Thanks, we don't always have the time to "diff" a build configuration for a major upgrade of webpack. Nice summary. :)
BTW, using module lazy loading, it used to need a well configured serie of plugins to avoid hash changing all the time for each chunk, even without code changes. Have you checked that hashes are constant?

Interesting, I just verified, the hashes do stay consistent through multiple builds as long as the contents don't change.

Might be some other that plugin may be constantly changing something in your build or just a bug in Webpack that probably got fixed in later versions.

Theres hash and contenthash. The latter is computed from chunk content (is deterministic, i hope), so the same input gives same output. Hash is global for the build afair.
