Brasero will replace Serpentine as the CD-writing utility in the upcoming April release of Ubuntu 8.10 (code-named Hardy Heron). Brasero extends the functionality of Serpentine to include data CD and DVD projects, file integrity checking, and multisession support.
Why replace Serpentine, a dead simple solution for burning audio CDs? It features tight integration into the GNOME Desktop Environment, with support for Rhythmbox playlists and drag and drop file management from Nautilus, as well as the ability to extract audio from video files. Unfortunately, the application has no support for creating data CDs. You can fill that void by using the native CD-writing capabilities inside Nautilus, but Nautilus offers limited options for data project creation.
