[Herwig-announce] Herwig++ 2.4.1 and ThePEG 1.6.0 have been released

[David Grellscheid]

Dear Herwig++ and ThePEG users,

we would like to announce the release of ThePEG 1.6.0 together with
Herwig++ 2.4.1.

The main new features in ThePEG are

- A reworked helicity amplitude framework, which makes writing model
vertices easier.
- Easier handling of decay mode names in input files: the ordering of
decay products is free.
- ThePEG's repository command language includes a 'help' functionality.

The main new features in Herwig++ are

- Soft QED radiation in Z decays is fully 1-loop by default.
- Soft QED radiation is enabled in BSM decays and all perturbative
decays by default.
- Spin correlations are switched on by default for all perturbative decays.
- The scale choice for Powheg and BSM processes can be chosen in the
input files.
- All file output (except for analyses) can be redirected to stdout.
- SLHA output for internally calculated SUSY branching ratios.
- A model for transplanckian scattering.

Many other improvements have been made, please read both the 'NEWS'
files for the detailed list of changes. Some of the changes may need
small modifications to user code. Please contact us if you have problems!
