About

ForeverDiff is an independent, per-build record of what changes in the World of Warcraft client between Classic Era and World of Warcraft: Forever. It exists because the data is public and machine-readable, but nobody publishes the diff itself as a browsable, cited ledger.

It is built and maintained by the Vient team. We are not affiliated with Blizzard Entertainment. We publish records, not opinions: verbatim values from the game client, with the build they came from, and never a grade or a "best" verdict.

Our sources and checks are described in the methodology. If a value here is wrong, please tell us: see corrections.
