It's been a whole month since the last release of the 0.3 series.
The reason for this is not because nothing happened since then (quite the contrary) but rather that we are waiting for the next patch level Qt release.
For 0.3 alpha 2 we finally switched from portaudio to QtMultimedia which fixed some long standing issues on Ubuntu. However, it also introduced a few new issues because Qt 4.6.2 still has some nasty bugs in this area.
Luckily, the Qt software team is incredibly responsive and the most important bugs have already been fixed in their current development version.
Because two of these bugs are blockers for simon (QtMultimedia always uses default output device on Linux, Not supporting 16 kHz recordings on Windows) we sadly have to wait for Qt 4.6.3 to be released before we can release a new test version.
