* Editor: Fix sligthly wrong memory handling. Might
  have led to crashes sometimes after copying a
  range that contains stops, but only after the
  second time or later, and probably only in very
  rare cases. Bug introduced in V6.6.77.
* Midi Learn: Rough implementation of
  "incremental mode". The feature is likely to
  require some tweaking though.
* Sequencer: Make the song tempo automation popup
  menu less confusing.
* Sequencer: Fix gfx garbage in uppermost pixel row
  when song tempo automation is visible.
* Editor: Fix a possible, but if so, probably
  extremely rare, crash when creating undo for range.
  The bug seems to have always been there.
* Internal: Fix memory leak if trying to allocate
  very large memory blocks in realtime code.
* GUI: Attempt to fix Qt sometimes translating
  strings. (That's not supposed to happen since
  Radium is an English-only program.)
* Linux: Turn off crash reporter if radium couldn't
  start because of missing AM pitch shift plugin
  during startup. Only for custom builds though.
* Soundfile saver: Fix pressing "Save" if Qt
  has decided to translate the text "Save" to
  another language. Qt is not supposed to
  translate anything, but reportedly it has.
* Internal: Fix a bug in a function that divides two
  ratio numbers. The bug could in theory have caused
  all kinds of errors, but probably not.
* GUI: Decrease memory garbage collection time
  somewhat.
* API: instrumentEffectMidiLearnIsIncremental,
  setInstrumentEffectMidiLearnIsIncremental.
