+
+Adding a changelog page to your docs is as simple as adding an MDX file with [Update components](/components/update).
+
+Check out the [Mintlify changelog](/changelog) as an example: you can include links, images and text content, and demos of your new product features in each update.
+
+# Tag filters
+
+Adding tags to your Update components will make a tag list appear on the right side of your changelog document which can be used for filtering Update items:
+
+```mdx
+<Update label="v0.0.10" tags={["Wintergreen", "Spearmint"]}>
+  Lorem ipsum dolor sit amet, consectetur adipiscing elit...
+</Update>
+
+<Update label="v0.0.09" tags={["Spearmint"]}>
+  Nam fermentum ultricies ipsum, pellentesque pellentesque purus facilisis non...
+</Update>
+
+<Update label="v0.0.08" tags={["Wintergreen", "Peppermint"]}>
+    Donec viverra risus lacinia, tincidunt magna mattis, pulvinar magna...
+</Update>
+```

+
+# Subscribable changelogs
+
+Using the Update component on your changelog page also automatically creates a subscribable RSS feed for your changes at the page URL + "/rss.xml"
+
+After publishing a new Update on the page, it will be automatically included in the RSS feed for that page. RSS feeds can be integrated with Slack, email, or other subscription tools for your users. 
+
+You can customize the text included for each Update item with the feedTitle and feedUpdate properties: 
+
+```mdx
+<Update label="v0.0.10" rss={title: "Version 0.0.10 is now live", description: "Including updates to AI models and more"} feedDescription=>
+  Lorem ipsum dolor sit amet, consectetur adipiscing elit...
+</Update>
+```
