[0.7.1] - 2019-01-23

Fixed

• Removed most of the static storage variables from libvillas and libvillas-common which caused crashes with DPsim.
• Fixed compilation with Ubuntu 16.04 and GCC 7.2.
• Fixed broken shmem node-type since addition of signal defintions.

Changed

• Node-types can now handle more than a single file-descriptor for poll() multiplexing.
• Enable network emulation sub-system also for other node-types than socket. The rtp node-type will support it now as well.
• Improve readabilty of log output

Added

• Initial rate-limiting support for rtp node-type based on Additive Increase / Multiplicative Decrease (AIMD) and RTCP.

[0.7.0] - 2019-01-13

Added

• A new sub-command villas-relay implements a client-to-client WebSocket relay. It can be used as a proxy for nodes which sit behind a NAT firewall.
• 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

• The syntax of the configuration file has changed in several places. 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.
• We build and test VILLASnode now with Fedora 29.

Fixed

• All unit tests are running again. Most of the integration tests run again as well.
• We added support for the ARM architecture.

[0.6.4] - 2018-07-18

Added

• New client User Code Model (UCM) for OPAL-RT HYPERSIM digital real-time simulator
• New node-types:
  • infiniband is using the Infiniband IBverbs and RDMA CM APIs for a low latency interface between simualation nodes.
  • comedi adds support for ADC and DAC cards supported by the Comedi Linux control and measurment device interface.
• All header files can now be imported into C++ code. Missing extern "C" declarations have been added.

Changed

• The VILLASnode project is now built with CMake. The old Makefile have been removed.
• The VILLASnode project will be gradually ported to C++. The tools (/tools/), executables (/src/) and plugins (/plugins/) have already been convert to C++ code.

[0.6.3] - 2018-06-04

Added

• The csv IO format has been splitted into a similar tsv IO format which uses tabulators instead of commas.
• The struct queue_signalled supports now synchronization under Mac OS X.
• A new poll setting allows the user to enable/disable the usage of poll(2) when reading from multiple source nodes.

Changed

• Started splitting the node configuration into a send and receive side. This changes will be soon also reflected in a changed configuration file syntax.
• Docker images are now based on Fedora 28.

Fixed

• We now correctly determine with terminal size when executed in GDB or by the CI runner.

[0.6.2] - 2018-05-14

Added

• A Docker application image can now be build in a single step using make docker.

Changed

• The IO format names have changed. They now use dots (raw.flt32) instead of hyphens (raw-flt32) in their name. Please update your configuration files accordingly.
• The configuration of many node-types is now splitted into seperate in and out sections. Please update your configuration files accordingly.
