Rebuilt from the ground up, around Klevu's new JSON indexing APIs, with a focus on Magento best practices and ease of customisation.

## Compatibility

Klevu's Magento v4 plugin will support the officially supported version of PHP and Magento. i.e. when PHP 8.1 reaches end-of-life Klevu will also drop support for PHP 8.1 in future releases. Previous releases will always be available via Github and Packagist.

- **Adobe Commerce**: `2.4.4` - `2.4.8-p1`.
- **Magento Open Source**: `2.4.4` - `2.4.8-p1`.
- **PHP**: `8.1` - `8.4`.
- **Hyvä Themes.**

## Recommended Customisation Methods

Customisation should be implemented through one of the following methods

- plugins
- events and observers
- injecting classes via `di.xml` 

**Avoid extending Klevu classes via preferences**.

:::hint{type="warning"}
If you find yourself extending a Klevu class to customise our modules please reach out to support. Either there is a better way to achieve your aims or we have not architected that area as we should have done.
