The latest release series of Herwig++ is 2.6, first released in May 2012. 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]. The release note [arXiv:1205.4902] describes the new features in version 2.6.
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.
Examples of the results of Herwig++ compared to LEP, Tevatron jet, Tevatron W/Z, Tevatron photon production, Star, LHC jet, LHC W/Z, LHC photon production, HERA, CERN SppS and ISR and B-factory data made using Rivet are also available.
The Herwig++ tarball contains LoopTools by Thomas Hahn.
2013-02-22: Herwig++ 2.6.3 has been released. It requires ThePEG 1.8.3.
The main improvement in this small bug fix release is a fix for some broken displaced vertices. In some circumstances, internal technical vertices that only changed a particle's momentum caused a displacement to occur. Thanks to ATLAS for the bug report!
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.
Please respect the MCnet guidelines for Event Generator authors and users.
