[Rivet-announce] Rivet 2.6.0 and YODA 1.7.0 released

[Andy Buckley]

Dear all,

Right down to the last minute before Christmas, we're *very* happy to
finally announce the release of Rivet 2.6.0. It's been 6 months since the
last release, since we skipped version 2.5.5 at the 3-month point in favour
of this release, but there should be enough improvements to make it worth
the wait.

This major release heralds several new analyses, and minor improvements and
bugfixes, but also lots of important stuff behind the scenes:

-
​ ​
Rivet (and YODA) can now read and write gzipped HepMC and YODA files :-)

-
​ ​
Addition of a recursive composite structure to Particle, which enables a
lot of cool stuff and is taking us toward an even more unified picture of
particles and jets in the Rivet framework, although the latter is not there
yet.

-
​ ​
A new analysis build system, making builds faster and more uniform, and
integration of contrib analyses *much* easier.

-
​ ​
Lots of extensions to the filtering and functors system, and improvements
to the detector parametrisation and machinery. In particular there's now a
very lightweight way to pass multiple smearing/efficiency functors in a
list, and they'll be executed sequentially through a uniform interface.

This version (with YODA 1.7.0, released at the same time) is recommended
for immediate production use. Have fun!
As always they are available from https://rivet.hepforge.org/ and
https://yoda.hepforge.org/​


Merry
​ ​
Christmas!
The Rivet/YODA team
