+- Updated for the changes in yabridge 3.0. Yabridgectl now allows you to set up
+  yabridge for VST3 plugins. Since `libyabridge.so` got renamed to
+  `libyabridge-vst2.so` in this version, it's advised to carefully remove the
+  old `libyabridge.so` and `yabridgectl` files before upgrading to avoid
+  confusing situations.
