 Version CVS HEAD (?)
 
+  * packaging changes:
+    - config.h is not going to be installed along with liblinuxsampler's
+      API header files anymore
+    - only the API relevant header (and source) files will be exported to
+      the Doxygen API documentation (explicitly listed in Doxyfile.in)
+    - added completely new XCode project files for Mac OSX which is now
+      capable to execute our autoconf environment, thus no need anymore
+      to maintain the compile time configuration file (osx/version.h) for
+      OSX manually (patch by Toshi Nagata)
+
   * general changes:
     - replaced the old, confusing MIDI program change mechanism by a
       flexible MIDI instrument mapper which allows to map arbitrary
-      (MIDI bank MSB, MIDI bank LSB, MIDI program) triplets with arbitrary
+      (MIDI bank, MIDI program) pairs with arbitrary
       (engine type, instrument file, file index) triplets which will be
       loaded on the respective channel when such MIDI program change
       messages arrive, beside that, each entry allows to define a life-time

       respective program change arrives (to safe RAM space), as well as a
       global volume factor for each entry, so the user can adjust the volume
       dynamic of his mapped instrument collection without having to modify
-      the instrument files
+      the instrument files, also one can manage arbitrary amount of such
+      MIDI instrument maps and assign each sampler channel individually
+      a certain map, so that i.e. separation of normal instruments and
+      drumkits is possible
+    - new notification events for tracking changes to audio/MIDI devices,
+      MIDI instrument maps, MIDI instruments, FX sends, global volume.
+    - sampler was limited to load max. 200 instruments in the background
+      due to a constant size RingBuffer FIFO which is now replaced by a
+      dynamic (unlimited) size std::list FIFO
+    - added FX sends, these allow to route audio signals to arbitrary audio
+      output channels for being processed by external effect processors
+      (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
+      controllers
+    - global (sampler wide) volume can now be controlled at runtime
+    - Implemented new, improved notification system
+    - fixed compilation errors regarding OSX
+      (patch by Toshi Nagata)
+    - implemented instruments database
+    - added highly experimental support for on-the-fly instrument editing
+      within the sampler's process (by using instrument editor plugins),
+      you'll notice the new "Registered instrument editors:" message on
+      startup, added a new LSCP command "EDIT INSTRUMENT <sampler-channel>"
+      to spawn a matching instrument editor for the instrument on the
+      given sampler channel, the plugin path can be overridden at compile
+      time with ./configure --enable-plugin-dir=/some/dir
+    - fixed several issues in fundamental "Thread" class: set scheduling
+      policy and priority on thread level, set a minimum stack size for
+      thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
+      threads simply inherited properties of starting thread instead of
+      setting their own policy and priority
+    - minor fix in our automatic stack trace mechanism on crashes, the
+      main process did not wait for the stack trace process to finish
+      its output
 
   * MIDI driver:
     - dispatch bank select (MSB and LSB) messages
 
+  * audio driver:
+    - the ALSA audio output driver parameters now reflect the correct
+      parameter value ranges for the respective selected sound card
+      (patch by Till Wimmer, a bit fixed and extended)
+
   * Gigasampler format engine:
     - if a filter is used and EG2 finishes before EG1, let the voice
       die when EG2 has finished (this fixes a problem with clicks and
       voice starvation for some gigs)
+    - playback is no longer disabled during instrument loading
+    - all notes playing on a channel that changes its instrument keep
+      playing with the old instrument until they get a note off
+      command
+    - EG fix: a release value of zero could cause noises or crash
+    - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
+    - EG fine tuning: when attack is zero the EG starts at a level
+      above max sustain level, which means that there is a decay phase
+      even if sustain is 100%
+    - more EG fixes: the level could sometimes go below zero and cause
+      noises or crashes
+    - minor fix of EGDecay (patch by Toshi Nagata)
+    - fixed compiler error when --enable-override-filter-type was
+      supplied to the configure script (fixes #46)
+
+  * LSCP server:
+    - fixed compile time error for old Bison versions
+      (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
+    - parser now supports extended ASCII character set
+      (up to ASCII code 255, i.e. includes now umlauts and accents)
+    - filename arguments in LSCP commands now allow to use escape
+      sequences, that is directly literal as one of: \', \", \\, \n, \r,
+      \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
+      code value like \xf2) (fixes bug #24)
 
   * Bug fixes:
     - fixed crash occurring on certain LSCP scripts (Bug 39)
+    - another thread safety fix for lscp "load engine" and "set
+      channel audio output device"
+
+  * test cases:
+    - updated and fixed (haven't been touched in a while)
