# Server-Transformer Compatibility

Before October 30, 2024, [`rudder-server`](https://github.com/rudderlabs/rudder-server/) was compatible with **any** version of `rudder-transformer`.

Going forward, the `rudder-server` releases will have a dependency on specific minimum required versions of `rudder-transformer` and vice versa - allowing the team to focus on releasing high quality integrations and reducing the maintenance of older implementations.

{{< warning >}}
To avoid any breaking changes to your pipelines, use the latest **minor** releases of [`rudder-server`](https://github.com/rudderlabs/rudder-server/releases) and [`rudder-transformer`](https://github.com/rudderlabs/rudder-transformer/releases).
