  The program HiggsSignals confronts the predictions of models with arbitrary
Higgs sectors with the available Higgs signal rate and mass measurements,
resulting in a likelihood estimate. A new version of the program,
HiggsSignals-2, is presented that contains various improvements in its
functionality and applicability. In particular, the new features comprise
improvements in the theoretical input framework and the handling of possible
complexities of beyond-the-SM Higgs sectors, as well as the incorporation of
experimental results in the form of Simplified Template Cross Section (STXS)
measurements. The new functionalities are explained, and a thorough discussion
of the possible statistical interpretations of the HiggsSignals results is
provided. The performance of HiggsSignals is illustrated for some example
analyses. In this context the importance of public information on certain
experimental details like efficiencies and uncertainty correlations is pointed
out. HiggsSignals is continuously updated to the latest experimental results
and can be obtained at https://www.gitlab.com/higgsbounds/higgssignals .
