I'm going to present the recent developments in the Planck HFI reanalysis, a continuation of the Planck LFI reanalysis completed by the BeyondPlanck collaboration. Particularly I will discuss new Bayesian approaches in the bolometer transfer function deconvolution, and its effects on the noise level.
