Abstract
In this contribution, new developments for the Standard Model Higgs-boson decays will be summarized. This addresses extensions of the grids used by {\tt Hdecay} to implement finite NLO mass effects for $H\to gg$ as well as explicit numbers for the branching fraction for the strange-Yukawa induced part of $H\to s\bar s$ together with the related uncertainties. In addition, first results of the strong and weak Dalitz decays of the Higgs-boson decays $H\to s\bar s + g/γ$ are presented. The Dalitz decays define the separation between the Yukawa-induced part and the continuum, that is not induced by the strange-Yukawa coupling, and thus pave the way towards a solid determination of the strange-Yukawa coupling at future $e^+e^-$ colliders, but will also be relevant for solid bounds on the strange-Yukawa coupling at the LHC.

Report
It is not clear to me why the first sentence of the caption of figure 1 still refers to the top-mass effects only, but I do not believe that this minor issue warrants a further iteration of the review process. I will thus recommend that the paper be published in SciPost.

(in reply to Report 1 on 2026-01-21)We thank the referee for carefully reading our manuscript.
In arxiv v4, which we will submit when allowed to do so by the editor, we have fixed the caption of Fig. 1, which now does not refer anymore to the top mass effect (typo).
