1. Summary of changes
Serious bugs in multitrack sync code, ECI C implementation and
big-endian platform support have been fixed. Support has been 
added for input and output of FLAC, AAC and M4A files. Improvements 
have been made to both FreeBSD and Mac OS X support. Many minor
improvements to ECI implementations and user documentation.

2. What is Ecasound?
Ecasound is a software package designed for multitrack audio
processing. It can be used for simple tasks like audio playback, 
recording and format conversions, as well as for multitrack effect 
processing, mixing, recording and signal recycling. Ecasound supports 
a wide range of audio inputs, outputs and effect algorithms. 
Effects and audio objects can be combined in various ways, and their
parameters can be controlled by operator objects like oscillators 
and MIDI-CCs. A versatile console mode user-interface is included 
in the package.
Primary platform for running Ecasound is GNU/Linux. Ecasound can 
also be run on many UNIX-derived systems such as FreeBSD, Mac OS X 
and Solaris. Limited support for Windows is available through 
Cygwin. Ecasound is licensed under the GPL. The Ecasound Control 
Interface (ECI) is licensed under the LGPL.

3. Changes since last release
* FLAC support added. The 'flac' tools is used for both
  encoding and decoding.
* AAC/M4A/MP4 support added. The 'faad' and 'faac' tools are used
  for encoding and decoding.
* Improved support for both FreeBSD and Mac OS X. Ecasound should now
  compile out-of-the-box on recent releases of these systems.
* A critical bug was fixed in multitrack-offset calculation code.
  This bug was triggered by ALSA devices that limit playback 
  period count to two (for example rme9652 and cs4281).
* Minor fixes to both mp3 and ogg input support.
* Many improvements to the C ECI implementation: Bug which caused 
  losses of sync between clients and the engine was fixed. Float 
  return values are now returned with higher precision. These 
  improvements affect all ECI implementations that are based on
  libecasoundc (Perl, Python, PHP interfaces).
