I don't understand the bold sentence in the text:
A changelog has historically included all changes made to a project. The "Keep a Changelog" site instead advocates that a changelog not include all changes, but that it should instead contain "a curated, chronologically ordered list of notable changes for each version of a project" and should not be a "dump" of a git log "because this helps nobody".
From:
https://en.wikipedia.org/wiki/Changelog
Can someone help me figure it out?
