• apollo-server-core, apollo-server-express: Upgrade subscriptions-transport-ws dependency and remove unneeded runtime dependency on ws. This should enable you to install Apollo Server without depending on versions of ws vulnerable to CVE-2021-32640. Note that the superficial integration of the unmaintained subscriptions-transport-ws package will be removed in Apollo Server 3; you can also avoid this vulnerability by disabling the built-in subscription support with new ApolloServer({subscriptions: false}) and using a maintained package such as graphql-ws instead. (Instead of taking this upgrade, you can also upgrade ws to 5.2.3, which was just released.)

• apollo-server-core: You may now specify your Studio graph as a graph ref (id@variant) via the APOLLO_GRAPH_REF environment variable or new ApolloServer({apollo: {graphRef}}) instead of specifying graph ID and graph variant separately. The apollo object passed to plugin serverWillStart and to gateway load now contains a graphRef field.
• apollo-server-core: Fix a race condition where schema reporting could lead to a delay at process shutdown. PR #​5222
• apollo-server-core: Allow the Fetch API implementation to be overridden for the schema reporting and usage reporting plugins via a new fetcher option. PR #​5179
• apollo-server-core: The server.executeOperation method (designed for testing) can now take its query as a DocumentNode (eg, a gql-tagged string) in addition to as a string. (This matches the behavior of the apollo-server-testing createTestClient function which is now deprecated.) We now recommend this method instead of apollo-server-testing in our docs. Issue #​4952
• apollo-server-testing: Replace README with a deprecation notice explaining how to use server.executeOperation instead. Issue #​4952

• apollo-server-core: Apollo Studio usage reporting uses a more efficient format which sends fewer detailed traces to Apollo's server. This change should not have a major effect on the experience of using Apollo Studio. PR #​4142
