 The language clients are forward compatible; meaning that the clients support communicating with greater or equal minor versions of {{es}} without breaking. It does not mean that the clients automatically support 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. {{es}} language clients are only backwards compatible with default distributions and without guarantees made.
