-### Node.js support
-
-NOTE: The minimum supported version of Node.js is `v12`.
-
-The client versioning follows the Elastic Stack versioning, this means that
-major, minor, and patch releases are done following a precise schedule that
-often does not coincide with the [Node.js release](https://nodejs.org/en/about/releases/) times.
-
-To avoid support insecure and unsupported versions of Node.js, the
-client **will drop the support of EOL versions of Node.js between minor releases**.
-Typically, as soon as a Node.js version goes into EOL, the client will continue
-to support that version for at least another minor release. If you are using the client
-with a version of Node.js that will be unsupported soon, you will see a warning
-in your logs (the client will start logging the warning with two minors in advance).
-
-Unless you are **always** using a supported version of Node.js, 
-we recommend defining the client dependency in your
-`package.json` with the `~` instead of `^`. In this way, you will lock the
-dependency on the minor release and not the major. (for example, `~7.10.0` instead
-of `^7.10.0`).
-
-| Node.js Version | Node.js EOL date | End of support         |
-| --------------- |------------------| ---------------------- |
-| `8.x`           | `December 2019`  | `7.11` (early 2021)    |
-| `10.x`          | `April 2021`      | `7.12` (mid 2021)     |
-| `12.x`          | `April 2022`      | `8.2` (early 2022)     |
-
 ### Compatibility
 
-Language clients are forward compatible; meaning that clients support communicating with greater or equal minor versions of Elasticsearch.
-Elasticsearch language clients are only backwards compatible with default distributions and without guarantees made.
+The minimum supported version of Node.js is `v8`.
+
+The library is compatible with all Elasticsearch versions since 5.x, and you should use the same major version of the Elasticsearch instance that you are using.

 ## Quick start
 
+First of all, require the client and initialize it:
+```js
+const { Client } = require('@elastic/elasticsearch')
+const client = new Client({ node: 'http://localhost:9200' })
+```
+
+You can use both the callback-style API and the promise-style API, both behave the same way.
+```js
+// promise API
+const result = await client.search({
+  index: 'my-index',
+  body: {
+    query: {
+      match: { hello: 'world' }
+    }
+  }
+})
+
+// callback API
+client.search({
+  index: 'my-index',
+  body: {
+    query: {
+      match: { hello: 'world' }
+    }
+  }
+}, (err, result) => {
+  if (err) console.log(err)
+})
+```
+The returned value of **every** API call is formed as follows:
+```ts
+{
+  body: object | boolean
+  statusCode: number
+  headers: object
+  warnings: [string]
+  meta: object

-
-

-
-This class is responsible for keeping in memory all the {es} Connection that you

-==== Migrate to v8
-
-The Node.js client can be configured to emit an HTTP header
-``Accept: application/vnd.elasticsearch+json; compatible-with=7``
-which signals to Elasticsearch that the client is requesting
-``7.x`` version of request and response bodies. This allows for
-upgrading from 7.x to 8.x version of Elasticsearch without upgrading
-everything at once. Elasticsearch should be upgraded first after
-the compatibility header is configured and clients should be upgraded
-second.
-To enable to setting, configure the environment variable
-``ELASTIC_CLIENT_APIVERSIONING`` to ``true``.

