Changelog
The changelog lists every change to the application, in two layers.
Two layers
The top layer is a plain-language summary of what changed and why it matters. Expanding an entry reveals the receipt chain underneath: the commit, the build, the deploy, and the elapsed time from push to live.
Most changelogs ask you to trust a summary. This one lets you check it, which is the entire point of publishing it.
Verifying an entry
Each entry links to its commit. From the commit you can read the diff, and the receipts tell you when that exact revision went live.
What is not published
Disclosure is per-repository. An entry may show that a change happened and what class it belonged to while withholding the diff, if that repository serves at a lower level.
