081112:

Preliminary JACK transport support:

- Send JACK transport start/stop/locate.

Class improvements and new classes:

- Added 'morph' class that interpolates between two inputs
  linearly or according to a control input. Vectors and hashes are
  handled recursively. The interpolating function can be customized.
  See examples/morph_test.as for an example.

- Clip 'x' to 0.0-1.0 in 'funcbus' class.

- The 'funcbus' class now handles get_event() and has an 'event' inlet
  that is used to get event times for synthesized events. This can be
  used to pack events by combining different inputs and expressions.
  See examples/event_pack.as for an example.

- The 'datagen' class now exports an 'inlets' variable for direct access
  to the inlets, for use of Inlet.get_connections() and such.
  See examples/datagen_evget.as for an example.

Appearance and user interface:

- Integrate with the native OS X app menu bar.

- Support one-button mice: use Command-click as right-click on OS X.

- Change cursor appearance when moving/resizing/aligning/etc...

- Clickable toolbox icons.

- Ctrl-double-click to open properties window.

Bug fixes:

- Fixed drawing bug in ASPlotObj base class.

- Fixed bug in ASObject.val_finder_num() that made it return
  default value if input was a numeric 0.

- Some more explicit destroying of cairo contexts, also do the same
  with cairo surfaces.

081105:

- Fixed bug in OSC/MIDI event sort.

- Updates to AlgoScore Users Manual: how to build an OS X universal app
  that actually works.
  
- Link to liblo even if it's not pulled in by csound.

- OSC support: Use gettimeofday() instead of clock_gettime() on systems
  without POSIX highres timers (like OS X).

081103:

- Updated build system for Mac OS X.

- Free cairo contexts explicitly after usage instead of leaving them for
  the garbage collector. Fixes crash under GTK Quartz on Mac OS X.

- Set gtk-error-bell to 0, fixes annoying beeps on some systems.

- Updates to AlgoScore Users Manual.

- Disable OSC support if system doesn't have POSIX timers.

- Added Inlet.val_finder_num() that returns default value if value is
  not a single numeric.

- Use val_finder_num() in classes defined in plot.nas

- Added 'interpolation' out property on jitter object.

- Fixed bug in ASObject.default_get_value() that returned nil if first
  event didn't start at time zero.
  
- Fixed bug that gave an error when creating an OSC bus.

- Added some more examples.

- Improved OSC sequencer, don't use a fixed tick resolution but
  output the events at the right time. This means less CPU
  usage and more precise timing.

081027:

- OpenSoundControl output through 'osc_bus' object.

  Each bus has an 'osc_address' in the form 'osc.udp://hostname:port',
  and a 'controllers' property, which takes a table of inlet names and
  their OSC path and typetag strings:
  
  { freq: ['/foo/bar/freq','f'],
    note:  ['/zoo/note','iff'],
    ...
  }
  
  A running JACK server is still needed, though OSC output isn't actually
  using it. (This might change in the future)
  
  The OSC output time resolution is 5 mS for the moment, defined in
  playbuslib.c. (This might also change in the future)

- Display warning message if there's no exportable busses in the score
  when doing File->Export bus.

- Double click on object to enter edit mode.

- Fixed some behaviour of edit mode.

- Use (unsigned int) instead of (useconds_t) in src/nasal/unixlib.c

081020:

- Now also builds and works with double precision Csound

- MIDI bus export to file.

- Merged new nasal features from Andy Ross:

  * Call-by-name argument lists to functions. You can now pass a hash
    literal as the argument list of a function to define the local
    variable lists, e.g.: "rect_area(width:12, length:24)"

  * Multiple assignments. You can now parenthesize a list of lvalues to
    be assigned in one statement, e.g.:
  
    (a, var b, var c) = (1, 2, 3);
    (h["foo"], o.fld, v[99]) = (3, 4, 5);
    (a, b) = [1, 2];        # It even works with runtime vectors
    var (a, b) = (1, 2);    # shorthand for "(var a, var b)"

  * Vector slicing. You can now generate a vector from a list of indices
    or ranges, e.g.:

    var (uid, gid, size) = io.stat(filename)[4,5,7];
    var tail = list[1:];
    var prefix = list[0:length];

- Merged nasal updates and bugfixes from Andy Ross

- math.mirror() now handles multiple reflections by iterating until
  the value is within range.

