# 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!