+== Authentication
+
+This document contains code snippets to show you how to connect to various {es} 
+providers.
+
+
+=== Elastic Cloud
+
+If you are using https://www.elastic.co/cloud[Elastic Cloud], the client offers 
+an easy way to connect to it via the `cloud` option. You must pass the Cloud ID 
+that you can find in the cloud console, then your username and password inside 
+the `auth` option.
+
+NOTE: When connecting to Elastic Cloud, the client will automatically enable 
+both request and response compression by default, since it yields significant 
+throughput improvements. Moreover, the client will also set the ssl option 
+`secureProtocol` to `TLSv1_2_method` unless specified otherwise. You can still 
+override this option by configuring them.
+
+IMPORTANT: Do not enable sniffing when using Elastic Cloud, since the nodes are 
+behind a load balancer, Elastic Cloud will take care of everything for you.
+Take a look https://www.elastic.co/blog/elasticsearch-sniffing-best-practices-what-when-why-how[here]
+to know more.
+
+[source,js]
+----
+const { Client } = require('@elastic/elasticsearch')
+const client = new Client({
+  cloud: {
+    id: 'name:bG9jYWxob3N0JGFiY2QkZWZnaA==',
+  },
+  auth: {
+    username: 'elastic',
+    password: 'changeme'
+  }
+})
+----
+
+
+=== Basic authentication
+
+You can provide your credentials by passing the `username` and `password` 
+parameters via the `auth` option.
+
+NOTE: If you provide both basic authentication credentials and the Api Key configuration, the Api Key will take precedence.
+
+[source,js]
+----
+const { Client } = require('@elastic/elasticsearch')
+const client = new Client({
+  node: 'https://localhost:9200',
+  auth: {
+    username: 'elastic',
+    password: 'changeme'
+  }
+})
+----
+
+
+Otherwise, you can provide your credentials in the node(s) URL.
+
+[source,js]
+----
+const { Client } = require('@elastic/elasticsearch')
+const client = new Client({
+  node: 'https://username:password@localhost:9200'
+})
+----
+
+
+=== ApiKey authentication
+
+You can use the 
+https://www.elastic.co/guide/en/elasticsearch/reference/7.x/security-api-create-api-key.html[ApiKey] 
+authentication by passing the `apiKey` parameter via the `auth` option. The 
+`apiKey` parameter can be either a base64 encoded string or an object with the 
+values that you can obtain from the 
+https://www.elastic.co/guide/en/elasticsearch/reference/7.x/security-api-create-api-key.html[create api key endpoint].
+
+NOTE: If you provide both basic authentication credentials and the Api Key configuration, the Api Key will take precedence.
+
+[source,js]
+----
+const { Client } = require('@elastic/elasticsearch')
+const client = new Client({
+  node: 'https://localhost:9200',
+  auth: {

+      id: 'foo',
+      api_key: 'bar'
+    }
+  }
+})
+----
+
+
+=== SSL configuration
+
+Without any additional configuration you can specify `https://` node urls, and 
+the certificates used to sign these requests will be verified. To turn off certificate verification, you must specify an `ssl` object in the top level config and set `rejectUnauthorized: false`. The default `ssl` values are the same that Node.js's https://nodejs.org/api/tls.html#tls_tls_connect_options_callback[`tls.connect()`] 
+uses.

