# Packages and changelogs

The latest official Mangopay SDK releases are published on the relevant package management platform for each language. The changelogs of each release are published below, as well as the integration guides.

## Server-side SDKs

<Warning>
  **Caution – Use only the mangopay4 packages (late Nov 2025)**

  Please ensure you use **only** the packages with **mangopay4** in the name (this is the package name and has no connection with the SDK version number).

  **Any other package must not be used.** You need to update your package manually.

  Since November 25, 2025, Mangopay's official SDKs are no longer accessible on GitHub (with the exception of PHP for publication reasons).
