    • now supporting up to 16 buses per track (main bus and 15 auxiliary buses).
    • track send panels allow choosing source, destination buses.
    • bus support for VST/AU/ReWire, JS (to use in JS, set ext_midi_bus=1 in @init, then midi_bus is used for bus indices).
  • API:
    • many new functions for FX presets, open/close UI, bypass, sends/receives, tempo.
    • many new functions for control surface support, scroll/zoom, track visibility, mixer scrolling.
    • access media item text notes via GetSetMediaItemInfo().
    • register OSC clients for 2-way communication.
    • GetSetObjectState() locking improvements for less audio interruption.
  • Freeze:
    • better subsample alignment of frozen items.
    • by default only the media items plus FX tail length setting are rendered, with options for other behavior.
    • fixed possible undo corruption of freeze states after reordering tracks.
    • fixed warning when unfreezing after editing frozen track.
    • freezing tracks clears track polarity, unfreezing restores.
  • OS X:
    • fixed focus-related issues when setting default text selections.
    • fullscreen mode auto-hides menu, hides dock on 10.6+ (pref to auto-hide dock in prefs/general/advanced).
    • possible stability improvements in certain instances (IsWindow() improvements).
    • compatibility fixes for Mountain Lion beta.
    • show error and keep device closed when unable to open a CoreAudio device.
  • Glue:
    • avoid leaving tiny shards of items in certain instances.
    • use audio device blocksize for better compatibility with take FX.

    • support for binding MIDI/OSC to media explorer actions.
  • MIDI editor:
    • fixed actions to move notes one semitone when hiding note rows and snapping to scale.

  • MIDI file import:
    • fixed bug when importing tempo maps with frequent tempo changes.
    • properly handle snapping odd-numbered 8th-note time signatures.

    • support for assigning sequential inputs for selected tracks.
  • Region manager:
    • avoid autoseek when selecting multiple items, clicking color/render columns.
