-### Compatibility
+### Node.js support
 
-The minimum supported version of Node.js is `v8`.
+NOTE: The minimum supported version of Node.js is `v10`.
+
+The client versioning follows the Elastc 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)    |

 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.

+* `ConnectionPool` class
+* `Connection` class
+* `Serializer` class
+

+==== `Transport`
+
+This class is responsible for performing the request to {es} and handling

+following methods:
+
+* `serialize(object: any): string;` serializes request objects.
+* `deserialize(json: string): any;` deserializes response strings.

-== 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.

-
-=== 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.

-=== 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.

+
+When using a body that is a stream to client.search(), and calling req.abort(), the callback is called twice.
+Once for the RequestAbortedError, as expected, and once for a "premature close" error from end-of-stream, used by pump, used by the client.
+This issue has now been fixed.
+
+[discrete]
+=== 7.10.0
+
+[discrete]
+==== Features
+
+[discrete]
+===== Support for Elasticsearch `v7.10`.
+
+You can find all the API changes https://www.elastic.co/guide/en/elasticsearch/reference/7.10/release-notes-7.10.0.html[here].
+
+[discrete]
+=====  Added proxy support https://github.com/elastic/elasticsearch-js/pull/1260[#1260]
+
+If you need to pass through an http(s) proxy for connecting to Elasticsearch, the client offers
+out of the box a handy configuration for helping you with it. Under the hood it
+uses the https://github.com/delvedor/hpagent[`hpagent`] module.

+==== Fixes
+
+[discrete]
+===== Scroll search should clear the scroll at the end https://github.com/elastic/elasticsearch-js/pull/1331[#1331]
+
+From now on the scroll search helper will automatically close the scroll on Elasticsearch,
+by doing so, Elasticsearch will free resources faster.
+
+[discrete]
+===== Handle connectivity issues while reading the body https://github.com/elastic/elasticsearch-js/pull/1343[#1343]
+
+It might happen that the underlying socket stops working due to an external cause while reading the body.
+This could lead to an unwanted `DeserialzationError`. From now, this will be handled as a generic `ConnectionError`.
+
+[discrete]
+==== Warnings
+
+[discrete]
+===== Add warning log about nodejs version support https://github.com/elastic/elasticsearch-js/pull/1349[#1349]
+
+`7.11` will be the last version of the client that will support Node.js v8, while `7.12` will be
+the last one that supports Node.js v10. If you are eusing this versions you will see a 
+`DeprecationWaring` in your logs. We strongly recommend to upgrade to newer versions of Node.js
+as usng an EOL version will expose you to securty risks.
+
+Please refer to https://ela.st/nodejs-support[ela.st/nodejs-support] for additional information.
+
+[discrete]
+=== 7.9.1
+
+[discrete]
+==== Fixes
+
+[discrete]
+===== Improve child performances https://github.com/elastic/elasticsearch-js/pull/1314[#1314]
+
+The client code has been refactored to speed up the performances of the child method.
+Before this pr, creating many children per second would have caused a high memory consumption and a spike in CPU usage.
+This pr changes the way the client is created by refactoring the code generation, now the clients methods are no longer added to the instance with a for loop but via prototypal inheritance. Thus, the overall performances are way better, now creating a child is ~5 times faster, and it consumes ~70% less memory.
+
+This change should not cause any breaking change unless you were mocking the client methods. In such case you should refactor it, or use https://github.com/elastic/elasticsearch-js-mock[elasticsearch-js-mock].
+
+Finally, this change should also fix once and of all the bundlers support.
+
+[discrete]
+===== Throw all errors asynchronously https://github.com/elastic/elasticsearch-js/pull/1295[#1295]
+
+Some validation errors were thrown synchronously, causing the callback to be called in th same tick.
+This issue is known as _"The release fo Zalgo"_ (see https://blog.izs.me/2013/08/designing-apis-for-asynchrony[here]).
+
+[discrete]
+===== Fix `maxRetries` request option handling https://github.com/elastic/elasticsearch-js/pull/1296[#1296]
+
+The `maxRetries` parameter can be configured on a per requets basis, if set to zero it was defaulting to the client default. Now the client is honoring the request specific configuration.
+
+[discrete]
+===== Fix RequestOptions.body type to include null https://github.com/elastic/elasticsearch-js/pull/1300[#1300]
+
+The Connection requets option types were not accepting `null` as valid value.
+
+[discrete]
+===== Fixed `size` and `maxRetries` parameters in helpers https://github.com/elastic/elasticsearch-js/pull/1284[#1284]
+
+The `size` parameter was being passed too the scroll request, which was causing an error.
+`maxRetries` setted to 0 was resulting in no request at all.
+
+[discrete]
+=== 7.9.0

