> When upgrading OpenWebRX, please make sure that you also upgrade *csdr*, and install the new dependency, *ncat*! **News (2017-04-04)**
- *ncat* has been replaced with a custom implementation called *nmux* due to a bug that caused regular crashes on some machines. The *nmux* tool is part of the *csdr* package.
