+- The way yabridge communicates between its plugin and the Wine host process has
+  been completely revamped. This was necessary to allow yabridge to handle
+  nested or mutually recursive function calls. What this boils down to is that
+  yabridge became even faster, more responsive, and can now handle a few edge
+  case scenarios that previously required workarounds. This means that yabridge
+  will now work out of the box with _REAPER_ and _Renoise_ and the
+  `hack_reaper_update_display` workaround for is no longer needed. I have been
+  testing this extensively to make sure that the change does not introduce any
+  regressions, but please let me know if this does break anything for you.
