  We present the third release of the CLUMPY code for calculating $\gamma$-ray
and $\nu$ signals from annihilations or decays in dark matter structures. This
version includes the mean extragalactic signal with several pre-defined options
and keywords related to cosmological parameters, mass functions for the dark
matter structures, and $\gamma$-ray absorption up to high redshift. For more
flexibility and consistency, dark matter halo masses and concentrations are now
defined with respect to a user-defined overdensity $\Delta$. We have also made
changes for the user's benefit: distribution and versioning of the code via
\git{}, less dependencies and a simplified installation, better handling of
options in run command lines, consistent naming of parameters, and a new Sphinx
documentation at http://lpsc.in2p3.fr/clumpy/.
