[Rivet] Check CMS double parton scattering and 4 jet correlations codes

[Andy Buckley]

Hi again,

We will be releasing Rivet 2.1.1 today -- please shout now if you see
something problematic in your analyses as linked below, and/or let us
know post-release if you find functional problems.

Best wishes,
Andy et al
