+## Relay Binary
+
+Every release of Relay also provides a set of binaries that come with a minimum required OS version.
+
+| Operating System  | Version   |
+| Ubuntu x86        | 20.04     |
+| Ubuntu ARM        | 22.04     |
+| MacOS             | macOS Sonoma (version 14)     |
+| Windows           | Windows Server 2019   |
+
+We support LTS versions of the listed Operating Systems as long as they receive updates from their vendors.
+The only exception is Ubuntu x86, which will be supported 2 years after LTS support has officially ended to allow
+customers with extended support to continue using Relay.
