-=== Compatibility
-
-The `main` branch targets the next major release (8.0), the `7.x` branch targets
-the next minor release. Support is still incomplete as the API code is generated
-from the {es} Specification that is also still a work in progress.
-
-The {es} Java client is forward compatible; meaning that the client supports
-communicating with greater or equal minor versions of {es}. {es} language
-clients are only backwards compatible with default distributions and without
-guarantees made.