080512:

- Added function math.betarand(a,b), a beta distribution random generator.

- Added optional mode parameter to math.trirand(mode=0.5) to set center of
  the distribution.
  
- Added function math.pdf2cdf(v) to convert a probability density table
  to a cumulative distribution table.
  
- Added function math.userrand(cdf), a random generator with distribution
  according to the cumulative distribution table cdf.

- Added optional strength parameter to math.quant(x, q, s=1).

- Noise and Jitter objects now has 'randomizer' properties for customizing
  the random generator, for example to use other distributions.
  This can also be used to construct brownian motion:
  'math.mirror(last+(math.rand()-0.5)*0.3,min,max)'
  where 0.3 is the maximum stepsize.

- FuncBus changes:
  - a variable 'init' is 1 at the first evaluation after an update.
  - save the namespace between evaluations.
  Note the limited usage of these features, doing something like
  'if(init) math.seed(42); math.rand();' does not yield a reproducable
  sequence since 'init' is still 0 after the *receiving* objects updates,
  and we don't know when or in what order those objects asks for a value.

- Added 'plot' module to plot functions in a separate window. Example:
  w = plot.new(func(x) math.sin(x), -math.pi, math.pi)

- Fixed bug in console window that produced an error when the
  commandline history was full. 
  
- Added obj.xy_inside() to detect click inside object, and
  obj.get_con_top_ypos() and obj.get_con_bottom_ypos() to get vertical
  connection position, so that subclasses can override this to correspond
  more to the graphical appearance of the object.
  Changed TextBus class to use this.

- Fixes to OS X AlgoScore.app:
  - AS logo should now be shown in about dialog also on OS X.
  - Just launch AS through a script instead of using the compiled wrapper.
  - Run xmodmap to use Command key as mod1 instead of Alt to work around
    GTK vs X11 config problem.

- Added 'printerr' function that prints error message in different color
  and raises the log window.

- Notify user at JACK shutdown.

- Warn if csound and JACK samplerates mismatch.

- Made the message dialog about custom userdata folder a bit more clear,
  and mentioned it in the manual.

- Handle multiple arguments in browser and editor settings, so that stuff
  like 'open -e' works.

- Updates to the Users Guide.

- Removed the pre-built linux binary, a separate binary package might be
  released on demand.

080417:

- ASObject.update(): call cancel_generate() on all objects later down the
  dependency graph so that any running rendering threads don't try to access
  data in source objects. (fixes crash when moving objects while rendering)

- Report and recover from any runtime errors in background rendering threads.

- Fixed crash with signal_bus due to trying to close a soundfile twice.

080416:

- Removed the font cache check in the OS X launcher script. It made AlgoScore
  fail to start on some systems.

- Re-create jack ports instead of renaming them on systems with "old" JACK.

- Signal bus: render in background thread. Write data in chunks for faster
  performance.

- clear ringbuffers before starting play, to make sure it starts from silence.

- Moved 'aux_inputs' from ASPlotObj to a separate AuxInputs class layer and
  reused it in the CodeBus base class.
  
- Made 'funcbus' and 'datagen' classes use 'in.NAME(t)' for accessing inputs,
  for consistency.

- editor.nas: Default to 'open -e' for external editor on OS X and $EDITOR
  variable on other platforms.

- Show bus caption in export bus dialog, for easier identification of busses.

- Changed the way the logwindow printing works, now append the text instead of
  replacing the whole buffer. The 'max_log_size' was removed, but the logwindow
  can now be cleared with Ctrl-L.
  
080412:

- Fixed old jack midi API checks in playbuslib.c

- Added 'signal_bus' to stream control data through JACK for high
  resolution control of other applications.

- Added beginning of a 'sndfile' nasal module.

- Removed the concept of audio regions. It's currently not used and only
  complicate things. Let each bus have only one soundfile cache.

- Removed 'audio_bus' and 'sndfile' classes.
  
- JACK ports are now enumerated with two-digit number.
  
