<h2>Current <strong style='font-style: italic;'>Unstable</strong> Release (recommended)</h2>
+<h3 id='one.1.2rc1'>1.2rc1</h3>
+<p>This release adds support for acoustic echo cancellation with multiple
+microphones and multiple loudspeakers. It also adds an API to decorrelate
+loudspeaker signals to improve multi-channel performance. In the bugfix
+department, there are fixes for a few bugs in the echo canceller, jitter
+buffer and preprocessor. At this point, the API for 1.2 should be stable
+and only a few very minor additions are planned.</p>

<h3 id='one.1.2beta3'>1.2beta3</h3>
<p>The most obvious change in this release is that all the non-codec components (preprocessor,
echo cancellation, jitter buffer) have been moved to a new <i>libspeexdsp</i> library.

- <p class="submitdate">May 24, 2007</p>
- <div class="description">
- <p>Again, this new releases brings many improvements. The RAM requirement for wideband has gone down drastically (i.e. more than 2x). A new resampler module has been added, providing arbitrary sampling rate conversion -- fast. The echo canceller has also been improved. A bug in 1.2beta1 that made the echo canceller unstable has been fixed. The echo canceller should now converge faster, be robust and tolerant of incorrect capture-playback synchronisation. The preprocessor has also been greatly improved. Not only should the quality be better, but it is now fully converted to fixed-point. At last, early TriMedia support (incomplete) has been merged.</p>

- <p class="submitdate">September 4, 2006</p>
- <div class="description">
- <p>This new release brings many significant improvements. The quality has been improved, both at the encoder level and the decoder level. These include enhancer improvements (now on by default), input/output high-pass filters, as well as fixing minor regressions in previous 1.1.x releases. A strange and rare instability problem with pure sinusoids has also been fixed. On top of that, memory use has been greatly reduced, especially for fixed-point and narrowband. The fixed-point narrowband encoder+decoder memory use has been cut by more than half, making it possible to fit both in less than 6 kB of RAM. In general, CPU requirement had gone down, especially for the fixed-point port. The Blackfin port has been speeded up significantly, thanks to David Rowe. There are also a few fixes for the TI C5X DSPs, as well as better support for C++ compilers and crappy MS compilers. Oh, and before anyone starts worrying, the format (bit-stream) itself has not changed, so S
peex is still compatible with version 1.0 and will continue to be in the future.</p>
- <p>Non-codec improvements include a extension (easier to use) to the echo canceller API and a Speex-independent version of the jitter buffer. The echo canceller should also be more robust to saturation in the capture path. Last, but not least, the documentation has been updated.</p>
