-### Node.js support
-
-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)    |       
-| `10.x`          | `Apri 2021`      | `7.12` (mid 2021)      |

 ### Compatibility
 
+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.
