In the specific commit, what seems like a bot or automated script added changelog entries for 3 new versions in a single commit, which is odd for an automated script to do. And only the latest version had the date added.

That actions-user seem to be mostly maintaining the Changelog but the commits does not seem consistent with an automated script. I see a few cases of rewriting previous change log entries or moving entries from one version to another which any kind of automation would not be doing. Seems like human error and poor testing.
