# Qt Remote Objects Protocol Versioning

Qt Remote Objects uses an internal protocol to pass data between processes and/or devices. The same protocol version needs to be used by all parties: if there is a mismatch, the connecting node will output a warning and the host node will not send any data.

Currently released versions:

Protocol Version | Qt Version
--- | ---
<1.2 | Used during QtRO's tech preview phase.
1.2 | 5.12.0
1.3 | 5.12.4
