On behalf of the FluidSynth development team, I'm happy to announce  
the release of FluidSynth 1.1.0 "A More Solid Fluid".
This is the result of a 6 month development cycle and is the most  
significant release since 1.0.0.

FluidSynth is a software wavetable synthesizer based on the SoundFont  
2 specification.


New features and changes:
  * Extensive work on making FluidSynth more thread safe, resulting in  
better stability.
  * Audio file rendering for MIDI to audio file conversion, faster  
than realtime (#15).
  * Optional libsndfile support for file rendering in different audio  
file formats (wav, flac, ogg vorbis, etc) (#30).
  * Audio and MIDI are synchronized for MIDI file playback.
  * Server can be specified for Jack audio and MIDI drivers.
  * Jack audio and MIDI is now synchronized (when same Jack server used).
  * MIDI file playback is now timed correctly, even with large audio  
buffer sizes.
  * Fixed issue with missing percussion in MIDI files caused by very  
short notes, using synth.min-note-length setting (#1).
  * Improved support for MIDI tuning standard, including SYSEX support  
and realtime tuning activation.
  * Multi-core support for utilizing multiple CPUs for synthesis or  
increasing speed of file rendering.
  * Voices for a note-on event are started synchronously (#46).
  * TCP/IP shell server support for windows (#20).
  * Improved settings output (-o help) (alphabetically sorted and  
string options listed).
  * Audio driver (-a) and MIDI driver (-m) options now accept "help"  
and list available options (#41).
  * Added audio.realtime-prio and midi.realtime-prio for controlling  
realtime scheduling of some audio and MIDI drivers.
  * Default priority levels of audio and MIDI threads set to 60 and 50  
  * All yes/no string boolean settings converted to integer toggle  
settings (with backwards compatibility).
  * glib is now a required dependency.
  * Updated README-OSX
  * Added "voice_count" shell command for getting current number of  
active voices.

New command line options:
  -F, --fast-render=[file]
  -T, --audio-file-type
  -O, --audio-file-format
  -E, --audio-file-endian

New or changed parameters:
  * Audio file output settings: audio.file.endian, audio.file.format,  
audio.file.name, audio.file.type, audio.sample-format
  * Realtime scheduling settings: audio.realtime-prio, midi.realtime-prio
  * Jack settings: audio.jack.server and midi.jack.server
  * Other settings: player.reset-synth, player.timing-source,  
synth.cpu-cores (experimental), synth.min-note-length

Bug fixes and minor changes:
  * Fixed enabling of high priority scheduling in many audio drivers.
  * Fixed bank selection logic
  * Build fixes for mingw and VC++ builds on Windows
  * Fix default values (after MIDI reset) to be more consistent with  
MIDI spec (#29).
  * Removed VintageDreamsWaves-v2.sf2 since it wasn't under a free license.
  * Solaris build fix (#52)
  * Implemented fluid_player_set_loop (#33)
  * Fixed scaletune error (#26)
  * Fixed synth reset between songs (#31)
  * Fixed pitch bend error in Windows MIDI driver (#54)
  * Skip remaining track data in MIDI file after EOT (#53)
  * Bug fix in MIDI router where mutex was left locked with MIDI  
system reset message.
  * Help command now shows list of topics instead of General help.
  * Fixed non-blocking in alsa_raw, alsa_seq and OSS MIDI drivers.
  * Fixed segfault on config file load (#45).

Changes affecting developers:
  * Developer API docs overhauled and now very complete.
  * Lots of code cleanup in fluid_synth.c, fluid_chorus.c,  
fluid_reverb.c and fluid_chan.c.
  * Improved use of settings hints for all settings.
  * char * arguments changed to const char * for many function prototypes.
  * Many new API functions.
