Incremented when you make incompatible, breaking API changes.
First, I should assess the scope. A changelog is a core document in software development, but the user might be a developer, a technical writer, a project manager, or someone new to the concept. The article should be comprehensive, covering definition, importance, best practices, format standards like Keep a Changelog, and practical advice. "Long article" suggests maybe 1500+ words.
A common mistake made by junior developers and automated systems is treating a Git commit log as a changelog. These are fundamentally different tools for different audiences. Commit Logs Developers working directly on the code.

If you need to convince your manager or team to care about the changelog, present these arguments:
While automation is great for releases, auto-generating a changelog from commit messages fails spectacularly 90% of the time. Here is why: Incremented when you make incompatible, breaking API changes

For libraries, CLIs, and open-source. It lives next to the README.md . This is non-negotiable for NPM packages or Python libraries. If it isn't in the root, developers will assume you don't care about documentation.
Hyperlinks are oxygen for open source. If you fixed issue #123, link to it. If you merged a PR, link to the contributor's profile. This does two things: link to the contributor's profile.
A changelog should never exist in a vacuum; it must strictly correlate with a project's versioning schema. Most modern software ecosystems utilize to give meaning to version numbers.
