parpack.h

arpack-ng - 3.5.0

 [ Julien Schueller ]
 * Improve cmake build system: disable C++ detection, set default build type.

 [ Marco Atzeri]
 * Use AC_PROG_FC instead of AC_PROG_F77 for proper inizialization
   for the usage of AC_FC_LINE_LENGTH. Noted on Cygwin.

 [ Denis Davydov ]
 * Improve cmake build system: add make install and fix shared libraries.

 [ Zhang Z ]
 * fix usages of DLACPY to not alias inputs
   (patch from https://software.intel.com/en-us/articles/how-to-resolve-arpack-issues-with-intel-mkl-110-update-3)

 [ Iskakov Sergei ]
 *  Fix possible deadlock when PARPACK call uses communicator with a larger
    number of CPUs than previous call

 [ Kyle Guinn ]
 * Portability improvements to the autotools build system.
 * Let cmake guess the default installation directories.  Can be
   overridden by changing CMAKE_INSTALL_LIBDIR and CMAKE_INSTALL_BINDIR.
 * Shared libraries built by cmake now have their SONAME set identical to
   those built by autotools.

 [ Marco Caliari ]
 * Avoid purification stage in [d,s]neupd.f if it requires division
    by zero (Closes: #58)

arpack-ng - 3.4.0

  [ Milan Bouchet-Valat ]
  * Allow adding suffixes to symbols and library names to build ILP64 version
    based on ILP64 BLAS/LAPACK with suffixes. This avoids conflicts when loading
    libraries with different integer sizes in the same program.

  [ Martin Reuter ]
  * Add the support of cmake build system

 -- Sylvestre Ledru <sylvestre@debian.org>  Sat, 02 Jul 2016 21:51:52 +0200

 [ Kyle Guinn ]
 * General improvements on the build system
 * libparpack links against libarpack (instead of doing a static link)

 [ Guillaume Horel ]
 * reverts using {d,s}lahqr from lapack 2
 * use dlahqr from lapack 3 instead of dlaqrb (credit to Marco Caliari)

 -- Sylvestre Ledru <sylvestre@debian.org>  Mon, 12 October 2015 08:40:51 +0200

arpack-ng - 3.2.0

 -- Sylvestre Ledru <sylvestre@debian.org>  Sat, 15 Feb 2014 14:24:42 +0200

arpack-ng - 3.1.4

 * libparpack2: missing dependency on MPI:
   http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=718790

 * Replace LAPACK second function with ARPACK's own arscnd in PARPACK

 * Fix issue #1259 in DSEUPD and SSEUPD
   The Ritz vector purification step assumes workl(iq) still contains the
   original Q matrix. This is however overwritten by the call to xGEQR2
   earlier.
   .
   This patch fixes the issue by making a copy of the last row of the
   eigenvector matrix, after it is recomputed after QR by xORM2R. The work
   space WORKL(IW+NCV:IW+2*NCV) is not used later in the routine, and can
   be used for this.

 * Use configure supplied blas and lapack in the pkg-config.
   Thanks to Ward Poelmans (Closes: #1320)

 * Switch to automake 1.14 + libtool 2.4.2.
   Thanks to Ward Poelmans (Closes: #1321)

 * dseupd routine may lead to a segmentation fault
   Thanks to Edouard Canot (Closes: #1323)

 * dsaupd and 'BE' option returns wrong eigenvalues for a SPD matrix
   Thanks to Edouard Canot (Closes: #1329)

arpack-ng - 3.1.0

   * Many bug fixes in the parpack lib. It is an old patch from upstream.
     Thanks to Viral Shah for pinging us on this subject.
     See the PARPACK_CHANGES file for the details.
   * Change the bug report from arpack@caam.rice.edu to
     http://forge.scilab.org/index.php/p/arpack-ng/issues/
   * Provide a M4 macro (detect_arpack_bug.m4) to check if the underlying
     arpack is buggy (ie not arpack-ng). This allows developer applications