+== Breaking changes coming from the old client
+
+If you were already using the previous version of this client – the one you used 
+to install with `npm install elasticsearch` – you will encounter some breaking 
+changes.
+
+
+=== Don’t panic!
+
+Every breaking change was carefully weighed, and each is justified. Furthermore, 
+the new codebase has been rewritten with modern JavaScript and has been 
+carefully designed to be easy to maintain.
+
+
+=== Breaking changes
+
+*  Minimum supported version of Node.js is `v8`.
+
+* Everything has been rewritten using ES6 classes to help users extend the 
+defaults more easily.
+
+* There is no longer an integrated logger. The client now is an event emitter 
+that emits the following events: `request`, `response`, and `error`.
+
+* The code is no longer shipped with all the versions of the API, but only that 
+of the package’s major version. This means that if you are using {es} `v6`, you 
+are required to install `@elastic/elasticsearch@6`, and so on.
+
+* The internals are completely different, so if you used to tweak them a lot, 
+you will need to refactor your code. The public API should be almost the same.
+
+* There is no longer browser support, for that will be distributed via another 
+module: `@elastic/elasticsearch-browser`. This module is intended for Node.js 
+only.
+
+* The returned value of an API call will no longer be the `body`, `statusCode`, 
+and `headers` for callbacks, and only the `body` for promises. The new returned 
+value will be a unique object containing the `body`, `statusCode`, `headers`, 
+`warnings`, and `meta`, for both callback and promises.
+
+
+[source,js]
+----
+// before
+const body = await client.search({
+  index: 'my-index',
+  body: { foo: 'bar' }
+})
+
+client.search({
+  index: 'my-index',
+  body: { foo: 'bar' }
+}, (err, body, statusCode, headers) => {
+  if (err) console.log(err)
+})
+
+// after
+const { body, statusCode, headers, warnings } = await client.search({
+  index: 'my-index',
+  body: { foo: 'bar' }
+})
+
+client.search({
+  index: 'my-index',
+  body: { foo: 'bar' }
+}, (err, { body, statusCode, headers, warnings }) => {
+  if (err) console.log(err)
+})
+----
+
+
+* Errors: there is no longer a custom error class for every HTTP status code 
+(such as `BadRequest` or `NotFound`). There is instead a single `ResponseError`. 
+Every error class has been renamed, and now each is suffixed with `Error` at the 
+end.
+
+* Removed errors: `RequestTypeError`, `Generic`, and all the status code 
+specific errors (such as `BadRequest` or `NotFound`).
+
+* Added errors: `ConfigurationError` (in case of bad configurations) and 
+`ResponseError` that contains all the data you may need to handle the specific 
+error, such as `statusCode`, `headers`, `body`, and `message`.
+
+
+* Renamed errors:
+
+** `RequestTimeout` (408 statusCode) => `TimeoutError`
+** `ConnectionFault` => `ConnectionError`
+** `NoConnections` => `NoLivingConnectionsError`
+** `Serialization` => `SerializationError`
+** `Serialization` => `DeserializationError`
+
+* You must specify the port number in the configuration. In the previous 
+version, you can specify the host and port in a variety of ways. With the new 
+client, there is only one way to do it, via the `node` parameter.
+
+* Certificates are verified by default, if you want to disable certificates verification, you should set the `rejectUnauthorized` option to `false` inside the `ssl` configuration:
+
+[source,js]
+----
+const { Client } = require('@elastic/elasticsearch')
+const client = new Client({
+  ssl: { rejectUnauthorized: false }
+})
+----
+
+* The `plugins` option has been removed. If you want to extend the client now, 
+you should use the `client.extend` API.
+
+[source,js]
+----
+// before
+const { Client } = require('elasticsearch')
+const client = new Client({ plugins: [...] })
+
+// after
+const { Client } = require('@elastic/elasticsearch')
+const client = new Client({ ... })
+client.extend(...)
+----
+
+* There is a clear distinction between the API related parameters and the client 
+related configurations. The parameters `ignore`, `headers`, `requestTimeout` and 
+`maxRetries` are no longer part of the API object and you need to specify them 
+in a second option object.
+
+[source,js]
+----
+// before
+const body = await client.search({
+  index: 'my-index',
+  body: { foo: 'bar' },
+  ignore: [404]
+})
+
+client.search({
+  index: 'my-index',
+  body: { foo: 'bar' },
+  ignore: [404]
+}, (err, body, statusCode, headers) => {
+  if (err) console.log(err)
+})
+
+// after
+const { body, statusCode, headers, warnings } = await client.search({
+  index: 'my-index',
+  body: { foo: 'bar' }
+}, {
+  ignore: [404]
+})
+
+client.search({
+  index: 'my-index',
+  body: { foo: 'bar' }
+}, {
+  ignore: [404]
+}, (err, { body, statusCode, headers, warnings }) => {
+  if (err) console.log(err)
+})
+----
+
+* The `transport.request` method no longer accepts the `query` key. Use the 
+`querystring` key instead (which can be a string or an object). You also 
+need to send a bulk-like request instead of the `body` key, use the `bulkBody` 
+key. In this method, the client specific parameters should be passed as a second 
+object.
+
+[source,js]
+----
+// before
+const body = await client.transport.request({
+  method: 'GET',
+  path: '/my-index/_search',
+  body: { foo: 'bar' },
+  query: { bar: 'baz' }
+  ignore: [404]
+})
+
+client.transport.request({
+  method: 'GET',
+  path: '/my-index/_search',
+  body: { foo: 'bar' },
+  query: { bar: 'baz' }
+  ignore: [404]
+}, (err, body, statusCode, headers) => {
+  if (err) console.log(err)
+})
+
+// after
+const { body, statusCode, headers, warnings } = await client.transport.request({
+  method: 'GET',
+  path: '/my-index/_search',
+  body: { foo: 'bar' },
+  querystring: { bar: 'baz' }

+  ignore: [404]
+})
+
+client.transport.request({
+  method: 'GET',
+  path: '/my-index/_search',
+  body: { foo: 'bar' },
+  querystring: { bar: 'baz' }
+}, {
+  ignore: [404]
+}, (err, { body, statusCode, headers, warnings }) => {
+  if (err) console.log(err)
+})
+----
+
+=== Talk is cheap. Show me the code.
+
+You can find a code snippet with the old client below followed by the same code 
+logic but with the new client.
+
+[source,js]
+----
+const { Client, errors } = require('elasticsearch')
+const client = new Client({
+  host: 'http://localhost:9200',
+  plugins: [utility]
+})
+
+async function run () {

