[ardour-dev] Ardour 0.9beta28 released

[Paul Davis]

As far as I can tell, all that stands between this release and 0.99 is
some work on MIDI handling that requires that I get my laptop working
again.

The fix that required a release
-------------------------------

   * substantial fix for GUI and other "lock ups" caused by
     appallingly bad thread/parallel programming. This bug
     has existed for 3-4 years without clear detection.

     So far, Nick Mainsbridge has confirmed that this fix
     corrects very repeatable GUI lockups he was encountering, 
     without any apparent side effects.

Other things that have been going on (thanks to Gerard and Sampo)
------------------------------------

  * fixes in automation cut-and-paste
  * pasting automation is now overwrite-paste, replacing 
      automation data that was there
  * fix timestretching. the longstanding problem with the length
    of the stretched region continues, but the GUI now works as 
    intended, and multi-region stretching works.
  * automation line control visibility variations when zooming
  * crossfade positioning after a trim    
  * fixes for reverse and normalize
      - reverse now reverses exactly the region
      - normalize now looks only at the region
        (it would sometimes look for peaks after the 
	 regions end if the soundfile was longer)
  * fix for automation recording/touching when looping.
     (It would create multiple lines on top of each other)
  * some fixes for region gain envelopes when front and end 
     trimming regions
  * prevent removal of first/last visible region gain points
