Old versions

Back to Function index. Up to Contents.

List of versions in reverse chronological order together with a brief list of changes. (Note: Old versions of the library use a year-month style of numbering. Now, the library uses a major and minor version number.) Recent versions of RandomLib are available at http://sourceforge.net/projects/randomlib/files/distrib/. Older versions are in http://sourceforge.net/projects/randomlib/files/distrib/archive/.

The corresponding documentation for these versions is obtained by clicking on the “Version m.nn” links below. Some of the links in the documentaion of older versions may be out of date (in particular the links for the source code will not work if the code has been migrated to the archive subdirectory). All the releases are available as tags “rm.nn” in the the "release" branch of the git repository for RandomLib.

• Version 1.10 (released 2014-11-22)

    • tweaks to the cmake build support and the documentation;
    • strengthen the advice to use C++11.

    • find_package (RandomLib ...) requires that RandomLib be capitalized correctly;
    • on Unix/Linux, don't include the version number in directory for the cmake configuration files;
    • defaults for RANDOMLIB_DOCUMENTATION is now OFF;
    • the configuration parameters PACKAGE_PATH and INSTALL_PATH are now deprecated (use CMAKE_INSTALL_PREFIX instead).

• Version 1.4 (released 2012-02-21)
  • Add MPFR interface.

  • Change RandomNumber to a signed-magnitude representation; this results in slight incompatibilities in the interface.
  • A tweak to ExactNormal to minimize the number of digits generated.
  • Improve efficiency of ExactExponential.

  • Add internal documenation to the cmake configuration files.
• Version 1.2 (released 2011-12-20)
  • Change license to MIT/X11.
  • Add ExactNormal class. This enables you to sample exactly from a normal distribution with zero mean and unit variance (assuming that the underlying generator is perfect).

  • Convert parallelization example, RandomThread.cpp, to OpenMP.
  • Migrate source from subversion to git.
• Version 2011-05 (released 2011-05-17)
  • INCOMPATIBLE CHANGE: the default constructor Random r; sets the seed to []. Use r.Reseed(); to reset the seed to Random::SeedVector();
  • Make sure Global generators are exported to the dll.
• Version 2011-04 (released 2011-04-12)
  • Use cmake for configuration.
  • Improve documentation on installation process.
  • Improve documentation of parallelization.
  • Remove examples RandomPermutation and shuffle and add RandomCoverage, RandomExact, RandomLambda, RandomSave, and RandomThread.
  • Add specialized swap.
  • Ensure the code works with compilers with no long double type.
  • Add new and delete operators for SFMT19937 under Visual Studio.
• Version 2010-01 (released 2011-01-11)
  • Move to SourceForge.
• Version 2009-02 (released 2009-02-10)
  • RandomPermutation and shuffle accept -r option to undo a permutation or shuffle.
  • Minor documentation fixes.
• Version 2008-11 (released 2008-11-10)
  • Changes to suppress warnings with g++ 4.3.
  • Optional support for C++11's static_assert.
  • Document RandomPermutation and shuffle.
  • Minor documentation fixes.
• Version 2008-04 (released 2008-04-28)
  • Reorganized so random algorithm and mixer can be selected independently. This eliminated a lot of duplicate code.
  • This requires a new, incompatible, output format. Format is now independent of the current base of the stream.
  • Name() now returns more informative name.
  • SFMT19937 init_by_array mixer adopted for MT19937 generators. This is an incompatible change for the MT19937 generators. However it is possible to hook the MT19937 engine with the MixerMT1 mixers to recover the previous functionality using
    • RandomEngine<MT19937<Random_u32>, MixerMT1<Random_u32> >
    • RandomEngine<MT19937<Random_u64>, MixerMT1<Random_u64> >
  • The way 32-bit results are glued together for to provide the Ran64() result is now LSB ordered. Previously the 32-bit version of MT19937 used MSB ordering here. This means that certain large integer results will be different for RandomEngine<MT19937<Random_u32>, MixerMT1<Random_u32> >
  • Support AltiVec instructions on PowerPC for SFTM19937. Also use longer long double on PowerPC.
  • Add -s seed option to shuffle and RandomPermutation.
  • Use strtoull (where available) instead of strtoul in convert a string seed to numeric form.
  • Switch project files to MS Visual Studio 2005.
  • Use SeedVector() instead of SeedWord() for the default constructor for Random.
  • Make 32-bit version of SFMT19937 the default generator.
• Version 2008-01 (released 2008-01-07)
  • This is a maintenance release in anticipation of a forthcoming major restructuring of the code.
  • Use table of powers of two for g++ 4.1.
  • Minor documentation fixes.
• Version 2007-05 (released 2007-05-21)
  • Add SFMT19937 generators.
  • Introduce RandomGenerator::Name() to identify generator.
  • Change define used to make 64-bit generator the default.
  • Add RandomSelect::Weight.
  • Ensure portability to systems where uint32_t is longer than 32 bits.
• Version 2007-04 (released 2007-04-12)
  • Add utilities RandomPermutation and shuffle.
  • Implement MSB ordering on binary I/O in a portable way.
• Version 2006-12 (released 2006-12-05)
  • Add leapfrogging. The output format needed to be changed to accommodate an extra word of data. However, I/O routines can still read the 2006-11 version.
• Version 2006-11 (released 2006-11-02)
  • Introduce RandomCanonical class which accepts the random generator as a template argument.
  • This allows the inclusion of 32-bit and 64-bit versions of mt19937.
  • Include checksum in I/O.
  • Include boost serialization.
• Version 2006-10 (released 2006-10-05)
  • Make 64-bit ready so a 64-bit version of mt19937 can be dropped in.
  • Fix a bug in the seeding. (This bug was triggered by seed length of 624 or greater; so it was unlikely to have been encountered in practice.)
  • Stop the special case treatment for Random::IntegerC<T>(numeric_limits<T>::max()). In some cases (e.g., T = int) this now gives different (but equivalent) results.
• Version 2006-09
  • Add ExponentialProb, ExactExponential, ExactPower, and RandomNumber.
  • Fix weakness in the seeding algorithm. A given seed now gives a random sequence different from previous version; so this is an incompatible change.
  • Restructure the documentation.
  • Allow constructors to accept vectors of any integral type and constructors with a pair of iterators.
• Version 2006-08 (released 2006-08-17)
  • Improve efficiency of Integer(n) where n is a power of two.