+    console.log(body)
+  } catch (err) {

+      console.log('Bad request')
+    } else {
+      console.log(err)
+    }
+  }
+}
+
+function utility (Client, config, components) {
+  const ca = components.clientAction.factory
+  Client.prototype.utility = components.clientAction.namespaceFactory()
+  const utility = Client.prototype.utility.prototype
+
+  utility.index = ca({

+        }
+      }
+    ],
+    needBody: true,
+    method: 'POST'
+  })
+})
+----
+
+And now with the new client.
+
+[source,js]
+----
+const { Client, errors } = require('@elastic/elasticsearch')
+// NOTE: `host` has been renamed to `node`,
+//       and `plugins` is no longer supported

+    })
+    console.log(body)
+  } catch (err) {
+    // NOTE: we are checking the `statusCode` property

+      console.log('Bad request')
+    } else {
+      console.log(err)
+    }
+  }
+}
+
+// NOTE: we can still extend the client, but with  a different API.

-===== Export SniffingTransport https://github.com/elastic/elasticsearch-js/pull/1653[#1653]
+=====  Added multi search helper https://github.com/elastic/elasticsearch-js/pull/1186[#1186]
 
-Now the client exports the SniffingTransport class.
+If you are sending search request at a high rate, this helper might be useful for you.
+It will use the mutli search API under the hood to batch the requests and improve the overall performances of your application. +
+The `result` exposes a `documents` property as well, which allows you to access directly the hits sources.
+
+[source,js]
+----
+const { Client } = require('@elastic/elasticsearch')
+
+const client = new Client({ node: 'http://localhost:9200' })
+const m = client.helpers.msearch()
+
+// promise style API
+m.search(
+    { index: 'stackoverflow' },
+    { query: { match: { title: 'javascript' } } }
+  )
+  .then(result => console.log(result.body)) // or result.documents
+  .catch(err => console.error(err))
+
+// callback style API
+m.search(
+  { index: 'stackoverflow' },
+  { query: { match: { title: 'ruby' } } },
+  (err, result) => {
+    if (err) console.error(err)
+    console.log(result.body)) // or result.documents
+  }
+)
+----
+
+=====  Added timeout support in bulk and msearch helpers https://github.com/elastic/elasticsearch-js/pull/1206[#1206]
+
+If there is a slow producer, the bulk helper might send data with a very large period of time, and if the process crashes for any reason, the data would be lost.
+This pr introduces a `flushInterval` option in the bulk helper to avoid this issue. By default, the bulk helper will flush the data automatically every 30 seconds, unless the threshold has been reached before.
+
+[source,js]
+----
+const b = client.helpers.bulk({
+  flushInterval: 30000
+})
+----
+
+The same problem might happen with the multi search helper, where the user is not sending search requests fast enough. A `flushInterval` options has been added as well, with a default value of 500 milliseconds.
+
+[source,js]
+----
+const m = client.helpers.msearch({
+  flushInterval: 500
+})
+----
+
+==== Internals
+
+=====  Use filter_path for improving the search helpers performances https://github.com/elastic/elasticsearch-js/pull/1199[#1199]
+
+From now on, all he search helpers will use the `filter_path` option automatically when needed to retrieve only the hits source. This change will result in less netwprk traffic and improved deserialization performances.
+
+=====  Search helpers documents getter https://github.com/elastic/elasticsearch-js/pull/1186[#1186]
+
+Before this, the `documents` key that you can access in any search helper was computed as soon as we got the search result from Elasticsearch. With this change the `documents` key is now a getter, which makes this procees lazy, resulting in better performances and lower memory impact.
+
+
+=== 7.7.1
 
-[discrete]
 ==== Fixes
 
-[discrete]
-===== Cleanup abort listener https://github.com/elastic/elastic-transport-js/pull/42[transport/#42]
+===== Disable client Helpers in Node.js < 10 - https://github.com/elastic/elasticsearch-js/pull/1194[#1194]
 
-The legacy http client was not cleaning up the abort listener, which could cause a memory leak.
+The client helpers can't be used in Node.js < 10 because it needs a custom flag to be able to use them.
+Given that not every provider allows the user to specify cuatom Node.js flags, the Helpers has been disabled completely in Node.js < 10.
 
