<View title="Developer" />

<View title="EU docs" />

This topic explains LaunchDarkly's Relay Proxy versioning policy, which is based on the semantic versioning standard.

To learn more, read [Semantic Versioning 2.0.0](http://semver.org/).

## Versioning policy

The Relay Proxy's versioning policy matches that of LaunchDarkly's SDKs. To learn more, read [Versioning policy](/docs/sdk/concepts/versioning).

## Supported versions

The Relay Proxy follows LaunchDarkly's end of life (EOL) policy to determine each version's maintenance window. The end of life policy also defines when the Relay Proxy can drop support for older versions of its underlying platform (Go).
