# Introduction to Release Candidates

<Info>
  The **2027-01 Release Candidate** is now available. It will become the next stable release in **January 2027**.
</Info>

## Release Candidate version

A Release Candidate (RC) is a production-ready version of the upcoming stable API. It gives you the opportunity to integrate early — before the official stable release — with no migration effort when the stable version ships.

The RC and the upcoming stable version share the same URL. If you integrate `2027-01` now, you are already on the right version the moment it goes stable — zero migration effort.

This version can be called using `2027-01` as the version identifier:

```http theme={null}
https://api.criteo.com/2027-01
```
