 ### Added
 
 - A new sub-command `villas-relay` implements a client-to-client WebSocket relay.

+- New node-types: infiniband, rtp, uldaq
+- VILLASnode got a similarily named Python package: `villas.node`.
+  It can be used to interact or start an VILLASnode instance. 
+
+### Changed

+  Most node configs are now separated into `in` and `out` sections.
+- We ported major parts of the VILLASnode code base to C++.
+- Some of the common utilities have been moved to a new repo.
+  VILLAScommon is used also by other related VILLAS components.
+  Please make sure to checkout / update the `common/` Git sub-module.
