What makes a great changelog
A changelog isn't a git log. Here's how to write updates your customers actually want to read.
A changelog is one of the highest-leverage things you can publish, and one of the most commonly neglected. Done well, it keeps customers engaged, reduces support load, and reminds everyone — including your own team — how much you ship. Done badly, it's a wall of commit messages nobody reads.
Here's what separates the two.
Write for customers, not for git
The single biggest mistake is treating a changelog like a git log. Your
customers don't care that you "refactored the auth middleware." They care that
logging in is now faster and more reliable.
Translate the change into the outcome:
- Don't write: Bumped dependency and patched edge case in parser.
- Do write: Fixed an issue where long file names could break imports.
Lead with the value
Start each entry with what changed for the reader, then add detail if they want it. A good entry answers "why should I care?" in the first sentence.
Group and label
When you ship a lot, structure helps. Simple categories go a long way:
- New — features that didn't exist before.
- Improved — things that got better.
- Fixed — bugs you squashed.
Ship it on a schedule
Consistency beats completeness. A short update every week builds a habit — for you and your readers — far better than a giant post every quarter that never quite gets written.
The best changelog is the one that actually gets published.
That last point is exactly why we built Changelog Generator: it reads your merged pull requests and drafts a customer-facing update automatically, so "ship it on a schedule" stops depending on someone finding the time to write.
