[Herwig-announce] Herwig++ 2.1.1 / ThePEG 1.1.1 have been released

[David Grellscheid]

Dear Herwig++ users,

we would like to announce the first bugfix release of
Herwig++ 2.1.1 and ThePEG 1.1.1.

As usual, you can find the downloads at
   http://projects.hepforge.org/herwig/versions

The main improvements are

  * Fully reproducible, identical events for a given random number seed.
    If you want to combine statistics of several runs, you must now vary
    the seed to avoid double-counting of events.

  * A fix for some occurrences of 'nan' in vertex positions. Thanks to
    Genser for the bug report!

A full list of changes is available in the NEWS file of the downloads.

For any questions, please contact herwig at projects.hepforge.org

With best regards,

   The Herwig++ and ThePEG authors