+[discrete]
+==== Features

+===== Add ability to disable the http agent https://github.com/elastic/elasticsearch-js/pull/1251[#1251]

+
+[source,js]

+const client = new Client({
+  node: 'http://localhost:9200'.
+  agent: false
+})
+----
+
+[discrete]
+===== Add support for a global context option https://github.com/elastic/elasticsearch-js/pull/1256[#1256]
+
+Before this, you could set a `context` option in each request, but there was no way of setting it globally.
+Now you can by configuring the `context` object in the global configuration, that will be merged with the local one.
+
+[source,js]

+===== Fixed transport.request querystring type https://github.com/elastic/elasticsearch-js/pull/1240[#1240]
+
+Only `Record<string, any>` was allowed. Now `string` is allowed as well.
+
+[discrete]
+===== Fixed type definitions https://github.com/elastic/elasticsearch-js/pull/1263[#1263]
+
+* The `transport.request` defintion was incorrect, it was returning a `Promise<T>` instead of `TransportRequestPromise<T>`.
+* The `refresh` parameter of most APIs was declared as `'true' | 'false' | 'wait_for'`, which was clunky. Now is `'wait_for' | boolean`.
+
+[discrete]
+===== Generate response type as boolean if the request is HEAD only https://github.com/elastic/elasticsearch-js/pull/1275[#1275]
+
+All HEAD request will have the body casted to a boolean value, `true` in case of a 200 response, `false` in case of
+a 404 response. The type definitions were not reflecting this behavior.
+
+[source,ts]
+----
+import { Client } from '@elastic/elasticsearch'
+const client = new Client({
+  node: 'http://localhost:9200'
+})
+
+const { body } = await client.exist({ index: 'my-index', id: 'my-id' })
+console.log(body) // either `true` or `false`

+==== Internals
+
+[discrete]
+===== Updated default http agent configuration https://github.com/elastic/elasticsearch-js/pull/1242[#1242]
+
+Added the scheduling: 'lifo' option to the default HTTP agent configuration to avoid maximizing the open sockets
+against Elasticsearch and lowering the risk of encountering socket timeouts.
+This feature is only available from Node v14.5+, but it should be backported to v10 and v12. (https://github.com/nodejs/node/pull/33278[nodejs/node#33278])
+
+[discrete]
+===== Improve child API https://github.com/elastic/elasticsearch-js/pull/1245[#1245]
+
+This pr introduce two changes which should not impact the surface API:
+
+* Refactored the `client.child` API to allocate fewer objects, this change improves memory consumption over time
+and improves the child creation performances by ~12%.
+* The client no longer inherits from the EventEmitter class, but instead has an internal event emitter and exposes
+only the API useful for the users, namely `emit, `on`, `once`, and `off`. The type definitions have been updated accordingly.

 =====  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.

 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.

 ===== 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]
 
 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.
 
+[discrete]
 ===== `ConnectionPoolmarkDead` should ignore connections that no longer exists - https://github.com/elastic/elasticsearch-js/pull/1159[#1159]
 
 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]
 ===== Do not retry a request if the body is a stream - https://github.com/elastic/elasticsearch-js/pull/1143[#1143]
 
 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.
 
+[discrete]
 ===== Return an error if the request has been aborted - https://github.com/elastic/elasticsearch-js/pull/1141[#1141]
 
 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.

-If you need to customize the client behavior heavily, you are in the right 
-place! The client allows you to customize the following internals:
-
-* `Transport` class
-* `ConnectionPool` class
-* `Connection` class
-* `Serializer` class
-
-
-=== `Transport`
-
-This class is responsible for performing the request to {es} and handling 
-errors, it also handles the sniffing.
-
-[source,js]
-----
-const { Client, Transport } = require('@elastic/elasticsearch')
-
-class MyTransport extends Transport {
-  request (params, options, callback) {
-    // your code
-  }
-}
-
-const client = new Client({
-    Transport: MyTransport
-})
-----
-
-Sometimes you need to inject a small snippet of your code and then continue to 
-use the usual client code. In such cases, call `super.method`:

