<Note>

Before you increment a subgraph's federation version, update your router and build pipeline. For details, see [Updating your graph safely](/graphos/platform/graph-management/updates).

</Note>

- If you maintain a [subgraph-compatible library](/graphos/reference/federation/compatible-subgraphs), consult this article to stay current with recently added directives. All of these directive definitions are also listed in the [subgraph specification](/graphos/reference/federation/subgraph-spec/#subgraph-schema-additions).
