1. A short summary of changes

The JACK slave mode code has been completely rewritten. As a
new feature it is now possible to use libsamplerate for
resampling. Using JACK has been made more user-friendly as ecasound
can now automatically configure the runtime parameters to
match the current server settings. And thanks to build system
and signal handling updates, it's now possible to compile
ecasound for win32 under Cygwin.

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 licenced under the LGPL.

3. Changes since last release

* If configured with JACK-support, ecasound will now fetch the
correct buffer size and sampling rate parameters from the
JACK server when connecting a chainsetup with JACK inputs or
outputs. In other words you don't have to manually match
these settings between the JACK server and ecasound.

* Support for Erik de Castro Lopo's libsamplerate
resampling library added. If libsamplerate is not installed,
ecasound will fall back to the old resampling algorithm.

* Rewritten the code that handles JACK slave-mode operation.
Ecasound is now able to more quickly and reliably follow
transport state and position changes, as initiated by the
current JACK timebase master.

* Ecasound for Windows! :) With help of the Cygwin environment,
you can now compile win32 ecasound binaries straight from
the standard source package. As of 1.3.1, Cygwin also
contains basic /dev/dsp emulation, so even audio playback
works.

* Fixed many, more or less serious, bugs. The most annoying
ones were incorrect handling of the '-t' option, excessive
DBC warnings with JACK inputs and outputs and failing to
properly reset the terminal after a CTRL-C while in interactive
mode.
