Change-log:

- While moving multi-selected MIDI events around the clip editor (aka
piano-roll), with help of keyboard arrow keys, that is, was not clear
which one was the so-called "anchor" event, the one which positioning
gets honored for snap-to-beat business. Not anymore: the anchor event
now defaults to the earliest in time or the one the user's last
point(-click)ed.
- MIDI control observer pattern implementation has sneaked in, making it
ready for the so-called and long-awaited "MIDI Learn" feature and
arbitrary MIDI controller assignment, for plugin parameters in particular.
- MMC DEFERRED PLAY doesn't cause transport state to stop if currently
rolling (mitigating bug #3067264).
- Audio clip merge processing might have been skipping a few initial
frame blocks, now fixed.
- Clip selection and plugin parameter hash optimization.
- Anti-glitch audio clip macro fade-in/out fixed again.
- New clip fade-in/out slopes (curves) are introduced, partially adapted
and refactored from those easing equations of Robert Penner's fame.
- Clip fade-in/out non-linear slopes are now shown as actual WYSIWYG curves.
- Escape key now closes generic plugin widgets as ever found usual
elsewhere.
- Picking nits: unselect current track when clicking on any gray empty
area, also accessible from a new menu item: Track/Navigate/None.
- A nasty and deadly MIDI resolution overflow has been finally fixed,
allowing for long MIDI sequences (1h+) to load correctly on 32bit
machines from now on (was perfectly fine on 64bit though).
- MIDI editor selection hash optimization in face of reasonably huge
event sequences.
- MIDI controller mapping finally refactored to support some other MIDI
event types than just CC (0xBn) ones.
- Nitpicking fix: corrected main track-list (left pane) display when no
track is currently selected.
- libX11 is now being added explicitly to the build link phase, as seen
necessary on some bleeding-edge distros eg. Fedora 13, Debian 6. (fixing
bug #3050944).
- New audio metronome bar and beat sample gain options.
- Progressively, the observer pattern is being finally introduced,
targeting all potentially automation controls and widgets as plain
ground-zero for the (ultra-)long overdue automation feature.
- MIDI controller mapping of still non-existing tracks were being
implicitly assigned to the last, highly numbered, existing track. Now fixed.
- Moving from old deprecated Qt3'ish custom event post handling into
regular asynchronous signal/slot strategy.
- Muting/soloing tracks while playback is looping was leaving current
audio clip out-of-sync whenever that same track is later un-muted on any
other preceding clip. Now hopefully fixed.
- MIDI Clock support makes its first appearance.
- All tempo (BPM) calculations are now compliant to the MIDI
conventional equivalence between beat and quarter note (1/4, crotchet)
as common standard time division.
- Automatic audio time-stretch option is not enabled by default anymore.
- Standard warning Apply button is now only shown when dismissing dialog
changes are actually valid.
- Make sure non-dedicated metronome and player buses are properly reset
and reopen when changing regular audio buses (hopefully fixing bug item
#3021645 - Crash after changing audio bus).
- Hopefully, an outrageously old bug got squashed away, which was
causing random impromptu crashes, most often when importing audio clips
while looping and play-head is any near the loop end point.
- General standard dialog buttons layout is now in place.
- Fixed main track view off-limits play-head positioning.
- Main tool-bar Time and Tempo spin-boxes, may now have their colors
correct, as for most non-Qt based theme engines (ie. Gnome). Green text
on black background has been and still is the the intended aspect design ;)
- MIDI file import and internal sequence representation has been changed
to be inclusive on all bank-select (CC#0,32) and program-change events
which were previously discarded while honoring MIDI track properties.
Interleaved SysEx events are now also preserved on their original
sequence positions instead of squashing a duplicate into the MIDI bus
SysEx setup.
- Attempt to include the VeSTige header by default, as for minimal VST
plugin support.
- JACK transport support has been slightly rewritten, in fact the sync
callback is now in effect for repositioning.
- The MIDI clip editor (piano roll) widget won't be flagged as a tool
window anymore.
- A tempo adjustment tool is making inroads from the menu, as
Edit/Clip/Tempo... (factory shortcut: F7).
- Audio tracks auto-monitoring is now effective on playback.
- Make sure to ask whether a dirty MIDI clip should be saved, upon
resizing or stretching its edges (fixes bug #3017723).
- Backward and Forward transport commands are now taking additional
stops on loop points.
- Attempt to optimize track solo/mute redundant transactions, in special
regard to MIDI track events which were being duplicated on soloing and
temporarily muted on unsoloing.

Cheers && Enjoy (be happy!)
