If you look at the roadmap for our next major ESR (#Thunderbird Supernova, version 115), you'll notice our goal to complete most features is Q4 2022.
That's because we're entering "feature-freeze" by the end of 2022, and then spending several months on polish and refinement.
This should also mean a longer beta-testing period (and yep, we're working hard on official stable and beta #Flatpak channels).
We want Supernova to exceed your expectations. https://developer.thunderbird.net/planning/roadmap
