Rivet release 2.1.1

This version updates the Rivet 2.1.0 analysis content to contain four new analyses (two each from ATLAS and CMS: see the analysis content diff page), and providing better tools for Particle/Jet sorting (e.g. a new sortByPt() function for Jets and Particles vectors) and querying Particles about their decay products.

We are very happy to announce the release of the third Rivet version in the 2.x series, version 2.1.1.

This version updates the Rivet 2.1.0 analysis content to contain four new analyses (two each from ATLAS and CMS: see the analysis content diff page), and providing better tools for Particle/Jet sorting (e.g. a new sortByPt() function for Jets and Particles vectors) and querying Particles about their decay products. Access has been provided to the YODA analysis object collection via the AnalysisHandler interface.

There are of course also bug-fixes and as always we encourage everyone to upgrade immediately. Installation requires the new YODA version 1.0.6, released at the same time. Build scripts for LCG and stand-alone systems are available: check the “Getting started” doc page.

We intend to continue with more 2.1.x minor releases to provide analysis updates as rapidly as practically possible. The next major release will be version 2.2.0, in which the jet, histogram, and kinematic cuts systems will be significantly upgraded.
