The latest release series of Herwig++ is 2.5, first released in February 2011. To receive email updates about new releases, please send a blank message to herwig-announce-join@projects.hepforge.org.
The detailed Herwig++ reference manual containing many examples is available at arXiv:0803.0883. The new features that were introduced in versions 2.4 and 2.5 are described in our release note [arXiv:1102.1672].
Another useful reference with much information on the physics background of Herwig++ is the MCnet review paper on Monte Carlo event generators, arXiv:1101.2599.
The Herwig++ tarball contains LoopTools by Thomas Hahn.
2011-11-02: Herwig++ 2.5.2 has been released. It requires ThePEG 1.7.2.
If you use LesHoches input with tau spin correlations, you should switch to using ThePEG 1.7.3 instead. Other users don't need to update.
The main improvements are
As usual, the 'NEWS' files in both source tarballs contain a detailed list of changes. Any questions or comments should be directed to herwig@projects.hepforge.org.
