<li>Instant search — Quickly find articles from the sidebar as you type.</li>

<li>Translation-ready — Includes English language files and a translation template for other languages.</li>
</ul>
<h3>Usage</h3>
<h4>Documents</h4>
Add your documentation articles in DevDocs and assign them to one or more Topics so they appear in the right place in the sidebar. Use Order if you want to control which articles appear first.
<h4>Topics</h4>
Use Topics to build your sidebar structure. You can create main sections and place sub-sections inside them, then use Order to control how they are listed.
<h4>Changelog</h4>
Each changelog entry supports: 
* A Version Number and Release Date. 
* A summary description. 
* Update items grouped as Added, Changed, Fixed, Removed, Deprecated, or Security.
<h4>Settings</h4>
Navigate to DevDocs → Settings to configure:
<ul>
<li>Documentation Page — The WordPress page that renders the docs layout.</li>
<li>Documentation Name — Label shown in the sidebar header.</li>
<li>Welcome Heading / Message — Text displayed on the overview screen.</li>
<li>Show Topic Cards — Toggle topic card grid on the welcome screen.</li>
<li>Show Latest Update — Toggle the latest changelog snippet on the welcome screen.</li>

ThemeZee

The WP Theme Changelogs plugin allows you to view the changelog before updating a theme, very similiar to the available changelogs for plugins.
<h4>How does this work?</h4>
The plugin parses the readme.txt of the theme to get the changelog details. In order to work, your theme must have a valid readme.txt including a changelog section.

Excellent idea! Thank you for making this possible. Keep up the good stuff!


Now we got real rock & roll! :P

Hace lo que promete. Ojalá pronto sea obligado poner los changelogs en archivos readme.txt en el directorio de temas.

Y sino que se incluya esta funcionalidad en el núcleo de WP

Funciona perfecto
