Hi All, A new build of JAudioLibs is now available for download, including improvements to the JNAJack Java bindings for JACK. Primarily this adds support for client and port registration callbacks, port connection callbacks, graph reorder callbacks and querying port connections. A huge thank you to Chuck Ritola for providing the bulk of this code.
