webpack version differences?

[ghost]

In the package.json I see webpack next; what version does that specifically point to? I think for a benchmark, especially in the rapidly evolving world of JS tools, to be specific so that a better comparison can be had.

For example, the computer language shoot out does this for each benchmark suite: https://benchmarksgame.alioth.debian.org/u64q/nbody.html

They show Rust with 3 different programs; I think it makes sense to show webpack at 2 different versions, next and whatever is the currently used version. Same with parcel, maybe pick latest + current production standard version?
