+Version CVS HEAD (?)
+
+  * packaging changes:
+    - install necessary development header files for allowing 3rd party
+      applications to link against liblinuxsampler
+    - liblinuxsampler's API documentation can be generated with 'make docs'
+      (Doxygen required)
+    - added benchmark to automatically detect the best triangle LFO
+      implementation (currently either an integer math solution or a
+      di-harmonic approximation), automatic detection can be overriden
+      with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
+      configure script argument though (mandatory for cross-compilation)
+    - do not automatically pick optimized gcc flags if the user already
+      provided some on his own (as CXXFLAGS)
+    - added compile time option to disable processing of All-Notes-Off MIDI
+      messages
+    - added compile time options to allow disabling the various audio and
+      MIDI drivers
+
+  * Gigasampler format engine:
+    - extensive synthesis optimization
+      (reimplementation of EGs and LFO(s), removed synthesis parameter
+      prerendering and the synthesis parameter matrix in general, splitting
+      each audio fragment into subfragments now where each subfragment uses
+      constant pitch and filter coefficients. The volume coefficient is
+      linearly interpolated inside a subfragment, unless
+      --disable-interpolate-volume is set.)
+    - fine tuning of the EG modulation parameters
+    - improved filter cutoff calculation by adding support for the
+      following gig parameters: Cutoff freq (used when no cutoff
+      controller is defined), Control invert, Minimum cutoff, Velocity
+      curve and Velocity range. The keyboard tracking now scales
+      cutoff frequency instead of resonance.
+    - filter fine tuning: calculation of cutoff frequency and
+      bandwidth improved. Removed use of "BasicBPFilter". Changed
+      bandpass filter from constant peak to constant skirt. Added
+      support for gig parameter Resonance.
+    - fixed bug in sysex handling (patch by Juan Linietsky)
+    - added global volume attenuation of -9 dB (0.35f) to prevent clipping
+      which can be overridden with --enable-global-attenuation
+    - EG fixes: made the length of "attack hold" stage more
+      accurate. Release stage can now start before attack stage
+      ends. Cancel release didn't work when sustain was zero. Attack
+      time now has a minimal value to prevent clicks.
+    - fixed pitch changes larger than one octave
+    - fixed EG3 (pitch envelope) synthesis which was neutral all the time
+    - implemented portamento mode and solo mode (a.k.a 'mono mode'):
+      all modes can be altered via standard GM messages, that is CC5 for
+      altering portamento time, CC65 for enabling / disabling portamento
+      mode, CC126 for enabling solo mode and CC127 for disabling solo mode
+    - fine tuning of the curves for volume (CC7), pan (CC10 and gig
+      parameter) and crossfade
+    - added support for the "attenuation controller threshold" gig
+      parameter
+    - added smoothing of volume changes caused by control change
+      messages
+
+  * LSCP server:
+    - fixed application exit on broken pipe error (fixes bug #20)
+    - fixed the notification messages delay due to lack of
+      network activity (fixes bug #26)
+    - fixed parser bug which occured on space(s) within device parameters
+      (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
+
+  * audio driver:
+    - added aRts audio output driver (by no means RT safe)
+
+  * MIDI driver:
+    - fixed legacy sysex code which caused dispatching of MIDI SysEx
+      messages several times instead of once
+
+  * general changes:
+    - support for muting sampler channels and solo mode of the same, two new
+      LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
+      fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
+      introduced for this, the behavior is the same like on a mixer console
+      (patch by Grigor Iliev, a bit adjusted). Also added configure option
+      --enable-process-muted-channels which can be used to enable the
+      processing of muted channels.
+    - support for sostenuto pedal
+    - support for monitoring the total number of active voices
+      (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
+      SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
+    - fixed some memory management errors
+    - fixed some concurrency problems that could lead to crashes when
+      LSCP commands were executed
+
