How to add a changelog to any web app with one script tag

Short summary

The article argues that shipping code without visible changelogs creates a costly perception gap where users feel a product is abandoned even when it's actively updated. It recommends an in-app "what's new" widget implemented via a single script tag with Shadow DOM isolation and silent failure handling, rather than a standalone changelog page nobody visits. The author discloses they built Patchlog, the tool featured in the snippet, but the integration pattern and writing-discipline advice apply to any changelog solution.

• •An in-app changelog widget closes the gap between shipping and users noticing updates
• •Implementation should use Shadow DOM for style isolation and fail silently to protect the host app
• •Write small, frequent, human-sounding updates tagged as New/Fixed/Improved to convey momentum
