Hi @myhrman,
all the fixes should be in this release apart from things involving the AudioProcessorGraph or hosting multi-bus plug-ins. Also, we haven’t touched the API in this release - but we will rename a few things going forward to avoid confusion. This will also get rid of the macros being using in AudioProcessor.cpp.
In addition, this release offers more control for VST-2 plug-ins if you use the setBusArrangement API. See examples/PluginSamples/GainPlugin for this. For example, if JUCE detects that you are using the setBusArrangement API, then the layout set in the constructor of your plug-in will be the default VST-2 plug-in layout. You can also indirectly specify the maximum number of supported channels in the setPreferredBusArrangement callback. See the example for more details.
