# Gutenberg version 3 🎉

From version ^3.0.0 and above, all **Ncmaz Gutenberg blocks** have an additional option \[**Has SSR Init Data]**

<figure><img src="/files/tcubLC7D5sPM0LvZjhZf" alt=""><figcaption><p><strong>Has SSR Init Data option</strong></p></figcaption></figure>

From versions prior to 3.0, all **ncmaz gutenberg blocks** will fetch data via Graphql on the client side, which makes the site feel slow. However, from version ^3.0, when you enable the "***Has SSR Init Data***" option, the block data will be returned from the server without having to request graphql on the client side anymore.

However, you should not abuse this, our advice is that you only enable this option for the first few blocks that appear on the page, and for the following blocks, you should turn this option off to maximize your power Strength of lazy loading (Only loads data when the user scrolls near the block).

Hope it is useful to you... Best regards!

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://nghiaxchis.gitbook.io/ncmaz-wordpress/gutenbergs/gutenberg-version-3.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
