# DOPP Version History

Our [Discounts on Product Page](/en/article/how-to-display-discounts-on-product-pages-1sj49lh/) (DOPP) feature has multiple versions. This article states the differences and helps you determine which version you're on.

## Why are there multiple versions?
Simply put - as our team learned more about Shopify and saw more stores' setups, we made changes to either add more functionality or to simplify setup.

## Versions
* **DOPP v1**: Our first version. Totally Liquid based, but it has [major limitations](/en/article/limitations-of-the-discounted-price-block-1y3qhdd/).
* **DOPP v2**: Enabled the app to display discounts on collection pages, search pages, and more, but it had a complex setup requiring manually adding app blocks to every template. Required a [move to JavaScript](/en/article/why-do-you-use-javascript-instead-of-a-liquid-snippet-1ckcasu/).
* **DOPP v3**: All the benefits of DOPP v2, but it doesn't require any app blocks (only 1 app embed). Settings are detected automatically, and you can edit them directly in our app.

## Which version am I on?
* You're on **DOPP v3** If you have the new "Display Discounts" embed enabled.
* You're on **DOPP v2** If you have the legacy "Discounts Embed" embed enabled, or the "Collection Page Discount," "Product Page Discount," "Recommendations Discount," or "Search Page Discount app block(s) enabled.
* You're on **DOPP v1** if you are using the "[DEPRECATED] Legacy Discounted Price" app block, AND have neither the "Display Discounts" nor the "[DEPRECATED] Legacy Discounts Embed" app embed(s) enabled.
