  Lilith is a public Python library for constraining new physics from Higgs
signal strength measurements. We here present version 2.0 of Lilith together
with an updated XML database which includes the current ATLAS and CMS Run 2
Higgs results for 36/fb. Both the code and the database were extended from the
ordinary Gaussian approximation employed in Lilith-1.1 to using variable
Gaussian and Poisson likelihoods. Moreover, Lilith can now make use of
correlation matrices of arbitrary dimension. We provide detailed validations of
the implemented experimental results as well as a status of global fits for
reduced Higgs couplings, Two-Higgs-doublet models of Type I and Type II, and
invisible Higgs decays. Lilith-2.0 is available on GitHub and ready to be used
to constrain a wide class of new physics scenarios.