-[discrete]
-===== Improve undici performances https://github.com/elastic/elastic-transport-js/pull/41[transport/#41]
+===== Force lowercase in all headers - https://github.com/elastic/elasticsearch-js/pull/1187[#1187]
 
-Improve the stream body collection and keep alive timeout.
+Now all the user-provided headers names will be lowercased by default, so there will be no conflicts in case of the same header with different casing.

-[discrete]
-===== Drop old typescript definitions
+===== Introduced client helpers - https://github.com/elastic/elasticsearch-js/pull/1107[#1107]
 
-*Breaking: Yes* | *Migration effort: Medium*
+From now on, the client comes with an handy collection of helpers to give you a more comfortable experience with some APIs.
 
-The current TypeScript definitions will be removed from the client, and the new definitions, which contain request and response definitions as well will be shipped by default.
+CAUTION: The client helpers are experimental, and the API may change in the next minor releases.
 
-[discrete]
-===== Drop callback-style API
+The following helpers has been introduced:
 
-*Breaking: Yes* | *Migration effort: Large*
+- `client.helpers.bulk`
+- `client.helpers.search`
+- `client.helpers.scrollSearch`
+- `client.helpers.scrollDocuments`
+
+===== The `ConnectionPool.getConnection` now always returns a `Connection` - https://github.com/elastic/elasticsearch-js/pull/1127[#1127]
+
+What does this mean? It means that you will see less `NoLivingConnectionError`, which now can only be caused if you set a selector/filter too strict.
+For improving the debugging experience, the `NoLivingConnectionsError` error message has been updated.
+
+===== Abortable promises - https://github.com/elastic/elasticsearch-js/pull/1141[#1141]
+
+From now on, it will be possible to abort a request generated with the promise-styl API. If you abort a request generated from a promise, the promise will be rejected with a `RequestAbortedError`.
 
-Maintaining both API styles is not a problem per se, but it makes error handling more convoluted due to async stack traces.
-Moving to a full-promise API will solve this issue.

-The old abort API makes sense for callbacks but it's annoying to use with promises
-
-[source,js]
-----
-// callback-style api
-const request = client.search({ params }, { options }, (err, result) => {
- console.log(err) // RequestAbortedError
-})
-
-request.abort()
-
-// promise-style api
-const promise = client.search({ params }, { options })

+  .catch(console.log)
 
 promise.abort()

-Node v12 has added the standard https://nodejs.org/api/globals.html#globals_class_abortcontroller[`AbortController`] API which is designed to work well with both callbacks and promises.
-[source,js]
-----
-const ac = new AbortController()
-client.search({ params }, { signal: ac.signal })
-  .then(console.log)
-  .catch(console.log) // RequestAbortedError
+===== Major refactor of the Type Definitions - https://github.com/elastic/elasticsearch-js/pull/1119[#1119] https://github.com/elastic/elasticsearch-js/issues/1130[#1130] https://github.com/elastic/elasticsearch-js/pull/1132[#1132]
 
-ac.abort()
+Now every API makes better use of the generics and overloading, so you can (or not, by default request/response bodies are `Record<string, any>`) define the request/response bodies in the generics.
+[source,ts]
+----
+// request and response bodies are generics
+client.search(...)
+// response body is `SearchResponse` and request body is generic
+client.search<SearchResponse>(...)
+// request body is `SearchBody` and response body is `SearchResponse`
+client.search<SearchResponse, SearchBody>(...)
 ----
 
-[discrete]
-===== Remove the body key from the request
+This *should* not be a breaking change, as every generics defaults to `any`. It might happen to some users that the code breaks, but our test didn't detect any of it, probably because they were not robust enough. However, given the gigantic improvement in the developer experience, we have decided to release this change in the 7.x line.
 
