    - update to 2.0.4:
      This release adjusts the data rate limit imposed on MIDI through macOS IAC
      bus to avoid losing data (this is a macOS limitation, not a PortMidi
      limitation). Apparently, the limit was significantly dropped somewhere around
      macOS 12. This release is tested on Apple M2 in addition to Linux, Win32, and
      macOS Intel. It also includes a working but not complete port to Haiku.