-    // your code
-    return super.request(params, options, callback)
-  }
-}
-----
-
-
-=== `ConnectionPool`
-
-This class is responsible for keeping in memory all the {es} Connection that we 
-are using. There is a single Connection for every node. The connection pool 
-handles the resurrection strategies and the updates of the pool.
-
-[source,js]
-----
-const { Client, ConnectionPool } = require('@elastic/elasticsearch')

-class MyConnectionPool extends ConnectionPool {
-  markAlive (connection) {
-    // your code
-    super.markAlive(connection)
-  }
-}
-
-const client = new Client({
-    ConnectionPool: MyConnectionPool
-})
-----
-
-
-=== `Connection`
-
-This class represents a single node, it holds every information we have on the 
-node, such as roles, id, URL, custom headers and so on. The actual HTTP request 
-is performed here, this means that if you want to swap the default HTTP client 
-(Node.js core), you should override the `request` method of this class.

-}
-
-const client = new Client({
-  Connection: MyConnection
-})
-----
-
-
-=== `Serializer`
-
-This class is responsible for the serialization of every request, it offers the 
-following methods:
-
-* `serialize(object: any): string;` serializes request objects.
-* `deserialize(json: string): any;` deserializes response strings.
-* `ndserialize(array: any[]): string;` serializes bulk request objects.

+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

+# Elasticsearch proxy example
+
+This folder contains an example of how to build a lightweight proxy
+between your frontend code and Elasticsearch if you don't
+have a more sophisticated backend in place yet.
+
+> **IMPORTANT:** This is not a production ready code and it is only for demonstration purposes,
+> we make no guarantees on it's security and stability.
+
+This project is designed to be deployed on [Vercel](https://vercel.com/), a cloud platform
+for static sites and Serverless Functions. You can use other functions providers,
+such as [Google Cloud functions](https://cloud.google.com/functions).
+
+## Project structure
+
+The project comes with four endpoints:
+
+- `/api/search`: runs a search, requires `'read'` permission
+- `/api/autocomplete`: runs an autocomplete suggestion, requires `'read'` permission
+- `/api/index`:  indexes or updates a document, requires `'write'` permission
+- `/api/delete`: deletes a document, requires `'write'` permission
+
+Inside `utils/authorize.js` you can find the authorization logic for the endpoints.
+In each endpoint you should configure the `INDEX` variable.
+
+## How to use
+
+Create an account on Vercel, then create a deployment on Elastic Cloud. If you
+don't have an account on Elastic Cloud, you can create one with a free 14-day trial
+of the [Elasticsearch Service](https://www.elastic.co/elasticsearch/service).
+
+### Configure Elasticsearch
+
+Once you have created a deployment on Elastic Cloud copy the generated Cloud Id and the credentials.
+Then open `utils/prepare-elasticsearch.js` and fill your credentials. The script generates
+an [Api Key](https://www.elastic.co/guide/en/elasticsearch/reference/current/security-api-create-api-key.html)
+that you can use for authenticating your request. Based on the configuration of the Api Key, you will be able
+to perform different operation on the specified indices or index pattern.
+
+### Configure Vercel
+
+Install the [Vercel CLI](https://vercel.com/docs/cli) to bootstrap the project,
+or read the [quickstart](https://vercel.com/docs) documentation.
+
+If you are using the CLI, bootstrap the project by running `vercel`. Test the project locally
+with `vercel dev`, and deploy it with `vercel deploy`.
+Configure the `ELASTIC_CLOUD_ID` [environment varible](https://vercel.com/docs/environment-variables) as well.
+The Api Key is passed from the frontend app via a `Authorization` header as `Bearer` token and is
+used to authorize the API calls to the endpoints as well.
+Additional configuration, such as CORS, can be added to [`vercel.json`](https://vercel.com/docs/configuration).
+
+## Authentication
+
+If you are using Elasticsearch only for search purposes, such as a search box, you can create
+an Api Key with `read` permissions and store it in your frontend app. Then you can send it
+via `Authorization` header to the proxy and run your searches.
+
+If you need to ingest data as well, it's more secure to have a strong authentication in your application.
+For such cases, use an external authentication service, such as [Auth0](https://auth0.com/)
+or [Magic Link](https://magic.link/). Then create a different Api Key with `read` and `write`
+permissions for authenticated users, that will not be stored in the frontend app.
