Just to let you know that Speex 1.0.1 is out.
"This release fixes several minor bugs that were found in version 1.0 as well as a major bug in the wideband encoding. This makes files encoded with 1.0 play with lower quality on 1.0.1 decoders. Upgrading to 1.0.1 is highly recommended, especially for wideband users. As such, reencode wideband files using a 1.0.1 encoder if you can."
