+**Released:** 29th January 2025.

+* Open-source release -- Audio Orchestrator can now be built from our public [GitHub repository](https://github.com/bbc/audio-orchestrator).
+* The application name has been changed to "Audio Orchestrator", default exports are now prefixed with `audio-orchestrator`, and the log files are now in an "Audio Orchestrator" folder.
+* If multiple network interfaces are present, the preview server preferably picks one with an IPv4 address beginning with `192.` -- this may help in some corporate environments or when VPNs are used.
