## Compatibility
The Elasticsearch client is compatible with currently maintained JS versions.
Language clients are forward compatible; meaning that clients support
communicating with greater or equal minor versions of Elasticsearch without
breaking. It does not mean that the client automatically supports new features
of newer Elasticsearch versions; it is only possible after a release of a new
client version. For example, a 8.12 client version won't automatically support
the new features of the 8.13 version of Elasticsearch, the 8.13 client version
is required for that. Elasticsearch language clients are only backwards
compatible with default distributions and without guarantees made.

| main | main | |
| 8.x | 8.x | 8.x |

Elasticsearch language clients are only backwards compatible with default distributions and without guarantees made.
Language clients are forward compatible; meaning that clients support
communicating with greater or equal minor versions of {es} without breaking. It
does not mean that the client automatically supports new features of newer {es}
versions; it is only possible after a release of a new client version. For
example, a 8.12 client version won't automatically support the new features of
the 8.13 version of {es}, the 8.13 client version is required for that.
