We examine further the ability of the New Early Dark Energy model (NEDE) to
resolve the current tension between the Cosmic Microwave Background (CMB) and
local measurements of ${H}_{0}$ and the consequences for inflation. We perform new
Bayesian analyses, including the current datasets from the ground-based CMB
telescopes Atacama Cosmology Telescope (ACT), the South Pole Telescope (SPT),
and the BICEP/Keck telescopes, employing an updated likelihood for the local
measurements coming from the S${H}_{0}$ ES collaboration. Using the S${H}_{0}$ ES prior
on ${H}_{0}$ , the combined analysis with Baryonic Acoustic Oscillations (BAO),
Pantheon, Planck and ACT improves the best-fit by $\mathrm{\Delta}{\chi}^{2}=-15.9$ with
respect to $\mathrm{\Lambda}$ CDM, favors a non-zero fractional contribution of NEDE,
${f}_{\mathrm{N}\mathrm{E}\mathrm{D}\mathrm{E}}>0$ , by $4.8\sigma $ , and gives a best-fit value for the Hubble
constant of ${H}_{0}=72.09$ km/s/Mpc (mean ${71.48}_{-0.81}^{+0.79}$ with $68\mathrm{\%}$
C.L.). A similar analysis using SPT instead of ACT yields consistent results
with a $\mathrm{\Delta}{\chi}^{2}=-23.1$ over $\mathrm{\Lambda}$ CDM, a preference for non-zero
${f}_{\mathrm{N}\mathrm{E}\mathrm{D}\mathrm{E}}$ of $4.7\sigma $ and a best-fit value of ${H}_{0}=71.77$ km/s/Mpc
(mean ${71.43}_{-0.84}^{+0.84}$ with $68\mathrm{\%}$ C.L.). We also provide the
constraints on the inflation parameters $r$ and ${n}_{s}$ coming from NEDE,
including the BICEP/Keck 2018 data, and show that the allowed upper value on
the tensor-scalar ratio is consistent with the $\mathrm{\Lambda}$ CDM bound, but, as also
originally found, with a more blue scalar spectrum implying that the simplest
curvaton model is now favored over the Starobinsky inflation model.
