1. A short summary of changes

Support has been added for libsndfile. This allows to access
a number of new audio file formats such as W64, PVF and VOC 
files. Integration with libaudiofile and MikMod has also
been improved.  Bugs in the native Python ECI implementation 
have been fixed. Rubyecasound, a Ruby ECI implementation, has
been added to the package. A serious memory-leak in list 
handling functions of the C ECI implementation was fixed. This
bugfix also affects C++, Perl and PHP ECI implementations.  
Compiling Ecamegapedal works again as the header files
missing from the previous 2.3.1 release are now again 
included in the dist-package. Many minor bugs have been fixed.

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.

Ecasound is licensed under the GPL. The Ecasound Control Interface 
(ECI) is licensed under the LGPL.

3. Changes since last release

* Rubyecasound, a Ruby ECI implementation, has been added 
  to the package. Developer documentation can be found 
  at <http://eca.cx/eci>. Rubyecasound was developed by
  Jan Weil.

* Some files were missing from the previous 2.3.1 release
  dist-package. This caused the "make check" test procedure
  to fail, and also prevented from compiling Ecamegapedal
  against 2.3.1. In 2.3.2 the missing files are once again
  included in the dist-package.

* Libsndfile support has been added to Ecasound 
  (development item 'edi-33'). Support for libaudiofile 
  has also been improved in this release. The user
  can now compile in support for both libraries at
  the same time. It is possible to use command-line options
  to select which library to use for a given file. Similar
  improvements have been made to the MikMod support.
  See the ecasound(1) man page for more details.

* Some bugs in libsamplerate integration have been fixed.
  Upgrading to libsamplerate version 0.0.15 or newer is 
  recommended. This release contains a few important fixes 
  that affect Ecasound. A few examples of resampling
  with Ecasound have been added to the docs:

* A severe memory-leak bug was found and fixed in the C ECI 
  implementation. This bug affects applications that heavily
  use EIAM commands that return lists of strings. The C ECI
  is used by C++, Perl, PHP and Python ECI implementations.

* Bugs in the native Python ECI implementation have been
  fixed. The C-based Python ECI implementation is still 
  selected as the default, but you can override this with
  the '--enable-pyecasound=python' option to configure.

  Note, 'native' here means that ECI API is implemented without 
  linking to any Ecasound libraries. Instead the ECI implementation
  forks 'ecasound' binary on the background and communicates with it 
  using pipes. This allows for clear decoupling between ECI apps 
  and specific Ecasound version. More information about ECI can
  be found at <http://www.eca.cx/eci>.
