Ember is working through a migration replacing their build system and bundler with Vite -- all while maintaining backwards compatibility to a version released in 2021. Ember will be fun to watch in the coming year.
Depending on how you count it that could be a version originally released in 2018 i.e. the version they are aiming to support is 3.28 which you should be able to easily update to from 3.0 (which was released in 2018) since it's a minor update with no breaking changes
