The RAM requirement for wideband has gone down
drastically (by more than two times). A new
resampler module has been added, providing fast
arbitrary sampling rate conversion. 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, and should be robust and tolerant of
incorrect capture-playback synchronization. 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.
