Dear users of Herwig and ThePEG,

we're happy to announce the first bug-fix release in the Herwig 7 
series, Herwig 7.0.1, with the matching release of ThePEG 2.0.1. In 
future, we aim to release bug fixes every 4-8 weeks, incrementing the 
third digit of the version number.

The latest version of the bootstrap script at

   https://herwig.hepforge.org/herwig-bootstrap

will update ThePEG and Herwig in an existing bootstrap installation.

As always, contact <herwig at projects.hepforge.org> with any questions or 
comments, or use our newly re-opened bug tracker at

   https://herwig.hepforge.org/trac/

with user name "new" and password "ticket". Don't forget your email 
address in the CC field!

With best regards,

   The Herwig developers
