+Simply remove the `/lib/` part from your graphql-ws imports that use a handler.

+Client is truly zero-dependency, not even a peer dependency on `graphql`
+
+In non-browser environments, you can use only the client and not even depend on `graphql` by importing from `graphql-ws/client`.
+
+```ts
+import { createClient } from 'graphql-ws/client';
+
+const client = createClient({
+  url: 'ws://localhost:4000/graphql'
+});
+```
+
+Note that, in browser envirments (and of course having your bundler use the [`browser` package.json field](https://docs.npmjs.com/cli/v11/configuring-npm/package-json#browser)), you don't have to import from `graphql-ws/client` - simply importing from `graphql-ws` will only have the `createClient` available.

+`onSubscribe`, `onOperation`, `onError`, `onNext` and `onComplete` hooks don't have the full accompanying message anymore, only the ID and the relevant part from the message
+
+There is really no need to pass the full `SubscribeMessage` to the `onSubscribe` hook. The only relevant parts from the message are the `id` and the `payload`, the `type` is useless since the hook inherently has it (`onNext` is `next` type, `onError` is `error` type, etc).
+
+The actual techincal reason for not having the full message is to avoid serialising results and errors twice. Both `onNext` and `onError` allow the user to augment the result and return it to be used instead. `onNext` originally had the `NextMessage` argument which already has the `FormattedExecutionResult`, and `onError` originally had the `ErrorMessage` argument which already has the `GraphQLFormattedError`, and they both also returned `FormattedExecutionResult` and `GraphQLFormattedError` respectivelly - meaning, if the user serialised the results - the serialisation would happen **twice**.

+
+#### `onSubscribe`
+
+```diff
+import { ServerOptions, SubscribePayload } from 'graphql-ws';
+
+const opts: ServerOptions = {
+- onSubscribe(ctx, message) {
+-   const messageId = message.id;

+- },
++ onSubscribe(ctx, id, payload) {
++   const messageId = id;
++   const messagePayload: SubscribePayload = payload;
++ },
+};
+```
+
+#### `onOperation`
+
+The `SubscribeMessage.payload` is not useful here at all, the `payload` has been parsed to ready-to-use graphql execution args and should be used instead.
+
+```diff
+import { ExecutionArgs } from 'graphql';
+import { ServerOptions, SubscribePayload } from 'graphql-ws';
+
+const opts: ServerOptions = {
+- onOperation(ctx, message) {

+- },
++ onOperation(ctx, id, args) {
++   const messageId = id;
++   const executionArgs: ExecutionArgs = args;
++ },
+};
+```
+
+#### `onError`
+
+The `ErrorMessage.payload` (`GraphQLFormattedError[]`) is not useful here at all, the user has access to `GraphQLError[]` that are true instances of the error containing object references to `originalError`s and other properties. The user can always convert and return `GraphQLFormattedError[]` by using the `.toJSON()` method.
+
+```diff
+import { GraphQLError, GraphQLFormattedError } from 'graphql';

++ },

+The `NextMessage.payload` (`FormattedExecutionResult`) is not useful here at all, the user has access to `ExecutionResult` that contains actual object references to error instances.

+Errors thrown from subscription iterables will be caught and reported through the `ErrorMessage`
+
+Compared to the behaviour before, which terminated the whole WebSocket connection - those errors are now gracefully reported and terminate only the specific subscription that threw the error.
+
+There's been [an editorial change in the GraphQL Spec suggesting this being the correct approach](https://github.com/graphql/graphql-spec/pull/1099).
+
+Also, if you'd like to get involved and ideally drop your opinion about whether iterable errors should be reported as errors or `ExecutionResult`s with `errors` field set, [please read more here](https://github.com/graphql/graphql-spec/pull/1127).
+
+### Migrating from v5 to v6
+
+If you had used the suggested "ws server usage with custom subscribe method that gracefully handles thrown errors" recipe, you can simply remove it since this behaviour is now baked in.
+
+```diff
+import { subscribe } from 'graphql';
+import { useServer } from 'graphql-ws/use/ws';
+import { WebSocketServer } from 'ws'; // yarn add ws
+
+const wsServer = new WebSocketServer({
