Speaking to the lifetime of each major version—Bootstrap 4 can't go into any kind of LTS situation until v5 is fully stable. That's going to take a few months just being honest, so I fully expect v4 to be around into 2021.

We've also maintained security patches and more for v3 where appropriate well past the LTS for the web's sake. While we try to have guidelines around it, we want to help move things forward for the web :).

THANK YOU for keeping version 3 alive.
