This PR significantly changes the APIs for instantiating Ethereum nodes in a Go program. The new APIs are not backwards-compatible, but we feel that this is made up for by the much simpler way of registering services on node.Node. You can find more information and rationale in the design document: https://gist.github.com/renaynay/5bec2de19fde66f4d04c535fd24f0775. There is also a new feature in Node's Go API: it is now possible to register arbitrary handlers on the user-facing HTTP server. In geth, this facility is used to enable GraphQL. There is a single minor change relevant for geth users in this PR: The GraphQL API is no longer available separately from the JSON-RPC HTTP server. If you want GraphQL, you need to enable it using the ./geth --http --graphql flag combination. The --graphql.port and --graphql.addr flags are no longer available.
