Development seemed to halt some time after 2002, with no public updates to the site and source code for several years, but resumed in August, 2006 with the prerelease of version 10.0. The current development version is still based on cdda2wav code from 1997 and thus does neither contain support for extracting meta data from audio CDs nor workarounds for typical logical defects in CDs that prevented audio extraction with old versions of cdda2wav (such as audio tracks that are marked as data tracks).
