No, I really did split if you look at the 1.1 versions that you have
been shipping. Basically, 1.0 had just the codec. Then 1.1.x introduced
new features in libspeex, which you are currently shipping. Now, I am
moving those new features to libspeexdsp. So basically, the only things
that moved where "unstable" features that hadn't been part of a stable
release yet (but are in libspeex in 1.1.12).

Yes. I believe Ekiga is using the features that are being moved there
from libspeex (e.g. the echo canceller) and the new resampler is now
being used by alsa-plugins and pulseaudio. In the case of alsa and
pulseaudio, I think they use a copy of the code though (because the
resampler is very very new).

I guess I should point out that 1.2beta1 is more stable than 1.1.12
because 1.1.x was an "unstable branch" (just like odd releases for the
kernel used to be). The only difference is that the 1.1.x/1.2beta branch
has long been much superior to the last "stable release" (1.0.5).
Seriously, there's no point in keeping 1.1.12 in stable because it's
just an older unstable release. Consider 1.2beta2 as 1.1.14 (that's
actually how it's identified internally). Also note that 1.2beta2 has no
known issue (except for the resampler, which is a new component anyway
and doesn't affect anything else).

Hope this clarifies things. Any questions?

One last note, I've noticed you seem to ship testenc and even a man page
for it. Those should *not* be distributed and are only for development
use (easy testing). testenc has no value as a tool.
