Release 0.3.0 is beta version. It covers almost all functions of Jack API, version 0.109.2. Currently unsupported functions and features are: -- jack_set_error_function (as it might by called by any native thread) -- port connect callback (due to bug in Jack 0.109.2) -- jack_client_create_thread (may be added after the "new thread model" is finally implemented in future versions of jackd/jackdmp) -- all functions and features deprecated in 0.109.2 List of planned additions/features: -- basic infrastructure for native "slaves" that would efficiently do the hard work for Java application (such as copying samples, resampling, applying gain, FFT etc.) -- JavaSound SPI classes
