dear all,

i'm unable to find the elasticsearch server vs client sdk version comparability matrix and as well as version upgrade comparability path matrix

have found only for go lang [Installation | Go](https://www.elastic.co/docs/reference/elasticsearch/clients/go/installation)  
still it is also very minimum info only.

is there any such page for Client SDK version as like this ?[Support Matrix | Elastic](https://www.elastic.co/support/matrix#matrix_browsers)

Hi @kanamani92 !

[Clients page](https://www.elastic.co/docs/reference/elasticsearch-clients/) is the root page for the different Elasticsearch clients. Each client has a compatibility matrix (for example, [Java server compatibility](https://www.elastic.co/docs/reference/elasticsearch/clients/java#_elasticsearch_server_compatibility_policy)).

In general, you can expect the following:

> client is forward compatible; meaning that the client supports 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.

Hope this helps!
