Thanks. 
I did the update, and I did a test using the dsp-file (an example from the Faust IDE with some added declarations on top) below:

I made a simple GUI with MIDI keyboard from the dsp file in the updated XUiDesigner, and then turned it into a Windows LV2 on the Command Line. A test with the Windows LV2 plugin in Reaper on my Windows laptop showed that it's still possible to generate hanging notes, but to do so I had to move the mouse extremely fast over de plugin's GUI keyboard in Reaper.
However in Reaper and Carla on my Windows laptop strange things happen with the created Windows LV2 plugin. The GUI is OK now, but notes are played when I hover above the plugin GUI keyboard with the mouse even without clicking, and after a while no more sounds are played.
