  New Early Dark Energy introduces a new phase of dark energy that decays in a
fast-triggered phase transition around matter-radiation equality. The presence
of a trigger mechanism sets it apart from other early dark energy models. Here,
we will argue that New Early Dark Energy offers a simple and natural framework
to extend $\Lambda$CDM while also providing a pathway to resolving the $H_0$
tension alongside its smaller cousin, the $S_8$ tension. At the microscopic
level, we discuss the possibility that the trigger is either given by an
ultralight scalar field or a dark sector temperature. In both cases, it prompts
the transition of an $\mathrm{eV}$-mass scalar field from its false to its true
minimum. Furthermore, we argue that the same phase transition could give rise
to a dynamic process for generating neutrino masses.
