+## Compatibility
+
+The Elasticsearch client is compatible with currently maintained PHP 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.