- Can now reconnect to JACK in case of JACK crash or zombification due
  to timeout. Use the "Reconnect JACK" item on Score menu.

- ASPlotObj: Clear caption string if transfunc is cleared.

- Added object inspection window (press 'I' on an object)

- Don't wait for process to return in browser.open_uri() and
  editor.open_file(). Fixes bug that made AS freeze until the called
  executable returns, like when the browser wasn't already running.

080408:

- Updated src/CMakeLists.txt, should now build on Mac OS X again.

- Updated OS X build instructions in the Users Manual.

- Explicitly disable rtmidi and rtaudio when calling csound in cs.nas

- make_build now renames the old algoscore binary so that a new one
  will be built automatically.

- Updated README and AppRun script.

080406:

- Now depends on JackOSX 0.76 on OS X.

- Added even more verbose license notices to each sourcefile, since
  this is required for hosting at gna.org

- Moved to CMake build system, run the make_build script in the
  src folder to build AlgoScore.

- Updates to users manual, added documentation of baseclasses from
  algoscore.nas, extracted from source files with a sed script.
  
- Added Help menu with about dialog and link to included users manual.

- Added browser.nas module to handle opening of URIs, defaults to
  "open" on Mac OS X, on other systems the value of $BROWSER variable
  or "firefox" if not set. The browser can be overridden in preferences.

080401:

- Updated class descriptions, and made the function that exports those
  convert it from pango markup to txt2tag markup for automated inclusion
  in the manual.

- Mac OS X app bundle: fixed ScriptExec xcode project,
  should now compile for both ppc and intel.

080331:

- Updates to users manual. Now using txt2tags for HTML generation.

- Simplified examples/evgen_test.as

080328:

- Added copyright and license notices to included nasal files.

- Upgraded to GNU GPL 3

080327:

- Set window icon

- Fixed the dark theme, now with white text on dark background.

- Fixes in inverted score palette file.

- Added copyright and license notices to sourcefile headers

080326:

- If user_data_dir does not exist, open up a dialog to choose
  or create the folder, and save it to options.

- Escape "'" chars in debug.nas:dump(). It was this bug that made
  examples/transfunc_aux_test.as fail to open.

- Read gtk theme file before creating any widgets.

- Fixes in dark.theme, but still can't get common widget foreground other
  than black with gtk 2.12, so I lightened up the background for now...

- HAVE_CSOUND automake conditional wasn't defined if csound wasn't found,
  it's now set to false.

- Added /usr/local to CPPFLAGS and LDFLAGS in configure.in since many
  systems seems to need this...

080319:

- Don't autostart jack server (this should be handled by the user imho)

- Removed check for csound.h in configure.in

- Isak Johnsson added scripts to make a binary OS X application bundle,
  based on scripts from Inkscape. Thanks Isak!

- Updates to users manual

080318:

- ASPlotObj (and all derived classes) now has a transfer function
  property that can be used to transform the data, which will also
  be visualized in the graph.
  The transfer func is called with the following variables set:
    x, t, length, outlet, in, math
  This means for example that a LinSeg with shape [0,1,1] can be
  used to make arbitrary mathematical functions, like math.sin(x*6.283)
  for a one-cycle sine shape, etc...
  
- ASPlotObj now has an 'aux_inputs' property, which can be accessed
  from the transfer function, example:
    aux_inputs = ['amp']
    transfer_func = x*in.amp(t)

- Jitter class now has 'mindur' and 'maxdur' inlets.

- Fixed a bug in FuncBus class

- Fixed a bug in drawing of unupdated region of busses.

- Lots of additions and screenshots to the user manual:
  getting started, using csound, examples.

080317:

- More fixes for OS X build: let AC_CHECK_FRAMEWORK
  add "-Wl,-framework,$1" to $LDFLAGS

- Updates to user manual.

080315:

- CodeBus and derived classes now has a 'inputs' property for the list
  of inlets instead of creating them dynamically.

- If a project tries to connect to non-existing inlets, they are created.

- Updates to user manual.

- Fixed some building problems for Mac OS X, bugs in configure script and
  some missing includes.

- Don't print "buffer underrun" in jack process() since it will take too
  much time, leading to jack shutdown...

- Added this ChangeLog (better late than never)
