Patchlog – Embedded changelog widget with Markdown support

Summary: Patchlog is a lightweight changelog widget embedded via a single script tag that displays release notes inside web apps. It supports Markdown editing, scheduled publishing, and provides a hosted public changelog page with RSS feed options.

What it does

Patchlog adds a floating "What's new" button to web apps, showing structured release notes written in Markdown. It offers immediate or scheduled publishing, theme customization, and style isolation using Shadow DOM.

Who it's for

Developers and product teams who want to communicate updates directly within their web applications without complex setup.

Why it matters

It ensures users see release notes inside the app rather than in separate blogs or emails, improving update visibility and engagement.