-*Breaking: Yes* | *Migration effort: Small*
+==== Fixes
 
-Thanks to the new types we are developing now we know exactly where a parameter should go.
-The client API leaks HTTP-related notions in many places, and removing them would definitely improve the DX.
+===== The `ConnectionPool.update` method now cleans the `dead` list - https://github.com/elastic/elasticsearch-js/issues/1122[#1122] https://github.com/elastic/elasticsearch-js/pull/1127[#1127]
 
-This could be a rather big breaking change, so a double solution could be used during the 8.x lifecycle. (accepting body keys without them being wrapped in the body as well as the current solution).
+It can happen in a situation where we are updating the connections list and running sniff, leaving the `dead` list in a dirty state. Now the `ConnectionPool.update` cleans up the `dead` list every time, which makes way more sense given that all the new connections are alive.
 
-[source,js]
-----
-// from
-const response = await client.search({
-  index: 'test',
-  body: {
-    query: {
-      match_all: {}
-    }
-  }
-})
+===== `ConnectionPoolmarkDead` should ignore connections that no longer exists - https://github.com/elastic/elasticsearch-js/pull/1159[#1159]
 
-// to
-const response = await client.search({
-  index: 'test',
-  query: {
-    match_all: {}
-  }
-})
-----
+It might happen that markDead is called just after a pool update, and in such case, the clint was adding the dead list a node that no longer exists, causing unhandled exceptions later.
 
-[discrete]
-===== Migrate to new separate transport
+===== Do not retry a request if the body is a stream - https://github.com/elastic/elasticsearch-js/pull/1143[#1143]
 
-*Breaking: Yes* | *Migration effort: Small to none*
+The client should not retry if it's sending a stream body, because it should store in memory a copy of the stream to be able to send it again, but since it doesn't know in advance the size of the stream, it risks to take too much memory.
+Furthermore, copying everytime the stream is very an expensive operation.
 
-The separated transport has been rewritten in TypeScript and has already dropped the callback style API.
-Given that now is separated, most of the Elasticsearch specific concepts have been removed, and the client will likely need to extend parts of it for reintroducing them.
-If you weren't extending the internals of the client, this won't be a breaking change for you.
+===== Return an error if the request has been aborted - https://github.com/elastic/elasticsearch-js/pull/1141[#1141]
 
-[discrete]
-===== The returned value of API calls is the body and not the HTTP related keys
+Until now, aborting a request was blocking the HTTP request, but never calling the callback or resolving the promise to notify the user. This is a bug because it could lead to dangerous memory leaks. From now on if the user calls the `request.abort()` method, the callback style API will be called with a `RequestAbortedError`, the promise will be rejected with `RequestAbortedError` as well.
 
-*Breaking: Yes* | *Migration effort: Small*
+=== 7.6.1
 
-The client API leaks HTTP-related notions in many places, and removing them would definitely improve the DX.
-The client will expose a new request-specific option to still get the full response details.

-===== Use a weighted connection pool
+=== 7.6.0
 
-*Breaking: Yes* | *Migration effort: Small to none*
+Support for Elasticsearch `v7.6`.
 
-Move from the current cluster connection pool to a weight-based implementation.
-This new implementation offers better performances and runs less code in the background, the old connection pool can still be used.
-If you weren't extending the internals of the client, this won't be a breaking change for you.

-===== Migrate to the "undici" http client
+**Fixes:**
 
-*Breaking: Yes* | *Migration effort: Small to none*
+- Skip compression in case of empty string body - https://github.com/elastic/elasticsearch-js/pull/1080[#1080]

+- ClientOptions["cloud"] should have optional auth fields - https://github.com/elastic/elasticsearch-js/pull/1032[#1032]
 
-By default, the HTTP client will no longer be the default Node.js HTTP client, but https://github.com/nodejs/undici[undici] instead.
-Undici is a brand new HTTP client written from scratch, it offers vastly improved performances and has better support for promises.
-Furthermore, it offers comprehensive and predictable error handling. The old HTTP client can still be used.
-If you weren't extending the internals of the client, this won't be a breaking change for you.

-*Breaking: Yes* | *Migration effort: Medium*
+=== 7.5.0
 
-Currently, every path or query parameter could be expressed in both `snake_case` and `camelCase`. Internally the client will convert everything to `snake_case`. 
-This was done in an effort to reduce the friction of migrating from the legacy to the new client, but now it no longer makes sense.
-If you are already using `snake_case` keys, this won't be a breaking change for you.
